LUBRICATION NIPPLES

Grease fittings, also referred to as grease nipples, Zerk fit tings, or Alemite fittings are found on mechanical systems and machinery and serve as lubrication points for bearings or other mechanical components. With a history dating back to the 1920s, grease fittings still find widespread use today. Their unique design provides a secure connection between the nipple and grease gun coupler to allow for the precise delivery of grease while preventing against contamination. Grease fittings are available in a variety of shapes to fit any application.
