RAYMOND INNOVATIONS 4-Way Tire Inflator Chuck for Car Air Compressor Inflates, Deflates, Balances Air Pressure in 4 Tires at Once, Open flow - cars, trucks, ATVs – Compatible with All Tire Compressors

This system works great besides for one small flaw that air leaks out of the checks when all are not connected. I couldn’t imagine it loosing more than 1PSI max before I can get them all disconnected. I’ve only used it once but it seems to be good quality.

DO NOT BUY. It's a tangled mess, but I took the time to set it up. They leak, there is no way you can wiggle all of them at one time to make sure they seal. I was so frustrated I took more joy in throwing it in the garbage then getting my money back.

I had to swap the connectors because there's no valves in them so as soon as you disconnect 1 tire air from the other 3 comes out rapidly, so unless you have 4 people to disconnect them all at once it wont help, and even then it wouldn't be very convenient, takes a while to setup and take down even after swapping the connectors. I can just run around the vehicle and hit every tire real quick with 1 trip around faster than this. But great concept, poor implementation. I don't regret the purchase.

I can't use it because my portable compressor puts out too much psi. That said, I bought it just to see if it might work anyway.It's a light weight build so I'm not going to risk it. It's also a bit too tight of a stretch on my Wrangler Unlimited and pulls the valve stems much harder than is safe for repeat use.I don't see a use for it in any other situation, but it gave me an idea for making my own permanently placed 4-way line to run to my new 15 gal. CO2 tank.

It functions, kinda. The system is open, so everything starts deflating as soon as you hook one tire up. Sometimes the tubes come out of a joint and you lose a bunch of air. After trying a few different times, the best approach I found was to place it loosely on all four tires, have one person kink the air line, and rapidly attach them. An even better approach would have been to not buy this cheap crap and get something nicer. Life and learn.

I use it for airing up and down. Works great. Does get pretty hot during use.

I wanted to like this! It’s not as bulky as other kits. But I suspect that’s maybe why it doesn’t work as well? (Small diameter?)I even tried different ends that attach to tire valves with same result. I would get higher psi in tire closes to point of air input. And less at tire far away. By as much as 7 psi. Going in trash. 🙁

Great addition to my arb twin compressor on my Jeep. Only flaw is that it uses open chucks instead of closed so when to disconnect one tire air leaks out of the other ones as you disconnect them. If you leave the compressor running while unhooking them it is ok but this really should have closed air fittings.
