Description
This replacement O-ring is designed for 1 1/2" heater unions and measures 1 7/8" center to center. Engineered to fit the 1 7/8" groove found on most standard 1 1/2" heater unions, this seal creates a watertight connection between your spa heater and union. Please note that some models may require the 2 1/8" center to center version instead - we stock both sizes at Global along with 1 7/8" O-ring style gaskets for your convenience. Compare the product images carefully to ensure proper fitment. This component serves as the critical sealing element in your hot tub's heating system. IMPORTANT: This listing is for the O-ring seal only. Additional components shown in photographs or instructional videos are displayed for reference purposes and are not part of this purchase.90-423-5224,14-110-2000 , 191474 , 224 , 224-7470-10 , 31240
