1.5" Pipe Extender PVC Fitting PEX150
1.5in. PVC Pipe Extender Insert Fitting, PEX150. Insert fitting glues inside of 1.5" PVC pipe. PVC Pipe Extenders are used in tight spaces on pool and spa plumbing, where there is no pipe to add a coupling. Pipe extenders glue to the inside of the pipe, to extend the pipe when you have to cut the pipe up against a fitting or valve. They do reduce pipe size and add some restriction, so should be used sparingly in pool and spa systems.
