Slime 20332 Inflator Hose Adapter - Universal Air Compressor Accessory for Tires, Balls & Inflatables | Perfect for Car, Bike, Sports Equipment & Pool Toys Inflation

I thought my new electric inflator would be easy to use on all valves with its screw-in connector that would always maintain a tight seal. I immediately ran into problems. The screw-in barrel is solid brass but it is narrow and hard to grip and there are only a few threads available to tighten and even then you have to pull back core to get access to those threads. The result is that it's easy to cross the threads and on some of my valves, the threads were damaged and it wasn't possible to use the inflator at all. I was going to return the inflator for a similar one with plastic knurls on the barrel but one of the reviewers also noted problems with the screw-on connector. There's also the issue of losing a fair amount of air when unscrewing the connector.This device removes that problem altogether. It's nice and short and seems to work on all my valves apart from one that I had to do a special repair on. For that one I can only use a push-on gas station type filler.
