GREAT WALL Stainless Steel Straub Coupling with Copper Anchoring Teeth is high performance coupling suitable for varied pipe systems. 
Our Coupling provide Axial Restraint for Pipe Connection . 
Our straub couplings used to join Metal Pipe to Metal Pipe or Metal Pipe to Plastic Pipe or Plastic Pipe to Plastic Pipe .
They are mainly used for building construction or civil engineering, power plants and etc .
This pipe joining coupling absorbs unexpected field stress and applies perfect for seismic retrofits 
All of our Coupling designated with GRIP have axial restraint .
In order to able to absorb the axial forces arising from the internal pressure, 
anchoring teeth engage in the relevant pipe materials and provide a mechanical frictional connection.
If the axial tensile load on the pipe increases due to increasing internal pressure, 
the teeth engage deeper inot the pipe surface .
 These flexible and lightweight Couplings come fully assembled and can be installed without using any special tools .

1. Briefs :
