Pipe Flexible Coupling

Specifications

1 Flexible coupling
2,ductile iron step coupling with FBE coated,nylon coated are available

Flexible coupling and stepped coupling,

1) Vortex manufactures many different types of ductile iron step couplings for many kind pipes(PVC/UPVC,AC,Steel etc)

We supply step couplings for all over the world and product surface shall be smooth and free from sand holes, blow holes, distortion or any other defects.

 

2) The couplings are wide tolerance product and fit all popular standard pipe sizes, thus dramatically reducing the number of product to be stocked for maintenance purposes.

 

3) The couplings are suitable for steel, PVC, ductile iron, asbestos cement, GRP, cast iron and concrete pipes. Step Couplings are designed and manufactured to fit on pipes of varying nominal bore where the pipes to be connected on either side excludes the use of the Unifit range.
