LockNLube Grease Gun Coupler locks onto Zerk fittings. Grease goes in, not on the machine. Worlds best-selling original locking grease coupler. Rated 10,000 PSI. Long-lasting rebuildable tool.

Excellent product; easy to use and install. The grease goes where it is supposed to. Thanks

Never loose a drop of grease. Probably pays for itself after just a few uses.

I own a Skidster I rent out and have about 9 grease points to do every couple of weeks. I could never get the tip off and it drove me crazy. This is amazing, made it so simple to grease. Wish I would have found this a couple years ago. Works perfectly.

This part is the best. I struggled with the price but once I used it, I ordered 2 more. Best money ever spent!

Arrived on time & as expected - thanks

I work on outdoor power equipment as my profession. I also use my grease gun every single day that I am working. I am very satisfied with my purchase of the Locknlube coupler. I have eliminated excess grease around the zerk fitting. If it is locked on, grease only travels thru the zerk. I wish I had known about this product 30 years ago. FYI: the Locknlube coupler is a robust adapter, you may encounter some difficulty attaching it in tight areas. Definitely worth the investment.

Works great

After 2 of my favorite YouTubers highly recommended LockNLube, I had to try it. Just installed it on my Milwaukee cordless grease gun, Im a believer. Thanks to Outdoors with the Morgans and Wranglerstar for recommending this product.

Works perfect - no more issues

Very good product. Have turned several of my friends on to this item. I have one on each of my 4 grease guns.
