Coupling - Blueline FRPP No Hub

Blueline FRPP No-Hub Couplings are used to join Blueline FRPP pipe and fittings when using the No-Hub mechanical joint method. No-Hub is an economical, fast, and easy method that requires torquing to 60 in-lb. Its 300 series stainless steel outer coupling and plated 5/16 inch bolts create tight, leak-free, and reconfigurable joints in chemical waste drainage applications such as laboratories in schools, universities, and research facilities. Blueline FRPP is molded from proxylene blueline resin, a flame retardant thermoplastic material with excellent resistance to most common and organic mineral acids and their salts, strong and weak alkalis, and most organic chemicals. Couplings are available in 1-1/2 in., 2 in., 3 in, 4 in., and 6 in. sizes.
