CKAuto 4 Pieces TR416 Metal Valve Stems Outer Mount Fits .453" & .625" Rim Holes Long 1 1/2", Silver

I installed one of these in my 110 psi RV trailer tire today, and it is fantastic! I did notice that the valve stem core needed a slight tightening though. Well built product, thanks!

I purchased these for a heavy duty machinery laden trailer, holds a backhoe or a vertical lift, so tires get abuse.... I have removed two wheels in order to sandblast and paint, and decided that these valve stems would be ideal.... However I am not a keen proponent of metal on metal, so I am planning on using the smaller rubber washer on the inside (which is the right fit for the hole) and on the outside substituting the larger (and in my case, extra) washer down onto the rim so rubber is against the metal rim, and then securing with the nut. The metal washer that was supplied will not be used as it cannot go on top of the larger washer because then the nut has no thread to grab.... The photo shows the outside with the larger rubber washer and nut, while at the top it shows the inside of the rim with the smaller rubber washer, and the two “not used” metal washers are sitting on the rim to the left. (Excuse the rust on the rim, as that is why I removed the tires to address and paint) I am wondering if anyone else has done this alteration, and also if the manufacturer has any comment as to it being installed this way.... I also intend to take a small dab of Slime and apply it to the bottom of each rubber washer so there is that barrier between the rubber washer and the metal rim. This should inhibit any corrosion as well as seal it. As I am just starting the sandblasting/painting of these wheels, I have time before these will be permanently installed. Any comments and suggestions are welcome, so long as they are civil in nature! UPDATED: I have added a photo that shows my final decision on the valve stem installation.... I was able to compress the two washers enough, one on each side of the wheel hole, that I could still use the metal washer and get the nut on.... it is very nice and tight.

The stems arrived on time and in good condition. I am impressed on how well the workmanship is on these stems. Well worth the money. No problems.

Really good quality, doesnt leak

Almost a really good product. Rubber won't deform to curves on rims so I had to return it. Needs a cone shaped rubber washer for both sides. Really nice all metal stems. But unless you have nice flat faces for your stems, good luck getting it to seal unless you have a really flat sealing face.
