These pressure gauge cutting ring compression fittings are usually used for mounting of pressure gauges and other hydraulic equipment. 

We have constructed very thoroughly the pressure gauge fittings with cutting ring. The twin Biting corners of the cutting ring form a strong and secure grip on the tubing to provide leak-free link of tubes and elements in fluid structures.

Using these pressure gauge connectors, the connecting line can be executed with a steel tube (outside dia. 8 mm ) but preferentially, a test hose with the fitting “D” can be used.

While standard fittings can be used as well for adapters for the hydraulic connection, the offered pressure gauge cutting ring fitting has been designed specifically to allow fixing it, by counter nut, to a mounting bracket.  Therefore It is used mainly for pressure gauges with radial connection ports.
