Ralston Quick-test Hoses

Ralston Instruments Quick-test™ hose is unique because it 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.
