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, pressure test coupling, or Minimess 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…

There may be times when you want to check your hydraulic system’s pressure but the test connector is too close to a moving part, making the task too dangerous. Or perhaps you might want to sit in the operator’s seat of a piece of mobile equipment to monitor the machine’s performance. Either way, the microbore hose assembly is designed to make remote pressure observation safe and convenient.

Measuring approximately 1/4″ (5mm) in diameter and extremely lightweight, microbore hose is available in various lengths for your convenience and connects to any STAUFF® Test 20 (M16x2) test point. A hose union is required to connect a microbore hose assembly to a direct gauge adaptor.

A microbore hose (spaghetti hose) is a critical component in pressure testing applications, offering unparalleled precision and reliability. Specifically designed for high-pressure fluid transmission, this hose features a small internal diameter that ensures accurate and consistent measurements during pressure tests. Ideal for industries such as aerospace, automotive, and manufacturing, the microbore hose is essential for validating system reliability under specified pressure conditions. Crafted from durable materials, this hose provides superior resistance to corrosion, chemicals, and extreme temperatures, making it highly reliable in harsh environments. Its compact size allows for precise readings with minimal fluid displacement, which is crucial for accurate pressure testing.

PD Series diagnostic couplings provide easy connections for mechanical gauges or specialized diagnostic equipment. Typically, PD nipples are permanently mounted in the system at threaded test ports, in rigid tubing, or in hose assemblies. The PD nipple is used in conjunction with the PD Series test coupler. Couplers align to the mating nipples without threading. The fittings are rated up to 6000 PSI (414 Bar) depending on configuration and size. This allows gauges, transducers, and other test equipment to be snapped into place without difficulty. The design makes connecting to a PD Series test coupler, safe, effortless, and spill-free!
