PROLUBE Quick Connect Metric Grease Fitting Adaptor, 90 Degree Angle, 4.9 mm Diameter Greasing End, Max Pressure 1,000 PSI, for Use with Hand Operated Grease Guns (44922)

I used it to grease the landing gear on my camper.

Bought this item to get into tight spaces, however it won’t fit on the grease fittings! Useless tool !

Finally got a chance to use it, only to find out the the end will not fit standard zerk fittings.

I bought this to grease a very difficult to get to zerk fitting. In concept, it was what I needed. The only problem is, the fitting on the end does not fit over a zerk fitting, so basically, it's useless. I'm not going to waste my time or money trying to return it, so I'm just leaving this review so someone who's trying to grease an automotive zerk fitting with it isn't mislead as to its capability.

Does Not work for tight confined space knuckle joints on a 4x4!!! Returned!

Useless for me - does not fit any zerk fitting - output maybe 2mm bead - leaks at connecter

Will not lock onto a standard grease zero fitting. Totally useless!

This did not come with a grease fitting. I had to purchase one but it made the device almost too long. Made connecting it to the zerk fitting difficult.
