This 1.5” Seat Gasket is a 5 Spoke Gasket for an “X” Valve body (SPX0710XD) and fits Hayward models SP0710, 0710X, 0711, and 0712. To ensure a longer lasting gasket, make sure you always turn the valve one way. Turning it different ways can cause the gasket to be pinched which will eventually warp it. It is also very important to never lube your gasket when you install it because this will prevent a strong seal. Purchase a Hayward pool gasket today!
