Air Brake Valves for Trucks and Trailers is a distributor of name-brand air brake parts. This includes air brake valves made by Bendix, Sealco, and Midland/Haldex, and we've made these valves available to the public at discounted prices. We also offer many aftermarket replacement valves from companies like Velvac and Pro Trucking Products for customers that want an even better price.

Best of all, there are no core charges! That's right, you can scrap that old valve and not worry about lost money. Let's say you want to install a genuine Bendix air brake valve, but the vehicle has a Midland valve on it. No problem. Install one of our valves, and you can forget all the hassles of competitor interchanges and damaged cores.

Air Valve Part Number References

There is no application guide that tells us what air brake valves the manufacturer used on your truck or trailer. The only people who can tell you what valve the vehicle manufacturer used based on a VIN are the vehicle dealers. With that said, there are other ways to determine which valve you need. You may find a label or a metal tag on the valve that has the OEM part number printed on it. Sometimes, the number is stamped right on the valve body. Raised casting numbers are usually no help at all. You're looking for stamped numbers here.

If you can't find any numbers, you can look for a match based on the pictures we provide here on This is easiest if you know at least what type of valve you're working with. Is it a relay valve or push-pull valve? If you have no idea what kind of brake valve you're replacing, you will probably benefit from looking over the Bendix Air Brake Handbook.

We try to provide a comprehensive cross reference lists for each air brake valve we offer here, but there are always OE numbers we haven't learned about yet. The list of pages below contains useful part number references from OE valve manufacturers. You can try your part number at the sites listed or just give us a call or drop us an email for help.
