My compressor plus tire inflator previously occurred. As far as I can not say anything about the here often criticized compatibility issue. For me, the fit immediately into the mouthpiece of the tire filler. It even fits exceptionally well and stops reliably; better than many a tire valve. A bit of force is necessary, however. Even a little force is required for pressing the caliber extensions as they are for example used for air mattresses, swimming pools and inflatable boats, to the common carrier. Even after it clicks the connection is not completely airtight. That may be a shortage, but I'm not really angry drum. All these things only tolerate very low pressures, and they crowded quickly when one has only to inaccurate gauge of a tire filler as a guide. The leak is in mini-compressors a safety function, people with large compressors must give himself to watch. Otherwise, I think the compilation of the set very useful. My inflatable things are so in any case covered and I am very happy with the product.
