Safety Grease Fittings

Safety vent fittings, or safety grease fittings, are visually similar to standard grease zerks but with the added benefit of a milled slot in 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 aid as grease will flow out when enough has been applied.
