DN100 EN877 TYPE B SS304 ROUND NUT COUPLING WITH TEETH

The stainless steel couplings conform to all the mechanical requirements of DIN EN877/BS EN877. These couplings are composed of SS304 or SS 316 stainless steel shield, clamp assembly, and EPDM(An elastomeric sealing sleeve that conforms to the requirement of BS EN 681-1 and it also can resist the normal domestic effluents with thermal effects up to 70°C temperature). This elastomeric material was made with well balanced formula with a combination of outstanding properties in resisting abrasion, oil, grease, chemicals, ultraviolet, heat and cold conditions. This elastomeric sleeve also provides a cushioning element in the coupling to avoid shock, vibration and ensure a noiseless drainage system.
The stainless steel was selected for the clamp and shield assemblies because it possesses high corrosion resistance characteristics.
Our EN877 stainless steel coupling and grip collar are all produced using robots and fully automatic machinery. Not only do we have high production efficiency, but the quality of our products is very stable and reliable. It has been exported to many countries, such as Europe, Southeast Asia, Russia, etc. 
The standard that our products comply with:
1) DIN EN877; BS EN877;
2) EN 681-1:1996+A3:2005
