Description
This dual gasket package includes both standard 2 inch heater and pump union gasket sizes in one convenient kit: one gasket featuring a 2 1/2 inch lip measurement (center to center) and one gasket with a 2 5/8 inch lip measurement (center to center).
Perfect solution when you're uncertain which gasket size your spa requires - simply install the correct fitting gasket and keep the other as a spare or discard it.
First Gasket Specifications: Outer diameter measures 2 7/8 inches, inner diameter approximately 2 3/16 inches, with a 2 1/2 inch center to center lip designed to fit into most union fittings (some exceptions apply, so measuring is recommended). Should the ridge not fit your particular union, you can trim it off to create a flat gasket seal.
Second Gasket Specifications: Outer diameter measures 2 7/8 inches, inner diameter approximately 2 inches, with a 2 5/8 inch center to center lip that accommodates certain union fittings (note that most unions use the 2 1/2 inch center to center measurement).
