Advantages of air hose quick connect

pneumatic coupler air connectors for sale - JulongThe TJ793L type hose connector is an optimized design of the original TJ793 type connector, which solves the problem of the original connector wrench shaft nut falling off and the shaft Some shortcomings such as air leakage, easy to fall off of the connector sealing ring, inconsistent hardness, etc.

Inlaid o seal ring 

The connector sealing ring is embedded in the installation groove, which effectively solves the problem that the sealing ring and the plastic barrel flange are not firmly bonded and are easy to fall off.

Embedded rotating shaft nut 

The handle shaft nut is embedded in the connector wall, which not only fundamentally solves the problem of the penetration bolt shaft screw loosening and falling off, but also the connector wall is smooth and the sealing effect is better.
