Chelsea O-Ring 28P289 or 28-P-289 is a power take-off seal ring with a .864 inside diameter and a .070 cross-section thickness. This small round seal fits within Chelsea PTO assemblies, where it seals against fluid leakage at a gasket or mating surface. It is a service-replacement wear item, commonly swapped during PTO repair or rebuild to restore a clean seal. Sold by Pro Gear and Transmission as a genuine Chelsea part. Because it is a tiny seal that is easily mis-ordered, give us a call to confirm it matches your PTO model before you order.
