I have two small compressors for inflating motorcycle tires. One was fitted with this type of stop-chuck and the other had (was) a stop-chuck that used a collapsible stop-lever. This folding style flowed like crazy when I was trying to install or remove it, and I had to use both hands to attach the Schrader valve - squeeze the chuck with one hand and fold the lever with the other. This product has allowed me to change that style of lever and it is now as easy and convenient to use as any other compressor hose. No leaks, one-handed installation and removal. I'm also planning to convert the tube from an expensive Longacre tire inflator that I use in conjunction with a tire changer so I have one hand free to position the tire bead on the rim while inflating. Instead of using a worm-driven hose. Clamp included (2 cartridges per pack with 1 hose clamp?), I recommend using an Oetiker clamp as shown in the picture - your hands will thank you.
