CMP Union Tailpiece, 1½" Buttress Thread × 1½" Socket | 21046-000-000

21046-000-000: 1½-inch buttress thread × 1½-inch socket; tailpiece only configuration. Nominal connection size does not specify outside dimensions or overall length.

One union tailpiece only. A union nut, gasket, mating half and complete union assembly are not included.

Match the 1½-inch buttress union thread and 1½-inch socket to the actual mating assembly. Buttress union threads are not ordinary NPT pipe threads; a nominal-size match alone does not establish interchangeability.

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 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.
