This high pressure rubber valve stem is snap in and 1-1/2" long and fits through 0.453" diameter rim holes on trailer wheels.

Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
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. .

Great price and fast shipping I will do business with etrailer again
This is a nice valve stem recommended by etrailer but, did not fit the wheel I ordered.
looks heavy duty, great quality for the price .fit great and quick shipping, Thanks !
Have good experiences with website/research/ordering process, fast shipping, communication, and good product. Will definitely do business again!
Not much most people can say about a valve stem. Its seals well, installs easily, never had a problem using these on either of my trailers.
Beautiful wheels and nice tires, shipped quickly at a good price.
Simple product but these valve stems look to be of high quality. They work well for Load Range D tires.
They seem to have popped right into the steel trailer wheels I bought, and appears to be holding air. Only time will tell!
Quick shipping and product as described. Make sure to check that you have the correct PSI valve stem when you buy trailer tires.
Have your trailer tires balanced it makes a difference.
Customer service was excellent. Ordered the wheel over the July 4th holiday and received it in 3 days. Shipping was upgraded from 5 day to 3 day delivery with no cost to me. Wheel fit perfectly and now I am good to go with a spare tire for my trailer.
Use these in my Ranger boat trailer tires, which are set at 50psi. Solidly made and I keep a few spares just in case, but have never had to replace a stem that I have purchase from etrailer.
Simply great product.
These valve stems to appear to be high quality looking. They fit perfectly, and are rated to 80psi. One did not make it in the shipment. The peps at E-trailer immediately sent another one. The ups to usps was not that good; it took over 5 business day to get it.
Have held up well with over 7000 miles on wheels. Tire Minder TPMS installed on these perfectly and worked well.
The wheels arrived double boxed with internal rim protectors and were in perfect condition. The finish and detail are excellent with no blemishes on the outer surfaces that you see once the rim is mounted. Shipping was fast and ordering very easy. I had some questions on the product and Patrick O. helped me with them. Patrick and etrailer made this process very easy. This is my second purchase from etrailer and I am very satisfied with both experiences. Thanks.
eTrailer does what they say they will do. good products, prices and prompt delivery. As an ASE certified mechanic I highly recommend them. Most folks do some sort of preventative maintenance on their vehicles but trailers, tow behind trailers and RV's don't usually get maintenance until something fails. I call this reactive maintenance rather than pro active preventative maintenance. Tires, wheel bearings and electrical systems are highly neglected until a failure occurs.
Thanks eTrailer and Suzanne T. for great service and a good product. Order was placed on a Friday and received shipment the following Tuesday.
My order was for Dexstar wheels AM20522, center caps 319EZ-SS, and valve stems AM20904.
The only reason I did not give an excellent rating was because of minor paint blems and knicks on the face of the wheels. Nothing major at all.
The ole trailer looks good with fresh wheels, tires, center caps, and valve stems.
First of all, I want to say that eTrailer is an awesome bunch of people to work with. They know their stuff, have great products and excellent instructional video's. I ordered new rims and complete brake assemblies and they were perfect. The shipping was extremely fast, the fit and function was exact and the brake assembly was as easy as the video made it out to be. Thank you VERY much for your help, great prices and excellent customer service. I am a customer for life! Thank you!
Bought these valve stems to go along with the wheels purchased. Paired with D range tires and inflation pressure at 65 psi, these valve stems have performed nicely and not a single problem. I would not hesitate to buy these again.
installed as expected. I only have 10 miles on the valve stem. They are staying together so far!
As always, etrailer performs top notch. Great delivery and great service.
The website is informative and easy to navigate, the prices are great, the packaging was exceptionally good, and the delivery was fast. Thank you!
Seems to be just what I was looking for.

It is still working as expected. It was a simple process to order the valve stem, take it with me to the tire shop, and have it installed when I had my tires installed.
I had to upgrade the load rating on my trailer tires which required 80lbs PSI the original stems where rated for only 65lbs so I upgraded the stems to increase tire PSI was easy to install and have worked with no problems
It was exactly the parts I was looking for
Well made and fit my Intech Flyer Explore alloy wheels perfectly.
