The cutting ring adopts double-edged sleeve.

Generally, the surface of the joint body and the nut is galvanized. The working pressure of the joint is up to 63Mpa. The outer diameter of the seamless steel tube is up to 42mm.


Peculiarity :

- active load and double cutting ring design.

- easy to install.

- torque will not be transferred to the cutting ring during installation.

- clearance gauge ensures adequate tightening of first installation.

Double cutting ring mechanical grip design

The double cutting ring separates the sealing function from the gripping function of the cutting ring , and each them are optimized for their corresponding function.

The front cutting ring is used to form the seal: the seal between the connector body and the seal of the outer diameter of the cutting ring.
