Hoses
Ralston Quick-test and microbore hoses for pressure calibration — QT, XT, Male NPT, medium-pressure, tube QC, AN flare, and related assemblies.
Choosing a hose
- **Pressure rating** — stay within the printed working pressure for the media you use.
- **End connections** — Quick-test, NPT, AN, tube QC — match your adapters and UUT.
- **Length and flexibility** — shorter for bench; longer for awkward field UUTs.
- **Media compatibility** — pneumatic vs hydraulic; avoid contamination into dry gauges.
Quick-test advantage
Ralston Quick-test ends connect without tools and seal with a finger-tight make-up, which speeds gauge and transmitter changeouts during as-found / as-left work.
Pairing
Hoses pair with **Pumps & Generation** and **Fittings & Adapters**. Product pages list OEM-compatible ends where known.
Note
Hoses are not calibrated instruments; keep them clean and within rating, and calibrate the reference gauge or calibrator.
