Description
This complete assembly includes everything needed: 2″ Split Nut for Heater Flange, 2″ Slip X 2″ Thread Union, matching gasket, and (2) mounting screws. The split nut fastens directly to your heater tube via the included screws, creating a secure mount that threads onto the union with the gasket creating a watertight seal between union and tube. Verify compatibility: Your 2″ plumbing should measure 2 3/8″ Outside Diameter, heater tube interior should be 2″, and the threaded section should measure 3″ Outside Diameter – if these measurements match, this is your correct replacement kit. This configuration is our best-selling size. The 1 1/2 x 1 1/2 configuration ranks as our second choice, while 1 1/2″ X 2 is third in popularity. Essential component for connecting heater tubes to unions in hot tub and spa systems.
