This Grooved Rigid Coupling is used in fire suppression systems, thus allowing water to flow easier and allowing for inflexibility in the joint. A pad is included with the purchase of this product. It is constructed of rubber polymers with low compressions set properties. Pads help form an initial seal as it is stretched over the pipe ends and creates a leak proof seal. The Coupling helps insure this seal once installed.
