Great Coupler for Tight Spaces!
The outer diameter of this coupler is smaller than the thumb-actuated coupler so it can fit into tight spaces such as the middle Zerk on driveshafts U-joints. First loosen the endcap on this coupler to open up the jaws, then place the open jaws over the Zerk and tighten the cap to close the jaws. Then attach the thumb-actuated LockNLube coupler to the built-on Zerk on this 90 degree coupler and start pumping grease. Easy and no mess!

Nice addition
This attachment was a must need. Love the way you can loosen it to get off zerk. Still need to apply a bit of pressure to keep grease going in, overall live it.

In some cases it’s handy
Didn’t want to have to use this coupler fitting but I needed it to get to one grease fitting so it got me out of a jam. It’s kinda handy.
