Best grease coupler?

[Hardline]

Okay I see a ton of threads about best guns and best geese but what about the couplers? I have tried lincolns, zee line and others. Best so far has been zee line but only got a week out of the last two I bought. I hate when the spew grease more on the outside of the fitting then they are putting inside.

Alemite makes their own, they are made in the USA and they are top notch quality. Zeeline is china crap, Lincoln out sources theirs.

all others are too big to reach uni-joint nipples, they all wear out as do nipples (they don't last much past 20years )
