suitable for potable water,neutral liquids and sewage
WRAS ,ACS,DVGW etc approved is available
Coating standard EN30677
Test standard EN12266-1
Wide tolerance range
Corrosion resistant construction
Total angular deflection of ±4°
Flange drilling with BS4504 EN1092 or ANSI Standard
GD8.8,stainless steel bolts nuts and washers
various coating
Seal:NBR ,EPDM etc
Precaution
Ultra grip coupling can’t accommodate for AC(Asbestos cement) pipe and GRP pipe.Because AC pipe surface is too rough ,the griper of ultra grip coupling can’t work properly.GRP pipe is very smooth, can’t offer enough friction for the griper.
Note
The stainless steel gripper is specially designed for HDPE pipes. When connecting to other types of pipes, the stainless steel gripper should be removed to avoid affecting the sealing.
Use
Both ends can connect pipes with the same outer diameter or different outer diameters at the same time, as long as the design range of Mechanical Coupling Joint includes the outer diameter of the pipes
