Standard Grease Fittings
Standard Grease Fittings for Reliable Lubrication
Standard grease fittings, also known as zerks, zerk grease fittings, or grease nipples, are the most popular type of zerk and serve as lubrication points on bearing housings or other mechanical components to control the flow of grease. Their design provides a secure connection to a
standard grease gun coupler for delivering precise amounts of grease into bearings and other moving systems. The "standard" style features a conventional design, with a concentric head profile housing the nipple, a hex body, and either a threaded or drive-type shank. They are available in multiple angles (ranging from 30° to 90°), types (including aerospace, dual nipple, German thread), thread types (including PTF, and SAE-LT options), and more.
While they are the most common type, standard grease zerk fittings are just one of several types of
grease fittings designed to lubricate mechanical systems in small and industrial applications. Other types of grease fittings include:
- Hydraulic Shut-Off Fittings: Designed to shut off at a specific pressure and only reopen when pressure drops to a certain level.
- Leak-Proof Fittings: Ideal for light lubricants and work well in textile or food industry applications.
- Flush Fittings: Low-profile with a concave head to reduce interference.
- Pin-Type Fittings: Features a protruding pin that creates a positive locking mechanism with the matching pin-type coupler.
- Button Head Fittings: Features a smooth head to reduce the fitting's interference with other components.
- Ball-Type Fittings: Reduce the risk of back flow.
- Safety Vent Fittings: Ideal for applications that need to prevent overflow and/or allow for ventilation; features a milled slot that creates a space for escaping air or grease.
Several of these product lines (including standard) are also available as metric grease fittings and drive type grease fittings. If you can’t find what you’re looking for, call our Sales Team today.
