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.

Adapt to Any Situation

Quick-connect to Existing Fittings
Equip your Ralston Quick-test™ high pressure hoses with quick-connect adapters for direct connection to Male or Female NPT, BSPP, Tube Fittings, Metric, AN 37° Flare and CGA 580 fittings—without wrench or thread tape.

Integrated Check Valve

Ralston Quick-test™ pressure hose fittings and adapters are also available with integrated check valves for testing live-pressure systems.

Disconnect Safely Under Pressure

The Ralston Quick-test™ pressure hose connectors can vent pressure while still connected for safe disconnection without hoses whipping around.

Preserving your Reference Device Investment

Repeated wrenching on high quality references can wear out threads and cause a loss of calibration. Adapting your references to a Quick-test™ connection to protect your investment while speeding up the calibration setup process.
