The ASHLAND WATER GROUP WSFC150 is a flush inside slip coupling designed for 1.5-inch PVC pipe. Unlike a standard slip coupling, this fitting is engineered to seat flush inside the pipe ends, making it well suited for repairs where external coupling shoulders would obstruct pipe movement or clearance. The body is PVC construction, offering chemical resistance and durability in both pressure and non-pressure piping systems. Plumbers and pool service technicians install this fitting during pipe repair work where a traditional coupling cannot be used due to space or access constraints.
This coupling is used in residential and light commercial plumbing, irrigation, and pool or spa piping systems that run 1.5-inch PVC pipe. Its flush inside design eliminates the need to cut additional pipe length to accommodate a standard coupling shoulder, making it particularly useful in tight repair scenarios where pipe movement is limited. It is sold as a unit of measure of each (EA), with a package quantity of 4.
Designed as an OEM-style replacement fitting for standard 1.5-inch PVC slip-joint piping systems used in plumbing, pool, spa, and irrigation applications.
Installation is performed by licensed plumbers or qualified pool and irrigation technicians. Shut off all water supply and relieve system pressure before beginning any pipe repair. Solvent-weld connections require properly prepared, clean, and dry pipe ends with the appropriate PVC primer and cement per manufacturer and local plumbing code requirements. Follow IPC or local code guidelines for allowable fittings in pressurized systems.
