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.

Love it

This makes quicker work of the regular lubrication needed on my tractor and attachments. Glad to see that there is a slim extension version for a couple of the grease fittings recessed in framework. Well done!

Works perfectly!

Works great. However, if you have a Lube Shuttle Grease Gun you will need this adapter: Pipe Fitting 1/8“ NPT Male to Metric M10 M10X1 Female Connector Adapter

The coupling worked very well on its first few uses. Only the test of time will tell if it is an excellent product or so so. The quality that I saw in this product tells me that I didnt waste my money. It is nice to lock it on the fitting and not have to hold the end of the hose. This makes greasing my equipment easier, and a lot cleaner.

extremely useful and it works , I wonder if they also make a right angle one?

They work very well

would not fit my grease fittings on my mower

LockNLube works great. Locks onto the fitting and stays there until you release it. No hint of a leak. Delivery was on schedule. Im very happy with this purchase.

Works real good
