of customers said they would buy again & recommend Saker to others.

I had been wanting to try a locking quick-disconnect coupler for quite a while. I saw this one and was immediately hooked by the very fair price, and the strong construction. After receiving it, I tried it out and it was exactly what I needed. Once pumping pressure is exerted from the gun to the coupler, it holds tight without assistance and without leaks. It is an excellent value for the money.

I wish I knew about this before. Makes greasing a breeze. Wipe the fitting, put it on, flip the lever, and it’s locked on. No leaking when pumping. Done greasing flip the lever and it comes right off no pulling and tugging. Excellent Item!

Aaron R. Dad and Handyman from Reston, Virginia

I hate it when you put the grease gun attachment on a fitting and then it pops off, usually making a mess. When they came, I replaced the old coupler with the Saker coupler on two difficult fittings and it worked great, hung on perfectly. I have one for the boat and boat trailer gun, and one for the rest of machinery. Should have had them for years.
