Chengming Hydraulic Co., Ltd. pressure test connectors are equipped with a self-sealing valve. When used individually, the valve closes due to the action of the spring. After connecting to a measuring hose or connector with a mandrel, the self-sealing valve can be opened for sampling and system pressure detection in high or low-pressure fluid systems.

Advantages of Pressure Test Fittings:

1. Simply connect or disconnect the soft measuring hose with your hands under high pressure

2. Easy connection with the same gauge

3. Compact structure

High work pressure

Pressure Test Fitting Material:

Metal Part: Carbon Steel or Stainless Steel 316TI

Sealant: Carbon Steel Fitting with Nitrile Rubber (NBR) (-25°C — +90°C)

Stainless steel fittings with FPM fluororubber (-20°C to +200°C).
