FasTest 60 Series: Quick-Connect External Thread Connector for Leak Testing and Filling
The Industry-Standard External Thread Quick Connector
The FasTest 60 is the most widely used quick-connect external thread connector in manufacturing leak testing. It connects to virtually every external threaded fitting and compression connection found in production testing—NPT, BSPT, BSPP, JIC 37° flare, ORFS, metric, 45° flare, compression fittings, and custom thread configurations—with a simple push-on, pull-off sleeve action rated to 750 psi (51 bar).
The FasTest 60’s sleeve actuation makes it the fastest way to connect to an external thread on a test station. The operator pushes the connector onto the thread or fitting, the internal collet grips behind the threads, and the seal engages—all in a single motion. To disconnect, pull the sleeve and lift off. No wrenching, no threading, no tools. The collet design locks securely into the threads without damaging them, and a floating piston ensures the seal is properly positioned against the face or ID sealing surface regardless of thread length variation.
For over 40 years, the FasTest 60 has been the go-to connector for automotive engine test lines, HVAC-R component testing, fluid power proof testing, aerospace tube assembly testing, appliance manufacturing, and any application where external threaded ports need fast, repeatable, non-damaging test connections. It’s the connector that built FasTest’s reputation as the industry leader in sealing connection tools—and it remains the most configured and most shipped product in the FasTest catalog.
The FasTest 60 is available with ICON™ intelligent connection technology for digital seal verification and PLC integration, and with an optional internal shut-off valve that stops flow upon disconnection for clean, drip-free operation.
Push On, Pull Off — The Sleeve Connection Explained
-
Push on: The operator pushes the FasTest 60 straight onto the external thread or fitting. The tapered entry guides the connector over the thread crest with minimal effort.
-
Collet locks: As the connector is pushed into position, the internal collet engages the threads. The collet locks behind the thread crest, gripping securely without rotating on the threads—no cross-threading, no galling, no thread damage.
-
Seal engages: The floating piston positions the internal seal against the fitting face or ID sealing surface. The seal is pressure-assisted: as test pressure increases, the seal force increases proportionally.
-
Test: The FasTest 60 is locked and sealed. Run the test—pressure decay, leak test, proof test, or filling—with confidence that the connection is secure.
-
Pull off: After depressurizing, pull the sleeve back to retract the collet and lift the connector off the fitting. The optional internal shut-off valve closes automatically upon disconnection, stopping flow for clean operation.

Where the FasTest 60 Is Used
Automotive & EV Manufacturing
The FasTest 60 is the most commonly specified external thread connector in FasTest Engine Packages. It seals to oil drain ports, coolant ports, sensor locations, and other external threaded connections on engine blocks, cylinder heads, transmissions, and powertrain assemblies. On EV platforms, it connects to coolant circuit test points on motor housings and battery enclosures.
HVAC-R Component Testing
The FasTest 60 connects to threaded fittings on compressors, valves, manifolds, and piping assemblies during coil leak testing, system processing, and assembly verification. The optional internal shut-off valve is particularly popular in HVAC-R applications where refrigerant containment during disconnection is important.
Fluid Power & Hydraulics
Hydraulic hose assembly proof testing is one of the highest-volume applications for the FasTest 60. It grips JIC swivel nuts and ORFS fittings instantly—replacing the wrench-on connections that slow down hose test lines and damage fittings. Valve body, manifold, and pump testing also rely heavily on the FasTest 60 for external threaded port connections.
Aerospace
The FasTest 60 connects to AN and aerospace-specification external threaded fittings for tube assembly leak testing and proof testing. The collet’s non-damaging grip is critical on aerospace fittings where thread damage can scrap flight-critical components.
Appliance, Medical, and General Manufacturing
Any production environment with external threaded ports that need fast, repeatable, non-damaging test connections benefits from the FasTest 60. From appliance plumbing and gas connections to medical device threaded ports to general industrial testing, the FasTest 60 is the default choice for external thread sealing across FasTest’s entire customer base.
