PROLUBEQuick 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.

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.

Just what I needed!!

Product is good quality, tried to use in tight fit compact tractor universal joint but wouldnt seal the zirt fitting. Good fitting to have around for other uses.

works as it should. Solid and well built. Compare it to the snap on one.

Very good purchase! Helps as never. Easy to apply and proved my expectations for 100%

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

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