The health of a hydraulic system is determined by two parameters – oil temperature and pressure. Consequently, hydraulic system design engineers should install devices in the system that make it safe and simple, for maintenance technicians to check the pressure on a routine schedule.
The test point or pressure test coupling is designed for just such a task. They allow machine operators and maintenance personnel to easily and safely connect analog/digital measuring and display devices for the temporary testing or continuous monitoring of system pressure. This type of connection requires no tools, can be used during machinery operation, and will spill no oil when connected and disconnected. The unit even has the capability to connect under pressure up to 5800 PSI (400 bar).
The pressure testing side of the test point is M16x2. The side that connects into the machinery comes in a variety of connections – NPT, SAE, JIC, Metric, BSPP, BSPT, ORFS, DKO, etc. A benefit of using…
