“Works extremely well,for sure the best one I ever tried. Would be nice if there where parts available to rebuild it. Unfortunately there is no Macnaught Canada, so it's a bit of a hassle to get it .”
“After reviewing several grease couplings I settled on e Macnaught unit. Placed an order online and was promptly replied to with an "ordered received" email. Ordered was promptly shipped and arrived within days. Installed the adapter on my grease gun and went to work. This coupling works better than advertised. I was able to clear and pump in grease on my toughest backhoe fittings. Easy on and off the zerks no matter how much pressure I used to pump in grease. Thanks for such a great product!”
