Pacific Dualies 18135 135 Degree Valve Stem Extension - Set of 2, SILVER

I’ve had them for a few months and had absolutely no issues. I’ve done several long road trips with my RV and they make it so much easier to check tire pressure and adding air. Highly recommend.

Works as it should.

These looked like they were of decent quality. Unfortunately, I returned because the package was used.

Installed on Winnebago F53 chassis class A motor home with chrome wheel trim rings. Easy install, lost some pressure while tightening. Used soapy water to test for leaks and didn’t see any bubbles. Put the pressure back up to 82. So far I rate these 5 stars as the quality seems good and the fit is just right. Could be 1/2” longer but they work as is. I will update this review if there are any issues when I test the tire pressure next week.

product hasn’t leaked yet.

I put these on my class C motor home. It's built on a Ford E-450. I could never check my tire pressure because the outer tires valve stem is short and faces toward the center of the vehicle. Even the shops I took it to could not check. I can now check pressure and fill my tires as needed. They function as required. That's the best thing I can say. Installation was a b***ch. I don't have particularly large hands, but I could not get the nut in the valve stem. I had my wife get them started. Then tightening them with plyers, because the designer apparently doesn't know about hex heads. If I had a do over I'd look for ones with a hex nut and a slightly longer stem

These 135 degree valve stem extensions solved a huge problem for me and my RV. The rear axles are duallies. The inner tires already had extensions on them. However, the direction of the valve stem on the outer tire made it almost impossible to 1) check the pressure and 2) put air in the tire. I looked for a solution and hoped when I ordered these the would work. I was on the road when I ordered them and didn't get a chance to install them for about a month. When installing them, I removed the simulators (RV Hub Caps). While putting them on the valve stem, they depressed the stem and some air escaped until I finished the install using pliers. They were easy to keep aligned with the opening in the simulator. I can now check the pressure easily and if air must be added, they stay firm so the inflation tool does it's job. If you have a dually (whatever) and are having trouble with tire pressure measurement and inflation, check your hubcaps and see if the 135 degree is what you need. It works and solved my problem.

They both leaked. Yes, I have steel valve stems and they were properly installed according to instructions. I tried tightening them gradually and they kept leaking. I eventually used pliers and tightened them very tight. They leaked no matter what I did, not only at the valve stem but also at the end of the extension where you fill the tire.. The leak was very slow and I probably would not have noticed it until it was too late if I hadn't applied soapy water to them and looked for bubbles. The bubbles were a dead giveaway. If I had gone on a trip with my motorhome, I have no doubt these would have resulted in expensive tire failure. Don't buy these.
