Alemite is the original manufacturer of Zerk fitting and continues to be the “gold standard” for quality. These fittings have an 1/8″ female NPT (FPT) thread, Trivalent zinc plating, and are R0HS compliant.

This fitting attaches to any 1/8″ NPT thread, standard on grease and hydraulic hoses in North America. We use this fitting on our quick-connect hose adaptor. It’s also perfect for building your own grease fitting relocation hoses. Simply replace a troublesome Zerk fitting with a length of grease hose and attach this to the other end and you now have an easy-to-reach remote access point. Because the LockNLube®Grease Coupler won’t leak or pop off of Zerk fittings, it works as well on this fitting as it does on any other.
