Key features

FITS: Universal AS568-237 o-ring size | Nominal 3 3/8" ID x 1/8" CS | Actual 3.359" ID x 0.139" CS (tolerance ±0.024" ID / ±0.004" CS, 3.637" OD) | Replaces any standard dash-237 70A o-ring across pumps, valves, filters, gearboxes, hydraulics and plumbing.
WHAT YOU GET: 5 o-rings, precision-molded to the AS568-237 standard and inspected for finish and dimensional accuracy. Durometer 70A. Lubricant is not included; see our Pro Tip below.
BUILT TO LAST: Buna-N (nitrile) resists oil, fuel, water and abrasion, holding a tight seal in most pump, valve and hydraulic service. Molded from virgin compound for consistent squeeze and long service life.
DIY-FRIENDLY: Drop-in replacement — no special tools required for most o-ring changes. Clean the groove, seat the ring, and lubricate before assembly. Backed by Beaver Island Parts Company, an American family-owned small business.
PRO TIP - USE WITH AQUA FLEX LUBRICANT: Before install, coat the rubber with Aqua Flex lubricant, formulated for pool, spa and equipment seals, to ease seating and extend seal life. Search "Aqua Flex" on Amazon.
