What Are Grease Fittings?

Grease fittings are small, precision-machined components that allow grease guns to inject lubricant directly into bearings, joints, and other moving parts. They create a sealed lubrication point, preventing contamination while enabling maintenance teams to deliver grease exactly where it’s needed.
 

Types of Grease Fittings We Offer

  • Straight Grease Fittings — standard fittings for easy-access lubrication points

  • Angled Grease Fittings (45° & 90°) — for hard-to-reach or tight-space applications

  • Drive-Type Grease Fittings — hammer-in style for thin-walled or untapped holes

  • Threaded Grease Fittings — NPT, metric, and UNF threaded options for secure installation

  • Button Head Grease Fittings — for heavy-duty equipment and large-volume grease applications
