Pressure Calibration Fittings & Connections
Ralston Quick-test™ Connection System
No Tools. No Leaks.
Save time and frustration with Quick-test, the versatile system of pressure calibration fittings, quick connect high pressure hoses, and universal hose connectors for fast leak-free calibration connections.
Quick Connect Hoses
Low volume, quick connect high pressure hoses for pressure testing, calibration, and leak testing.
Quick Connect Fittings
Leak-free high pressure hose fittings for instant connections without tools or thread tape.
Universal Connection System
Compatible with standard process connections, gauges, pumps, and calibration references.
Low Volume, High Stability Quick Connect Hoses
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.
High Pressure & Extreme Pressure Hose Options
Standard Quicktest hoses handle up to 6,900 psi (475 bar) of working pressure
Quick-test XT hoses handle up to 10,000 psi (689 bar)
Quick Connect Fittings that Adapt to Any Situation
Cut Set-Up Time in Half
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 tools or thread tape.
Prevent Leaks & Pressure Loss
Ralston Quick-test™ pressure hose fittings and adapters are available with integrated check valves that help maintain pressure stability and prevent leaks when connecting to 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.
Preserve Your Reference Device Investment
Repeated overtightening with tools on high-quality references can wear out threads and cause a loss of calibration. Adapt your references to a Quick-test connection to protect your investment while speeding up the calibration setup process.
Standardize Device Under Test & Pump Connections
Adapt existing DUTs like transmitters, pressure switches, inline valves, and pressure pumps to the Ralston Quick-test™ system for easier expansion and quicker testing procedures.
