Ralston Tube Fitting Quick-test Adapters
Connecting to tube fittings with a wrench takes time, and repeated tightening can damage fittings and cause leaks.
Ralston Tube Fitting Quick-test Adapters connect in seconds using only your fingers, creating a gas-tight, leak-free seal without tools or thread tape.
They are compatible with most major tube fitting brands, including Parker, Swagelok, Tylok, and SSP, helping improve efficiency across a wide range of calibration and testing applications.
Choose the right adapter for your application.
