Cub Cadet 721-3021

O-Ring, .301 ID X .070 OD
(Superseded to 921-3021)
Description... Hide
The purpose of the O-Ring is to seal connections in pipes and tubes for fluids. The O-Ring is a gasket in the form of a ring, commonly found in rotating pump shafts and hydraulic cylinder pistons. O-Rings can wear over time from abrasion, friction, improper lubrication, and high pressure. Your O-Ring may be damaged if the contact faces have a grazed surface, lacerations, and breaks. Because O-Rings must be the proper size to create a seal, we recommend O-Rings are purchased from the OEM/Manufacturer.
