Spa plumbing: fittings, unions, and hoses

(60 products)

Find the plumbing parts you need to connect or repair your spa’s circuits: unions, fittings, hoses, seals, and assembly products. Use the measurements and part numbers for your installation to select the right components.

Check connections before ordering

  • Dimensions: Distinguish the pipe’s nominal diameter from the actual dimensions of the thread or connector.
  • Assembly: A solvent-weld fitting, barbed connector, and threaded fitting each require methods suited to their material.
  • Unions and seals: Also compare the sealing surface and the parts’ profiles. Unions with the same nominal size are not necessarily interchangeable.

See spa pumps and heaters to identify related equipment. Check what’s included and the lengths sold on each product page; allow for any clamps, seals, or assembly products required.
