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

Comprehensive 110-Piece SAE Grease Nipple Assortment for Machinery & Equipment Maintenance

This 110-Piece SAE Grease Nipple Assortment provides a complete selection of straight, 45°, and 90° grease fittings (also known as Zerk fittings or Alemite fittings) to support maintenance on a wide range of mechanical systems and industrial machinery. Packed in a multi-compartment storage case, this kit keeps fittings organized and ready for quick access in the shop, field, or service truck.

Grease fittings serve as essential lubrication points on bearings, shafts, linkages, chassis components, and rotating equipment. Their design allows grease guns to securely couple to the nipple and deliver grease precisely into lubrication channels while preventing dirt and contaminants from entering the system. With a proven legacy dating back to the 1920s, Zerk fittings remain standard in manufacturing, automotive, heavy equipment, agriculture, and industrial machinery.

This assortment includes the most commonly used SAE sizes and angles, ensuring technicians always have the correct fitting for replacement, repair work, or new installations.
