O-RingThis O-ring seals a static joint on a forklift hydraulic, fuel, or pneumatic circuit. Service techs install fresh O-rings at every disassembly because preload is lost after first compression and reused seals leak under operating pressure. Stocking sized O-rings by application reduces parts-counter delays and prevents shortcuts where a tech might gamble on a reused seal. Sold as an aftermarket replacement, contact us to verify dimensions and material compound before ordering, since visually similar O-rings vary in chemistry, and substituting between Buna, Viton, and EPDM in incompatible service environments leads to premature seal failure within a few service hours.Aftermarket replacement part, cross-references original part number AC0350-00160.Need help confirming fit?
