THINKWORK Grease Gun Coupler, 0.53" Grease Gun Tips, Strong Lock on Greases Gun Couplers, 12000 PSI Quick Release Grease Coupler, Compatible with All Grease Guns 1/8" NPT Grease Gun Fitting

With this fitting attached to my manual grease guns, greasing cars, tractors or indeed any machinery fitted with the usual grease nipples becomes a far simpler task. The fitting “locks” onto the nipple by first pressing the obvious thumb lever and it will remain locked during greasing until such time as it is released by pressing the lever. No pressure is required to hold the grease gun in the correct position during trying to get grease through the nipple.When “locked on” the grease is reliably forced through the nipple into the bearing until the fitting is released.

Perfect for quick connections on the tractors👍😎

Great for a week then the jaws gave up and wouldn’t hold onto nipple.

Delivered quickly works well

Really good, BUT , it will pop off under quite a lot of pressure, bit of a shame but for general use really handy bit of kitUPDATEAfter a bit of use , doesn’t grip onto grease nipples, started off ok, then went downhill quite quickly, gone back to using a normal coupling

Works a few times then keeps popping off cleaned etc still no good wastes more grease and very frustrating

Waste of money. Annoyingly purchased two at the same time. They lasted about 1 day each. Now won’t grip any nipples and the lever falls off.

Absolutely terrible broke immediately as soon as I tried it
