TR-416-S 1" Outer Mount Metal Valve Stem (4 Pack)

I was apprehensive about installing this on a curved part of the pump sprayer. Fortunately, it turned out great. Now instead of hand pumping, an air compressor (30psi or less) pressurizes the tank. A few tips for installing on a poly tank: 1. When planning the valve location, be sure the position of the valve will not obstruct the tank's lid removal. 2. Be sure you have pliers that will be able to secure the valve from the inside of the tank while tightening the lock nut. Channel locks in my case worked. 3. Use a drill bit slightly smaller than the valve stem and attempt to "cut" the threads into the poly (you can always make the hole larger if necessary). 4. Although not necessary, use silicone on both sides of the valve before installing if you have some on hand. 5. Don't attempt to install this in place of the safety relief valve. The relief valve plays an important safety role of tripping in the event of an over-pressurized event. On my pump sprayer, it is designed to trip between 36-40psi. 6. On most spray tank's, 30psi or less is likely a safe pressure and should be tested before use. Your safety relief valve should activate if your pressure is too great. Regardless, it's better not to approach that limit to remain on the safe side.

I was pulling my travel trailer home a couple of weeks ago from a 10 day trip. About halfway home, my TPMS indicated that I had flat. I got out to check and sure enough I had a tire going down. Unfortunately, the cause of the flat was the TPMS itself. The weight of the sensor on the on the end of the valve stem caused the valve stem to split at the rim and lose air. I still like the TPMS system so I ordered these metal valve stems in order to not to have to worry about them breaking from flex while using the TPMS. They went on easy and I had no leaks around any of them. I like them so well I ordered another package so I could do my spare also. I have read some reviewers having issues installing these on rims that have a recess for the valve stem. Fortunately, I did not have that issue with mine. One issue I did have was trying to break the bead on the tire so I could install the new valve steam. I found a video on YouTube showing how to use a floor jack and a ratchet strap to break the bead, which ended up working pretty well.

seem to be a good product at a fair price

Bought a four pack got a three pack but luckily for me I bought them for a supermoto dirt bike so I only need two but great quality and for the price I can't complain that much it looks like I am the only one who has gotten only three but it seems good and 'm ok with it still better than a rubber one

work perfect

Easy to install. Look good.

Bueno

Prefect part

Nice valve stems, good quality!

I live in Darwin, and was told by tyre shop that some of these rubbers can’t handle the tropics. So I chose not to install them and went with conventional proven valve stems. Had bought these for installing blue tooth remote tyre pressure guages

Nice looking valve stems for chrome or polished wheels

Perfect replacement for same ones on my wheels

This Valve Stem Type Cant Be Used for Recessed (Sunken) Valve Stem Holes, ( as you cannot tighten their provided 9/16" (14mm) top security nut , if the top security nut was 1/2" (13mm) then No Issue,,This Valve Stem Type Can Only Be Used On UNRECESSED (Flat Surface) Valve Stem Holes
