Looks solid: Lock and lube grease zerk coupling
Well made grease gun coupling. Looks like a solid addition to the grease guns if you don’t have one already!
If you have ever greased a piece of equipment with a worn out zerk tip, this one probably already has your attention. This zerk end looks like a must have if you’re maintaining the equipment you’re running! The tip locks to the zerk helping to prevent grease blowing past it and making a mess! Very cool.
