To be honest I bought this kit to get the right color parts. Everything this kit has replaced on my ender3 pro has worked fine. but at $20 all the anodized metal parts seem like a bargain! Another reviewer said there is no thread, he's right but also wrong. You use a small black element with 3 tabs to slide in there. Insert the tube and then insert the blue gasket. I was confused too but then I opened the product page to see if there were any instructions. It says so in the product photo.
