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.

Straight 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.

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.

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.

Grease Dispensers

Plastic

Bowl

A spring delivers a constant, low-pressure flow of grease to your lubrication point, so it never runs dry. They’re best for applications with consistent temperatures, so the viscosity of the grease won’t change how quickly it flows. However, they shouldn’t be used in precision applications because the tension of the spring may change, causing the dispensing rate to change. Mount them close to the lubrication point. They have a standard grease fitting, so you can choose what grease to use, unlike prefilled dispensers. The grease fitting helps close the system to keep out dust and contaminants in dirty environments such as mills. Use grease fitting adapters to match your lubrication point.

Plastic Bowl—Clear—Dispensers with a clear plastic bowl make it easy to see how much grease is left and whether the dispenser is working properly. These dispensers come with three different adjustment springs to fit your dispensing needs.

Plastic Housing—Plastic housings are an economical choice when there's minimal vibration.

Anodized Aluminum Housing—Anodized aluminum housings withstand vibration, shock, and impact.

Nickel-Chrome-Plated Aluminum Housing—Nickel-chrome-plated aluminum housings resist corrosion better than plastic and anodized aluminum dispensers.

Remote-Mount Springs—Remote-mount springs (sold separately) provide extra pressure when using thick grease at a distance.
