Repeated wrenching on high quality references and precision fittings can wear out threads and cause a loss of calibration or damage to the equipment. Protect your investment and speed up pressure testing and maintenance tasks by adapting your reference gauges and process connections to Ralston Quick-test™ fittings.
Convert standard tube fittings, NPT, BSPP and BSPT threads, pressure gauges, pressure transmitters and pressure calibrators to Ralston Quick-test™ once, and you’ll be able to connect and reconnect in seconds using just your fingers. The more pressure that’s applied, the better the seal, so you’re guaranteed to have fast, leak-free connections – every time.
