Product Name: Single Trench High Pressure Corrosion Resistant Quick Couplings

Product information:

The single groove pipe clamp coupling is composed of two shells, a sealing rubber ring, two bolts and nuts.

The rubber seal ring located in the inner layer is placed on the outside of the connected pipe and fits with the pre-rolled groove, and then buckle the clamp on the outside of the rubber ring, and then fasten it with two bolts.

Single grooved pipe clamp is used for general pipe joints that require rigidity and can provide a fully rigid connection.

Compared with the flange connection, the single groove coupling is lighter, the installation steps are reduced, and the safety performance is increased. Therefore, the coupling can almost completely replace the flange connection.

Product attribute:

--Grooved joint


--Ductile iron

--Sealing ring:Silicone rubber, butadiene rubber, EPDM
