Decided to grease the kingpins this morning. When away from my compressor I have a very nice grase pistol that takes cartridges. The socket at the end of the flexible tube pops on the nipples quite easily and grips well. It never pops off by itself and never leaks.

That is the problem. It goes on the nipple easily enough but doesn't want to come off. The bottom one can be prised off with a screw driver blade but when on the top nipple there is not a point to lever against and it requires a lot of tugging to get it off.

I now have two nicely skinned knuckles swear

Note to self: Next time wear the gloves you knew that you should have been wearing in the first place idea

Or a “G-coupler” as found on ebay. It really works. Holds on at any reasonable angle without grease escaping and easy to remove.

That looks interesting. I will see if it is available in Europe. Thanks for posting.

Seems to be exactly the same thing as the Alemlube unit if the photo on Amazon Italy is anything to go by. I found it searching for "quick release grease gun coupler".

More difficult with a flex hose I agree but you need to move the locked on grease head sideways until it reaches the limit of movement determined by shape of grease nipple. Further pressure sideways will allow leverage and it will/should suddenly drop off. Much easier when grease head attached to solid pipe. Trying to pull off straight will generally not work!

Or you pull up the air release valve on the grease gun to let off the pressure.
I now use this gripper & it is brilliant. well worth £7.

Thanks John, never tried that. Only ever used the air release valve after topping up with grease or when lever goes limp.

My ancient Wanner grease gun and the ex WD predecessor both had two valves on their body, one of which is used when the lever is not able to pump the grease just loaded, that valve when opened bleeds air out of the pressurising cylinder through a bleed hole which once the air is dispelled, oozes grease out of the bleed hole. The second valve bleeds the delivery tube to allow easy removal of the gun`s connector to the nipple of the object to be greased.

I suspect any grease gun should lock on to the nipple really tightly in order to deliver a rather high pressure as may be required on some items to force the grease in to areas where old grease may have hardened or other detritus has built up inhibiting the distribution of grease which requires quite a locking force on the nipple.... Forcing the gun off the nipple can wear the head of the nipple around which the gun connector grips to the extent that the ability of the gun to grip the nipple may in time be reduced...

Happy greasing...(-:

A good tip Richard. I did a bit of searching and found this. I just might try it in the morning.
