Pump unions make pump service possible without cutting plumbing, but the union must match the pump and pipe connection style exactly.

The Carvin/Jacuzzi Self-Aligning Pump Union [1-1/2" Slip / 2" Spigot] [Qty 2] (31158603R2) is a two-piece union set designed to help align compatible Carvin and Jacuzzi pump connections during installation or replacement.

Self-aligning unions are especially useful where plumbing is slightly offset or where old unions have become brittle, cross-threaded, or unable to seal with a new pump installation.

Replacing both unions at the same time can help prevent leaks, reduce installation frustration, and create a cleaner serviceable connection around the pump.

  • Self-aligning union design for compatible pumps
  • 1-1/2 inch slip / 2 inch spigot reference
  • Includes quantity two pump unions
  • Useful during pump replacement or re-plumbing
  • Helps create leak-resistant service connections
