Wide range sleeve ductile iron universal coupling Flexible connection dresser pipe gibault joints

Ductile iron universal dresser coupling 

Dresser coupling joint is a type of mechanical coupling

Function:it is used to join two plain ends of pipes. can grips the spigot (male end) and socket (female end) of two pipes.


Wide range of pipe diameters

The installation process is fast and simple

Not affected by the environment

No welding is required,fire hazard eliminated

Maintain the continuity of the pipeline system

can increase the hoop strength of the pipe

Allowing slight misalignment, vibration,expansion and contraction

It fits on outside wall of pipe,no internal protrusions, will not damage the pipeline lining

a length of pipe can be reomoved by disassembling the dresser coupling


One sleeve:(materials:ductile iron,carbon steel,stainless steel)

Two glands:(materials:ductile iron,carbon steel,stainless steel)

Two gaskets:also known as sealing rings(materials:Commonly used EPDM,also can NBR)

Bolts and nuts:(GD8.8,carbon steel,stainless steel,dacromet bolt)

Work pressure:PN10/PN16/PN25

Maximum temperature:-10℃~+70℃

Applicable Medium:Drinking water, neutral liquids, and sewage

Applicable pipeline materials:Cast iron pipes,ductile iron pipes,steel pipes,PVC pipes,etc

With regard to packaging, we will use plastic film to wrap the goods so as to avoid knocking off the paint. Then we will make wooden boxes for export to avoid dampness and insects, so that the goods can be delivered to customers in good condition.




Gongyi Runda Pipeline Manufacturing Co., Ltd.

Gongyi Runda Pipeline Manufacturing Co.,Ltd has its own factory and workers, customers can visit at any time.Universal coupling has a small inventory, because cast iron materials need to be made according to the diameter of the pipe through.Of course, if you need, we can send samples for you.
