    NPTF Thread and PTF-SAE Thread—PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads.
    SAE-LT Thread—SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.
    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 and Plunger 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.

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

    Button Head Grease Fittings

    Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won’t pop off when adding grease. They're best for machinery requiring high volumes of grease because they let more grease pass through than standard grease fittings, thanks to a larger opening. 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.

    NPTF Thread and 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.
    303 Stainless Steel—303 stainless steel fittings are more corrosion resistant than zinc-plated steel 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.

    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.

    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.

    Pressure-Venting Grease Fittings

    To protect equipment from damage, the slit in the threads of these fittings acts like a breather vent, releasing any excess pressure and grease. You’ll know your fitting is properly lubricated if you see any grease come out of this slit.

    Flush-Style Grease Fittings for Unthreaded Holes

    Since they don’t protrude, these fittings avoid damage from impact and fit in tight spaces. Use a hammer and grease fitting installation tool (not included) to drive them into unthreaded holes. 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.

    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.

    Self-Tapping Flush-Style Grease Fittings for Unthreaded Holes

    Image of Product. Front orientation. Grease Fittings. Self-Tapping Flush-Style Grease Fittings for Unthreaded Holes.
    Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use them in tight spaces where protruding fittings won't work. Install with a hex wrench. Fittings can be driven in, but then are not pressure rated. They’re zinc-plated steel for mild corrosion resistance. 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.
