About Grease Fitting Threads

About Oil Fittings and Oil Cups

Grease Fittings

These fittings are also known as hydraulic grease fittings.

Brass fittings are more corrosion resistant than zinc-plated steel fittings.

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.

PTF and NPTF (Dryseal) threads are compatible with NPT threads. 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.

Pin-Style Grease Fittings

The pins on these fittings lock with dispensing tips for pin-style fittings to create a tight seal. Their brass bodies resist corrosion. They have a check valve that prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.They have PTF and NPTF (Dryseal) threads, which are compatible with NPT threads.

Zinc-plated steel fittings have mild corrosion resistance. Brass fitting is more corrosion resistant than zinc-plated steel fittings.

Remote-Access Grease Fittings

Access difficult-to-reach lubrications points from up to 10 ft. away. The fitting is brass, which is corrosion resistant. An integral check valve prevents 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-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.
