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.
Brass fittings resist corrosion better 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-SAE and NPTF (Dryseal) threads are compatible with NPT threads.

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-SAE 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.

Grease Fitting Adapters
When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
Brass adapters resist corrosion better than zinc-plated steel adapters. PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.

Remote-Access Grease Fittings
Access difficult-to-reach lubrications points from up to 10 ft. away. These fittings are made of brass, so they resist corrosion. 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.
Cut the included tubing to your desired length before attaching fittings.

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. 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.
