About Oil Fittings and Oil Cups

Grease Fittings
Thread these fittings into motors, bearings, engine blocks, and other machinery to create a lubrication point. They’re also known as hydraulic grease fittings.
Zinc-plated steel fittings have mild corrosion resistance.
Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

Oil Fittings
Zinc and zinc-plated steel fittings have mild corrosion resistance. Nickel-plated brass fittings are more corrosion resistant than zinc-plated brass fittings.
Fittings with a self-closing hinged cover block contaminants from entering equipment.
UNF and UNEF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.
Note: Fittings do not hold oil; any oil dispensed into the fittings passes into the part to be lubricated.
