Just used for the first time - MUCH better than the old pump heads. I have a Craftsman (Ryobi I think) manual tire inflator. The original tip and the one it replaced were rubber grips that didn't hold up well and would soon wear out. I bought a heavier replacement from my local auto parts store. It was very difficult to use and I had to flex the bar a bit to get it working which caused wear on the inside of the bar. LUMITECO 1/4" brass tire blower: (1) was easy to install, fits perfectly onto the compressor hose and the little clamp that came with it was better quality than the ones I bought at the auto parts store. (2) Fits the stem exactly ( 3) The yoke holds onto the stem very well (4) It's made my life easier (5) Great price (6) Seems well made, doesn't wear out much for a low price and I would buy it again if I ever got one others needed.
