PLASSON STAINLESS STEEL GRIP RING FOR PVC

Before installation ensure that the end of the pipe to be inserted into the fitting is free of scratches and other imperfections and that both the pipe and the fitting itself are clean of sand, mud, stones etc. Do not over tighten nut when closing. Never use wrenches or spanners with handle lengths longer than 46 cm - excessive torque during tightening can spread nut cone and result in pull outs. If fittings are reused, ensure split ring is sharp and bites into pipe to avoid pull outs. Alternatively replace split ring. Pull out resistance of Series 7 fittings combined with the UPVC/PP grip ring has been approved by pressure testing UPVC/PP pipe assemblies at 25 bar operating pressure for at least 1 hour. Note: We strongly recommend the use of PTFE tape in threaded connections.
