CMP Union Kit [2", Nut/Sleeve/T-Gasket] is a union repair or replacement kit for compatible pool and spa plumbing connections. Union components make it easier to disconnect equipment for service while maintaining a sealed connection when reassembled. A correct kit can restore a worn nut, sleeve, or gasket without replacing more of the plumbing than necessary. Verify the listed size, included components, fitting style, and part number 21023-000-000 before installation to help avoid leaks or mismatched threads.

For best results, compare the replacement against the original part before disassembly is complete. Pay close attention to size, rating, connection, and model details shown in the title, because those details are usually what separate a correct repair part from a part that appears similar but will not install correctly. This product is intended for service and maintenance work where dependable fit matters more than guesswork, and it is especially helpful for technicians or homeowners trying to repair existing equipment instead of replacing a full assembly.

  • Union service kit for compatible pool and spa plumbing connections.
  • Includes the connection components described in the product title for targeted repair.
  • Confirm part number 21023-000-000, size, thread style, and gasket design before ordering.
  • Helps restore a removable service connection without replacing excess plumbing.
  • Tighten evenly and check for leaks after the system is pressurized.
