I needed a difficult to find coupling that this little kit had. At $20, it seems expensive. That being said, it did have the M6-1.0 to M10-1.5 coupling and I was able to continue on my with my project. Good price for a small piece of metal? No. But excellent product that simply works.And, I was able to get the product the next day as opposed to waiting. So, even though I think it was expensive, it was obviously worth it to me.

I got these needing most of the sizing it came with for a fair price. They all worked exactly as I needed them to, and the threading was good. Everything fit and held tight, so will buy again if I find the need.

This product is great for those high torque water tight applications where the product must be tight. Can be used in many different types of applications. Thinking of using JB weld, Dont, use this instead.
