O-RingThis Anderson aftermarket O-ring, AC1015530, is a round elastomer seal used at static and slow-moving sealing surfaces throughout a forklift's hydraulic, fuel, and cooling circuits. Mechanics replace O-rings any time a joint is opened — reused O-rings take a compression set and may not reseat reliably. Buyers are typically independent forklift shops, hydraulic rebuilders, and PM techs who stock common O-ring sizes by box. Anderson supplies it as a direct aftermarket replacement. Verify inner diameter, cross-section, and material (typically Nitrile or Viton) against the original before installing in a hot or fuel-wetted location.Aftermarket replacement part, cross-references original part number AC1015530.Need help confirming fit?
