Metric Grease Nipple Assortment – 110-Piece Zerk Fitting Kit with Straight, 45° & 90° Metric Grease Fittings

Comprehensive 110-Piece Metric Grease Nipple Assortment for Equipment & Machinery Lubrication

This 110-Piece Metric Grease Nipple Assortment provides a complete selection of straight, 45°, and 90° metric grease fittings, making it an essential kit for technicians servicing European, Asian, and metric-based machinery. Packed in a multi-compartment plastic storage case, this assortment keeps fittings neatly organized for fast access during maintenance, repair, or rebuild work.

Grease fittings—also known as grease nipples, Zerk fittings, or Alemite fittings—are critical lubrication points found on bearings, linkages, shafts, and mechanical joints. Their one-way check-valve design allows grease to be injected under pressure while preventing dirt, moisture, and contaminants from entering vital components. Despite their simple construction, Zerk fittings remain a universal standard across industrial, automotive, agricultural, and mechanical systems.

This metric assortment ensures technicians always have the correct fitting on hand, reducing downtime and keeping mechanical systems running smoothly.
