    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.

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

    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.

    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 adapters have mild corrosion resistance.

    Grease Fittings for Unthreaded Holes

    Drive these fittings into unthreaded holes with a hammer and grease fitting installation tool (not included). They're also known as hydraulic grease fittings.

    Fittings with a serrated shank have a tighter grip than those with a smooth shank for a more secure fit in old or oversized holes.
    Zinc-Plated Steel—Zinc-plated steel fittings have mild corrosion 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.

    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.
