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.

90° Elbow with Male Thread

SAE-LT Thread—SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.

PTF-SAE Thread—PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads.

UNF Thread—UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.

Zinc-Plated Steel—Zinc-plated steel fittings have mild corrosion resistance.

Brass—Brass fittings resist corrosion better than zinc-plated steel fittings.

303 Stainless Steel—303 stainless steel fittings are more corrosion resistant than brass fittings and have good chemical resistance.

316 Stainless Steel—316 stainless steel fittings resist corrosion and chemicals better than 303 stainless steel fittings and can be used in saltwater environments.

Ball Check Valve—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.

Leakproof Grease Fittings

Keep thin grease from leaking out—the check valve in these fittings has a Buna-N seat that creates a tighter seal than check valves in other grease fittings. The valve stays closed when not in use to keep out dirt and other contaminants. Fittings are zinc-plated steel, which has mild corrosion resistance. They're also known as hydraulic grease fittings. They have PTF-SAE and NPTF (Dryseal) threads, which are compatible with NPT threads.

Self-Tapping Grease Fittings for Unthreaded Holes

To fit securely in unthreaded holes, these fittings cut threads as they’re installed. Use a hex wrench to install. Fittings can be driven in, but then are not pressure rated. They're zinc-plated steel for mild corrosion resistance. All have an integral 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. These fittings are also known as hydraulic grease fittings.
