Repair Coupling
The Grip-R is hinged type repair clamp, it is ideal for all situations where you need to make a permanent repair under pressure. Simply open up the coupling, wrap it around the pipe and fasten- you have repaired the pipeline such as pipe joints, cracks etc in minutes and avoided the need for costly downtime.
Suitable for pipes O.D φ26.9-φ168.3mm
Suitable for pipes material: Carbon steel, stainless steel, copper, cunifer, cast and ductile iron, GRP, asbestos cement, HDPE, MDPE,, PVC, uPVC, ABS and other material.
Working pressure up to 40bar.
The advantage of GRIP-R repair clamps is that is can befitted to existing pipes in situation, without any need to remove and replacing pipes, GRIP-R pipe repair clamp can repair the pipes that are ageing and corrosive and pipe wall has holes or cracks. When installing it, it only needs pipe clamp to wrap the leakage part and tighten the bolt. Then the installation is finished ideally and reliably.
Outside diameter of GRIP-R Folding Pipe repair clamp is from 38 to 168.3mm.
