This adapter is a game
"This adapter is a game changer for putting air in trailer tires. I tried it with my 14' tandem axle trailer, plugging in the adapter into my tow vehicle (Jeep Grand Cherokee) and using my Vivair 88p SxS air pump to topoff the trailer tires. Worked perfectly. Having the air compressor plugged into the rear of the vehicle gets it alot closer to the tires on the trailer and tow vehicle, too. Very well made adapter and connectors!"
