durable stirdy item
The coupling is made of a very high quality stainless steel, you cannot bend it by hand, it is build to last. It contains a ridge that separates the two liners. Since this is a very simple piece, not much to write about, I will also tell that since the original liner I have purchased from another company and the liner to couple it with arrived from Woodland, they have slightly different internal diameter. The other liner would not go onto this coupling. I am yet to remeasure which part's fault is it, but this is more like a comment, rather than a con. Thank you to Woodland for getting me this one, it was very sweet of you to understand and help me with this issue of mine!
