CopeBuilt Construction & RenovationCopeBuilt Construction & Renovation: These just arrived. I have not installed them yet. I thought they would be longer than the 6-in cousins advertised elsewhere on this site by other sellers. I already have extensions on the inner duallys. These would probably work fine and then application. However, I was looking for an extension to make a u-turn from the inside of the outer dually tire. I thought I was getting a lot more than 4-1/2 inched of flexible area, based on seller photos and descriptions. Deducting a star for that. I guess we'll find out whether or not this works on my setup when I try to install them next week.

I chose these because they were advertised at 7 inches and because they had a hex nut on the female side to allow for the use of a wrench when tightening.

It's times like these that I wish Amazon sellers would do a better job of photographing their items with more details when they list them... For that reason, I have attached an image of the item I received next to a ruler, to help future purchasers better understand what they're buying.

Pat Hamlin: They work well for inflating the dually's on the rear. One of them leaked after installation. One of my rear tires kept losing air. I put checked the tire with soapy water but the slow leak was coming from one of the extenders. Only one of them was leaking out of four.

Alice Budney: Easy to install. Had to replace an existing extension that was leaking on the swivel joint. So far tire is holding pressure.

Jean cholette: It was long enough to reach rim no 1 but screw to rim could be better.

Lorne Ellickson: 5 stars because the seller was quick to resolve a problem. I ordered a set of these and within 100 miles one of my inside duals kept losing air. Turned out it was the coupling on one of the extenders. The seller had a new set to me in 2 days and I haven't had any problems since.
