Measure your old ring first

Seal sizes vary by brand and by model year. Lay your old ring flat and measure the inside diameter and the thickness: it should be close to 2.609 in x 0.139 in. Old rings stretch or swell a little, so expect a small difference.

Wipe the groove clean and apply a thin film of silicone O-ring lubricant before fitting. Never use petroleum grease on a Buna-N ring.

Buna-N is the standard material for pump lids, unions, valves and filter tanks. Chlorinator and chemical feeder lids need a Viton (FKM) ring instead.
