Review: Works very well - Press the thumb lever to attach and push it to release. I wish that I would have had one of these years ago
Review: Exactly as I had hoped it would be - I bought this for my Milwaukee grease gun for a very specific application and for that application it IS everything I hoped it would actually be. Refilling grease fittings after replacing tracks on Case track loaders out in the field, which trust me is never any fun or easy but I found that after I finally got it on refilling was a real pain because the original milwaukee fitting would not stay on the grease fitting without me holding it very firmly and it takes awhile to do. This Saker fitting is frankly built like a tank and there is zero need to hold it at all just put it on an fill it! The only complaint is that the Saker fitting does not fit into all grease fittings, just to big but for me I don't care about that. I wanted it for one purpose and it fills that need completely!

## Questions & Answers

**Q: Where is this Grease Gun Coupler made?**
A: Quickest way to tell if an items made in China or Mexico is no COO listed. 
 Dead giveaway imo. 
 I just assume the worst when a seller/maker fails to list the COO. 
 Because for decades corps have not only known their customers want higher quality USA, Japan or German made products but they also know we don't want China-Mexico crappyola.
  Meaning? 
  By listing a better COO its the best/cheapest advertisement there is today. 
 They get asked where their products made every day so they'd proudly display a good COO & hide the bad ones where possible. 
 Amazon should force each listing to fill in COO but thats helping buyers which they no longer do.

**Q: What exactly does this do that others dont?**
A: What it does it lock on to the zerk/grease fitting. You don't need to hold it on. No more mess anywhere. It's really worth the money. When you work on cars & those grease fitting are in weird areas (tie rod end between tire & strut) you can use 1 hand & not make a mess. 1 hand on grease gun to hold it & the other hand to pump it in. Great concept.

**Q: Will valve release from a pressure locked zerk?**
A: It is a mechanical lock to the grease zerk. Mechanically it can released with the lever. Regular grease couplers are spring loaded and release by pulling and release by over coming pressure of the grease, if any. So far they have released, sometimes with a little extra thumb pressure. Good question.

**Q: Does this 2nd gen version have a smaller barrel diameter (5/8") to fit tighter recessed fittings? Or is it still 3/4" dia.?**
A: The main barrel is larger than 5/8", probably closer to 11/16", but less than 3/4". Where it attaches (screws) to the hose is larger than 3/4".

### ⭐⭐⭐⭐ Very good, but could use some improvement.
*by Z***E on February 3, 2024*

I purchased this Gen 2 version of the Saker grease gun coupler for its slender design to get into tight spots. I also bought the more expensive, but highly trusted competitor that comes with a rebuild kit. The following are my observations. I wanted a tip that I could put on and remove from zerk fittings without having to apply any force. This would be handy in awkward situations. The jaws of the competitor are freely moving and extend from the housing 1/2 inch when the lever is depressed. This allows the jaws to grab onto the fitting and tightens up as you release the lever. There is absolutely no resistance during this process. In contrast, the Saker jaws are not independent, free moving jaws. From my experience, the jaws appear to be a solid structure with slits cut into it, giving the appearance of 6 individual jaws. This gives the tip some flexibility when pushing it onto the zerk fitting. The jaws only extend 1/8 inch from the housing when the lever is depressed, thus limiting the jaws from expanding. As a result, it requires a small amount of force until it snaps into place when applying and removing the coupler. It’s not the end of the world, but in a tight, awkward space, it could be inconvenient. As seen in the photos, the Saker tip is longer, which comes in handy with recessed or shrouded zerks. The overall diameter of the Saker Gen 2 is 14 mm versus 16 mm with the competitor. Overall, I think the Saker is a fantastic product for the price point. I personally wouldn’t even consider any of the other cheaper options. I prefer the more expensive model over the Saker because there’s absolutely no resistance when applying or removing the coupler, it comes with a rebuild kit and its long-standing reputation. You will need to decide for yourself which will fit your needs best. For around $20, the Saker is very respectable! I hope some of this detailed information helps!
