Engine Testing Connectors: Complete Packages for Every Port on the Line
A complete, engineer-designed set of testing engine connectors for leak testing, pressure decay testing, and fluid transfer across your entire engine or powertrain assembly.
A complete, engineer-designed set of testing engine connectors for leak testing, pressure decay testing, and fluid transfer across your entire engine or powertrain assembly.
FasTest Engine Packages solve this by delivering a complete system of engine testing connectors, custom-matched to every connection point on your engine assembly. Our applications engineers evaluate your specific engine block, cylinder head, intake and exhaust manifolds, coolant and oil galleries, fuel lines, turbocharger connections, and all other test points—then configure a turn-key package of testing engine connectors that seal consistently, connect in seconds, and eliminate the false failures caused by poor tooling.
The result: faster takt time, more reliable test data, reduced scrap, and fewer repetitive motion injuries for your operators. Your engineers can focus on building engines, not building test tools.
Most engine manufacturers start with in-house test tooling because it seems faster and cheaper. But over time, the hidden costs compound:
FasTest Engine Packages replace this patchwork approach with a single, engineered system of engine testing connectors designed specifically for your assembly.
Every FasTest Engine Package is configured by our applications engineering team to match the specific ports, threads, flanges, and connection points on your engine assembly. A typical package includes testing engine connectors and tooling for:
| Connection Point | FasTest Approach |
|---|---|
| Oil Galleries & Drain Ports | Internal and external sealing connectors matched to gallery bore diameters and thread specifications. Pressure-rated for oil circuit pressure decay testing. |
| Coolant Passages & Water Jacket Ports | Quick-connect engine testing connectors for coolant circuit leak testing. Seal to hose barbs, threaded ports, and open bore connections without thread tape or sealant. |
| Intake & Exhaust Ports | Cradle-style and flange-mount connectors (FEG series) for sealing to manifold flanges, turbo flanges, and open-face ports. Custom-profiled for exact port geometry. |
| Fuel Line Connections | High-pressure sealing connectors for fuel rail, fuel injector bore, and return line testing. Rated for fuel system test pressures. |
| Turbocharger Connections | Custom external cradle connectors engineered for turbo inlet, outlet, and oil feed/return port geometries. |
| Threaded Bores & Sensor Ports | FasMate® FN internal high-pressure connectors for threaded bores up to 5,000 psi (345 bar). Ideal for sensor ports, pressure tap locations, and plugged test points. |
| External Threaded Connections | Series 60 connectors for standard and custom external thread sizes up to 750 psi (51 bar). One-handed connection without wrenches. |
| Transmission & Gearbox Ports | Sealing connectors for transmission fluid circuits, gear case leak testing, and valve body test connections. |
| Plugs & Caps | Dedicated sealing plugs for ports that must be blocked during specific test sequences. Matched to port geometry for repeatable seals. |
Every package also includes system documentation, recommended maintenance parts lists, and operating instructions so your team can maintain optimal performance over the life of the tooling.
FasTest Engine Packages are built around ICON™ (Intelligent Connection) technology—the same platform that powers FasTest’s industry-leading leak test connectors across automotive, HVAC-R, aerospace, and medical applications.
At the heart of ICON™ is SURE SEAL™, FasTest’s patented seal confirmation system. When an operator connects a FasTest testing engine connector to a port, SURE SEAL™ provides positive tactile and visual feedback confirming that a leak-tight seal has been achieved. This eliminates the most common source of false failures in engine leak testing: operator uncertainty about whether the connection is properly sealed.
FasTest Engine Packages are not limited to traditional internal combustion engines. Our applications engineering team configures testing engine connectors for the full range of modern powertrain assemblies:
Gasoline and diesel engine blocks, cylinder heads, and assembled engines for passenger vehicles, commercial trucks, off-highway equipment, and marine applications. Typical test points include oil galleries, coolant jackets, intake/exhaust ports, fuel circuits, turbo connections, and sensor bores. FasTest engine testing connectors replace the clamps, pad seals, and improvised adapters that cause false failures and slow down your test line.
EV motor housings, inverter enclosures, and integrated drive units require precision leak testing for coolant circuits and environmental sealing. FasTest testing engine connectors for EV applications are designed for the unique port geometries and lower-pressure test requirements of electric powertrain components.
Hybrid powertrains combine ICE and electric components, often with shared cooling circuits and complex fluid routing. FasTest Engine Packages can address both the high-pressure sealing requirements of the combustion engine and the precision sealing needs of the electric motor and power electronics in a single integrated connector package.
Automatic, manual, and CVT transmissions require leak testing of fluid circuits, valve bodies, and case seals. FasTest provides testing engine connectors for transmission-specific port types, including low-pressure ATF circuits and high-pressure hydraulic test points.
In-process testing of cylinder heads, intake manifolds, exhaust manifolds, oil pans, and other sub-assemblies before final engine build. FasTest connectors ensure these components are tested with the same precision and repeatability as the completed engine assembly.
| In-House / Mixed Tooling | FasTest Engine Package | |
|---|---|---|
| Seal Consistency | Varies by tool condition, operator technique, and fixture wear | Engineered seals with SURE SEAL™ confirmation on every connection |
| False Failure Rate | High — poor seals are the leading cause of false test failures in engine manufacturing | Dramatically reduced — confirmed seals mean test failures reflect actual defects |
| Operator Ergonomics | Wrenches, thread tape, clamps; repetitive motion injuries over time | One-handed, push-to-connect tools; no wrenches or sealants |
| Cycle Time | Extended by manual threading, wrench operations, and re-seating | Seconds to connect and confirm; measurable takt time improvement |
| Setup to Production | Weeks to months of internal design, fabrication, and iteration | Engineered, validated, and delivered production-ready by FasTest |
| Engineering Resources | Your engineers design, fabricate, and maintain test tooling | Your engineers focus on engines; FasTest handles the tooling |
| Maintenance | Ad hoc replacement of worn parts from multiple sources | Single-source maintenance parts, documentation, and technical support from FasTest |
| Data Integration | Typically none — no seal confirmation signal | SURE SEAL™ provides digital seal confirmation for PLC integration |
| Leak Masking Risk | Pad seals and clamps can deform sealing surfaces, masking real leaks | Precision-engineered connectors replicate real-world conditions; leaks are identified, not hidden |
Getting a FasTest Engine Package for your assembly line is a straightforward, engineer-led process:
Share Your Application: Send us your engine drawings, port specifications, test requirements (pressures, media, cycle time targets), and station layout. Not sure what you need? Start with a FasTest Application Evaluation—our team will guide you through the process.
Engineering Review: FasTest applications engineers review every connection point on your assembly and recommend the right connector type, sealing method, and tooling configuration for each port.
Package Design: We configure a complete system of engine testing connectors—connectors, hoses, fixtures, plugs, and documentation—validated to work together as an integrated package.
Validation & Testing: Components are tested as a system before shipment to verify seal integrity, flow performance, and ergonomic function at each connection point.
Delivery & Support: Your engine package arrives production-ready with operating instructions, maintenance parts lists, and access to FasTest’s technical support team for the life of the tooling.
Every Engine Package is custom-configured, but these FasTest connector families appear most frequently in engine and powertrain testing applications:
One-handed quick-connect engine testing connectors for external threads up to 750 psi (51 bar). The workhorse connector for oil drain ports, coolant ports, and sensor locations with standard external threads. No wrenches, no thread tape—push to connect, SURE SEAL™ confirms the seal.
High-pressure testing engine connectors for threaded bores up to 5,000 psi (345 bar). Ideal for fuel system test points, high-pressure oil galleries, and sensor bore connections where internal thread sealing is required.
Custom cradle-style connectors for flanged ports, turbocharger connections, and irregularly shaped openings. FEG connectors are profiled to match the exact geometry of your flange or port face, providing a reliable seal without clamps or bolts.
For non-standard port geometries, unusual clearance requirements, or unique testing conditions, FasTest’s custom engineering team designs purpose-built engine testing connectors tailored to your exact specifications. If a standard connector doesn’t fit, we’ll build one that does.
A FasTest Engine Package is a complete, custom-configured set of engine testing connectors designed for a specific engine or powertrain assembly. Rather than sourcing individual connectors and building your own test tooling, an Engine Package provides matched connectors, plugs, hoses, fixtures, and documentation for every connection point on your engine—all engineered and validated by FasTest to work together as a system.
FasTest Engine Packages cover the full range of powertrain architectures including internal combustion engines (gasoline and diesel), electric vehicle motor and inverter housings, hybrid powertrain assemblies, transmissions, gearboxes, and engine sub-assemblies such as cylinder heads and intake manifolds. Our applications engineers configure the right testing engine connectors for your specific assembly regardless of platform.
A typical Engine Package includes engine testing connectors for oil galleries and drain ports, coolant passages and water jacket ports, intake and exhaust manifold flanges, fuel line connections, turbocharger ports, threaded sensor bores, transmission fluid circuits, and any other ports that require sealing during leak testing, pressure decay testing, or fluid transfer operations.
False failures in engine leak testing are most commonly caused by inconsistent or incomplete seals at the connection points. FasTest engine testing connectors are precision-engineered for each specific port and include SURE SEAL™ technology, which provides positive confirmation that a leak-tight seal has been achieved. When the seal is confirmed and a test still fails, your team knows the issue is in the engine—not the tooling.
SURE SEAL™ is FasTest’s patented seal confirmation system built into ICON™-equipped connectors. It provides tactile and visual feedback when a leak-tight seal is achieved, eliminating operator uncertainty and preventing false test failures. SURE SEAL™ data can also be integrated into PLC-controlled test stations for automated seal verification.
Individual connectors solve one connection point. An Engine Package addresses your entire test station. FasTest engineers evaluate every port on your assembly, select the right connector for each, design the tooling layout for ergonomics and cycle time, and validate the complete package as a system before delivery. The result is optimized performance you can’t achieve by assembling components independently.
Yes. FasTest has a dedicated custom engineering team that designs testing engine connectors for non-standard ports, unusual clearance situations, and unique sealing requirements. Start with an Application Evaluation and our engineers will assess your challenge and propose a solution.
