O-RingThis O-ring is an aftermarket replacement static seal for a hydraulic, fuel, or pneumatic joint on a forklift. Service techs replace O-rings at every disassembly because preload is lost after first compression and reused seals weep under operating pressure. Sized inventory by application reduces callbacks for slow leaks at fittings. Sold as an aftermarket replacement, contact us to verify size and compound before ordering, since visually similar O-rings differ in material formulation, and substituting between Buna, Viton, and EPDM in incompatible service environments leads to swelling, hardening, or extrusion of the seal from the groove during operating service.Aftermarket replacement part, cross-references original part number AC0350-00240.Need help confirming fit?
