Ralston Instruments Quick-Test microbore hoses provide a fast, low volume, high pressure way of connecting to your pressure instrumentation, hand pump, calibration source or device under test.

Quick-Test hoses can be attached and detached without a wrench or thread sealant, while maintaining a working pressure of 6,900psi / 475 bar. A burst pressure rating of 27,000psi / 1,860 bar ensures safety and reliability in the field.

With a minimum bend radius of just 26mm and a reinforced Polyamide inner core to prevent kinks and bends from changing volume, these hoses are flexible, tough and engineered to maintain stable pressure regardless of twists and turns.

A small inner diameter of 3mm is ideal for transmitting instant high pressure to your device under test while consuming very little compressed gas or fluid.

A reflective outer cover reduces temperature sensitivity in operations from -40°C to +60°C.

A wide variety of interchangeable Ralston Quick-Test adapters provide connections for almost any application.
