Grease Fittings and their accessories

Grease fittings (or grease nipples, Zerk fittingsgrease zerks, Alemite fittings, Zerks) are lubrication points in mechanical systems that add grease from grease guns. By applying pressure to a ball valve in the fitting, grease flows into the lubricating chamber, but cannot flow out.

Grease fittings come in different sizes, threads, lengths, adaptations and styles. Below we'll discuss the common characteristics and the more important things to know about grease fittings and their accessories.

Grease fitting (Zerks) styles

If you need SAE or metric zerks we've got a collection in packages of 5 and 10, and in kits, offering: straight, 45, 65  and 90 degree angles in any size you might want.

Grease Fitting Unblocker (Professional)Grease fitting unblocker - professional

The Unblocker opens clogged grease fittings and loosens hardened grease joints

The Grease fitting Unblocker removes old hardened grease, dirt and debris from clogged up bearings. Simply changing the fitting in most cases does not fix the issue, because the blockage is most often located in the joint itself.

The Grease fitting Unblocker has an all steel construction and works by injecting a light viscosity oil into a grease-joint through pressure, generated by the tap of a hammer. Hereby liquefying the old grease or dirt, and forcing it out the other end of the joint. Once the clog has been removed, simply grease your joint as normal, using your grease gun.

The Grease Fitting Unblocker comes complete with grease coupler for connection into the grease fitting and hose for hard to reach fittings.

 

Drive Fit – Grease Fitting Installers

Handy grease fitting drive tools make installing straight and angeled drive type fittings and zerks easy. Insert a drive tool over the fitting and tap opposite end with a hammer to seat.

The tools are made of heavy duty steel with a zinc-plated finish.

Available in 2 types: straight and angled
