Pool Unions & Union Kits

Unions let you disconnect pumps, filters, heaters and salt cells from the plumbing without cutting pipe. Shop pump union kits, heater unions, filter bulkhead unions, salt cell unions and union O-rings for Pentair, Hayward, Jandy, Sta-Rite and Raypak equipment in 1.5", 2", 2.5" and 3" sizes.

Union kits are specific to the equipment they connect to, including the thread type (buttress or standard) and pipe size. Check the part number in each listing against your equipment, or tell us your pump, filter or heater model and pipe size and we will match the correct kit.

Leaking union? Often only the O-ring needs replacing. Call 725-205-1783 and we can help you figure out which part you need. Nationwide shipping and same-day pickup in Henderson, NV.
