About Oil Fittings and Oil Cups

Oil Fittings for Unthreaded Holes
Drive these fittings into unthreaded holes.
Zinc and zinc-plated steel fittings have mild corrosion resistance. Nickel-plated steel fittings are more corrosion resistant than zinc and zinc-plated steel fittings.
Fittings with a check valve prevent oil from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants. Fittings with a self-closing hinged cover block contaminants from entering equipment.
Note: Fittings do not hold oil; any oil dispensed into the fittings passes into the part to be lubricated.

Oil Fittings
Zinc and zinc-plated steel fittings have mild corrosion resistance. Zinc-plated brass fittings have good corrosion resistance. Nickel-plated brass fittings are more corrosion resistant than zinc-plated brass fittings.
Fitting with a check valve prevents oil from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants. 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.

Oil Cups
A built-in reservoir allows oil to gradually pass through to equipment, reducing time spent on manual lubrication. Flow rate depends on temperature.
Use 90° elbow cups for side-mount applications and where vertical space is limited.
Oil cups with wick feed have a wick that extends through the threaded connection of the cup and keeps the bearing dust-free and lubricated, even after the oil cup is drained.
