CMP Water-Stop Adapter, 1½" FIP × 1½" Socket, White | 25575-500-000

CMP’s installation diagram shows the water-stop adapter attached at the pipe end with plaster or other finish around it. This is one passive fitting for a gunite pool penetration, not an automatic fill valve.

One end is 1½-inch female pipe thread (FIP); the other is a 1½-inch socket. These are nominal connection sizes, not the adapter’s outside dimensions.

One white adapter. Pipe, separate return or light fittings, adhesive, plaster and other equipment are not included. Bulk box and bag counts do not describe this individual selling unit.

A plain water-stop ring and a pipe-end adapter serve different installation details. Match the actual connection arrangement and finish before ordering.

Use the manufacturer diagram in Resources and instructions for the connected equipment and materials. Thread-sealing products, tightening limits, adhesive selection, cure time and test procedures depend on that installation; this listing does not supply a universal procedure.

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