Dsycar 45 Degree 90 Degree 135 Degree Brass Valve Stem Extension - Set of 6 (Silver)

Works as expected

I put new wheels and rims on my RZR side by side the wheels and tires were great but I couldn't put a tire gauge on the valve stem. I use the 90 degree extenders and they worked great.

A+

Seem to be well made, but found that they work with some valve stems, and don't work with others. They attached to my car valve stems and worked fine, but when I put them on my RV valve stems (which is what I bought them for), the pin didn't make contact with the pin on the valve stem, and didn't allow air to pass through, so they were useless in that application.

As the title suggests, adding the adapters made it easier to inflate my R100RT snowflake wheels, but I don't think it's giving me a tight seal. Since adding them, I seem to have a slow leak in the rear wheel. That being said, at least I can air up at any gas station now.

Needed these for access to the inside dually valve stems. But, there was no way I could see to put them on while the tires were mounted. They'd be fine, if the wheels/tires were not on the vehicle. Bummer, because they were a great price, and were sorely needed.

Bought these to add air to my dually tires, motorcycle, dirt bikes, etc.Easy to use and to get to the hard to reach places.I don't leave them on, i just use them to add air.I read they can leak if you leave them on. I imagine they would, with the wheels spinning and all.

Hard to keep them from leaking, also the 90 degree ones, loosen up while you go down the road. But they're better than nothing.
