Ralston Quick-test™ Microbore Calibration Hoses

Ralston Instruments Quick-test™ hoses can be attached and detached without a wrench or thread sealant while maintaining a working pressure of 6900 psi (475 bar). Quick-test hoses are small in diameter, flexible and low in volume. These hoses provide an ideal way of transmitting pressure during a vacuum or pressure calibration. A wide variety of adaptors provide a connection for most calibration applications.

Low Volume — High Stability

Create instant pressure to your device under test without wasting gas or liquid on large volume hoses. Engineered to maintain pressure regardless of twists and turns.

  • Reflective Outer Cover

    Reduced temperature sensitivity through a reflective surface.

  • Reinforced Inner Core

    Polyamide inner core prevents twisting and bending from changing the volume across the hose.

  • Small Inner Diameter

    Ideal for transmitting high pressure while consuming very little compressed gas or fluid.
