This replacement gasket works exclusively with 2 1/2" pump unions featuring approximately 3 5/8" inside thread measurements. Precision-engineered dimensions include 3 1/4" outer diameter, 2 3/8" inner diameter, with a 2 7/8" center-to-center lip specification. As the fourth most commonly needed pump union gasket size in the spa industry (following 2", 1 1/2", and 1" variants), this seal component creates a watertight connection between your hot tub pump and its union fitting, preventing leaks and maintaining optimal system pressure.
