Safety Vent Fittings
Safety Vent Fittings for Ventilated Grease Application
Safety vent fittings, or safety grease fittings, are visually similar to standard grease zerks but have the added benefit of a milled slot up the side of the threads. The milled slot is an integrated safety feature that allows air to escape while grease is applied to a mechanical component. The slot also serves as a visual indicator, as grease will flow out when enough has been applied to avoid a buildup of pressure; it also allows for the flow of air for ventilation.
These fittings are just one of several types of
grease fittings, (also called zerks, grease zerks, or zerk fittings). Zerks are designed to lubricate mechanical applications that require oil or grease, like agriculture machinery or machine components. They are typically found in agricultural equipment, automotive applications, and similar settings Other types of fittings include:
- Standard Grease Fittings: The most common design; compatible with most couplers.
- 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.
- 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.
- Flush Fittings: Low-profile shape with a concave head that also minimalizes interference with other parts.
- Ball-Type Fittings: Reduce the risk of back flow.
Product Benefits
Safety vent fittings offer the following benefits:
- Ventilation: The side slot allows grease and/or air to escape the application, avoiding excessive pressure and reducing the risk of damage.
- Versatility: These fittings are compatible with standard hydraulic grease gun couplers, simplifying installation.
