Works as it should. Connect it to your truck's red catenary. Squeeze the trailer brake lever and you're ready to inflate your tires! Connections look intact, no leaks. It comes with a double-sided chuck so you can inflate the inner and outer hoops. When you let air flow through the hose, the hose doesn't get stiff or squirm like a snake. He stays where he is. I like it. I chose this hose over cheaper hoses and am glad I did. With this hose you pay for quality!
