Grease Fittings & Lubrication

Grease fittings are installed into mechanical systems to supply grease to components in need of lubrication. They are usually fitted to parts via a tapered thread or push-fit, allowing lubricant to be squeezed under pressure into bearings with a grease gun or other lubrication mechanism. Once grease has been applied, the grease fitting prevents it from escaping from the bearing.

Grease fittings are manufactured in a range of materials, including brass, stainless steel, and monel nickel-copper alloys.

Grease fittings can be found in various industrial, agricultural, mining, aerospace, and automotive applications. Huyett supplies a comprehensive range of grease fittings and machine lubrication accessories from brands that include Alemite, Handi-Chek, Heritage Industrial, Lincoln, and more.
