Today we're going to review part number AM20904. This is a high pressure rubber snap-in valve stem. it has a maximum inflation pressure of 80 psi and it has an effective length of 1 1/2" long. These tubeless snap-in valves for high pressure applications are designed for medium and heavy duty trucks and trailers. These valves must be used when a recommended cold inflation pressure on the tire exceeds 65 psi. These high pressure snap-in valve stems for wheels with the .453 rim hole, which is what this valve stem would fit in to, allows a maximum cold inflation pressure of 80 psi. These are typically used in steel wheels.
High pressure snap-in valve stems will combine a thicker rubber snap-in base right here with the metal barrel and has the plastic cap. Again I mentioned the effective length on this is 1 1/2" and that's actually measured once it's installed in the wheel so the effective length is actually going to be measured from where it comes through the wheel to the top of the cap. If we put a ruler on this, it'd be a good idea, you can see the inch and a half effective length. That should do it for the review of part number AM20904, the high pressure rubber snap-in valve stem with the maximum 100 psi inflation and the 1 1/2" effective length. .
