Grease Fittings
Available109 products
Grease fittings (also known as Zerk fittings or grease nipples) are permanently installed on mechanical systems and bearings to provide lubrication points for feeding lubricants to the systems or bearings without overflow or leaks. The fittings stay closed to keep out contaminants until the pressure from a grease gun forces them open to allow grease to flow to the system or bearing.
