Ralston Instruments - Calibration Hoses & Fittings
Make a bubble-tight connection, over and over again, without a wrench.Ralston Quick-test hose and adapters seal via an O-ring and probe. The probe slides into the O-ring and provides the seal while the threads keep the probe in place. This simple and reliable method allows for leak-free connections for pressure calibration, gas sampling, pressure reading and testing.
The specialist tube fittings adapt the Quick Test system to any Swagelok, Parker, Hoke, SSP, Tylok or equivalent tube fitting. They feature a unique design that seals on an o-ring to prevent damage to a tube fitting, allowing you to make and remake the connection hundreds of times without over-tightening a tube fitting.
