Feedback from Quilt Lady's husband: I needed a new set of valve stem extensions because I 1 found of these The old ones are leaking on my RV They were 1" too long but no big deal Installation went fine but the schrader valve on one of the extensions was leaking. Tried loosening and tightening, still leaking. Tried that Valve from a new valve stem that was on my fingertips was leaking anyways so I've installed 1 now and the 2nd is leaking Not at all happy I'm trying to get my camper ready for the trip and now I don't know if I get a replacement Another thing, I found the spring clips to be a joke, they don't hold the extension at all so you can juggle with two hands to get the Check or fill inner tires. I ended up making a clip out of 1 x 1/8 inch. Billet aluminum, secured one end per ha ykoy and shaped/bent so the wheel cover would fit over it.
