Grease Fittings

Grease Fittings

Provide permanently installed lubrication points on critical machining parts with these grease fittings, also known as Zerk fittings or grease nipples. A ball and spring keep contaminants out of the fittings, and when a grease gun is used, the ball is displaced, allowing for the flow of grease.

For Untapped Holes

Save time and money on tapping holes with these fittings. They include fittings that can be driven into an untapped hole using a hammer and a grease fitting tool as well as fittings with self-forming threads that cut their own threads as they are installed.

Leak Proof

Use a leak-proof fitting to prevent grease leaks and promote safety. The heat-treated springs stop lubricants from escaping.

High-Volume Button Head

When your application requires high-volume flow, these button head fittings provide lubrication points for large quantities of grease. They're commonly used on conveyors, mining equipment, and earth moving machinery.

Low Profile

Also known as flush fittings, these fittings don't project above the mounting surface for use in tight spaces and low-clearance applications.

Pressure Relief

Commonly used with bearings and grease housings, these fittings open at a preset pressure to safely relieve pressure built up from operation or excessive lubrication.
