About Grease Fitting Threads
More
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. Brass fitting is more corrosion resistant than zinc-plated steel fittings.
