Test coupling

Hydraulic Test coupling (PT type & PF type) 

Feature

A test coupling, the semi-automatic typed product is remained shut in the normal operation but opens by its poppet being depressed when a gauge or a hose is connected for a test.

It makes pressure test on the hydraulic circuit and ventilation easy. By fitting at the fore part of a gauge, it can be used to block pressure automatically in case of the gauge being out of order and consequently removed.

It has PF type (G ; ISO 228-1) and PT type(R ; ISO 7-1).
