CMP Self-Sealing Union, 1½" MIP × 1½" Socket | 21063-170-000

21063-170-000: 1½-inch male pipe thread (MIP) × 1½-inch socket; standard straight configuration. Nominal connection size does not specify outside dimensions or overall length.

One union assembly. Pipe, equipment and additional fittings are separate purchases. Manufacturer carton counts are bulk shipping quantities, not this individual selling unit.

Match the actual mating connection and the complete configuration. A matching nominal pipe size alone does not confirm fit to a particular pump, filter, heater or other assembly.

Follow the fitting and connected-equipment instructions. Match thread form, connection size, union halves and available clearance. This listing does not derive numerical temperature or pressure limits from a size or product-family name.

CMP’s cross-reference table lists 150-903. These are manufacturer comparison references, not a claim that every pump or heater using the nominal size accepts this union. Verify the complete connection and configuration.

CMP’s standard limited warranty provides one year from original purchase for defects in materials and workmanship unless otherwise noted, subject to exclusions and claim requirements. The linked manufacturer statement limits its scope to the United States; confirm destination-specific terms for use elsewhere.
