Quick-connect sealing tools for hydraulic and pneumatic component testing, proof testing, and fluid transfer. Simplify the connection process, reduce cycle time, and eliminate the safety risks of threaded fittings under high pressure.
Fluid power manufacturing is a high-pressure environment—literally. Hydraulic components routinely operate at 3,000 to 5,000+ psi, and every hose assembly, cylinder, pump, motor, valve, and manifold must be leak tested and proof tested before it leaves the factory. Traditional threaded test connections are slow, create repetitive strain injuries, and introduce safety risks when operators wrench on fittings that will be pressurized to thousands of psi within seconds.
FasTest fluid power connectors and hydraulic connectors eliminate all of that. Our quick-connect sealing tools attach to hydraulic and pneumatic ports, threads, tubes, and hose ends in seconds—without wrenches, thread tape, or sealants. Pressure-assisted sealing technology increases seal force as test pressure rises, ensuring the connection gets stronger under pressure rather than weaker. The result is faster cycle times, safer operations, and more consistent test results across every shift.
Whether you’re testing hydraulic hose assemblies, proof testing cylinders, qualifying pumps and motors, or running production leak tests on manifolds and valve bodies, FasTest has the fluid power connectors, hydraulic connectors, and fluid power test equipment to improve your process.

Fluid power testing is fundamentally different from most other manufacturing leak testing applications. The pressures are higher, the media are more aggressive, and the safety stakes of an unexpected disconnection are significant. Here’s why purpose-built fluid power connectors and hydraulic connectors matter:
Precision engineered tools provide the highest quality connection and seal for accurate testing.
Easy-to-use one hand operation, eliminate the painful twisting motions of standard fittings.
FasTest’s ergonomic tools instantly attach to ports and threads - no wrenches, thread tape, or sealants for a leak-tight seal.
Multiple safety features are included in every tool, including pressure assisted sealing technology.
Engineered for precision and durability to withstand rigorous testing environments.
Engineered for the highest quality connection and seal. Reduce False Failures caused at the connection points.
We transform connection tools into tailor-made solutions to fit your exact requirements. Our Team of engineers will work with you to identify and design the optimal Connection Tool for your testing needs. Having difficulty sealing a unique port? Issues with clearance? Work with our dedicated team of Custom Experts to build your perfect solution.

A: FasTest provides fluid power connectors for hydraulic hose assemblies, cylinders, pumps, motors, control valves, manifolds, pneumatic components, hydrostatic drives, actuators, hydraulic tubing and pipe, test ports, heaters, heat exchangers, and accumulators. Both standard and custom-engineered connectors are available.
A: FasTest offers fluid power connectors across a wide pressure range. Standard products cover most common hydraulic and pneumatic test pressures. High-pressure connectors like the FasMate® FN series are rated to 5,000 psi (345 bar), and the HPB series handles even higher-pressure proof testing applications. Custom connectors can be engineered for specific pressure requirements.
A: FasTest fluid power connectors are available for JIC (SAE 37°), SAE O-ring boss, ORFS (O-ring face seal), BSP (British Standard Pipe), metric, and NFPA port patterns. Custom configurations for proprietary or non-standard port types are available through our engineering team.
A: Yes. FasTest provides seal material options compatible with petroleum-based hydraulic oils, synthetic fluids, water glycol, phosphate esters, biodegradable fluids, and other common hydraulic media. Contact our team for seal material recommendations for your specific fluid.
A: FasTest fluid power connectors eliminate the need for wrenching onto test ports under time pressure—the primary cause of cross-threading, incomplete engagement, and energized disconnection injuries. Pressure-assisted sealing technology increases seal force as pressure rises, and safety locking mechanisms prevent accidental disconnection during the test cycle.
A: Yes. FasTest fluid power connectors are used in both manual and automated test environments. Pneumatically operated connectors and ICON™-equipped tools provide the PLC-integrated seal confirmation and actuation needed for automated test cells, robotic handling, and semi-automated multi-station configurations.
A: Proof testing pressurizes a component to a level significantly above its rated working pressure (typically 1.5x to 2x) to verify structural integrity. Because proof test pressures are the highest pressures the component will ever see, the test connection must be rated for these extreme levels. FasTest fluid power connectors are designed and rated for proof test pressures, with pressure-assisted sealing that ensures the connection is most secure at peak test pressure.
A: Yes. FasTest’s custom engineering team designs connectors and fixtures for non-standard fluid power applications—unusual port geometries, high-pressure requirements, multi-port fixtures, and specialized test station integration. Start with an Application Evaluation for a recommendation.
A: Hydraulic testing typically involves higher pressures and liquid media (oils, fluids), while pneumatic testing uses lower pressures with compressed air or nitrogen. FasTest offers connectors optimized for both: high-pressure hydraulic connectors with fluid-compatible seals, and pneumatic connectors with seal materials optimized for gas service. Some FasTest connectors handle both hydraulic and pneumatic applications.
