These guys will have real Bendix parts. https://www.anythingtruck.com/category/htp-brake-air-dryerparts-ad9.html
That looks like exactly what I need. Thanks.They also sell check valve kits - I'll also get one of them, because my dryer has not sounded right for a few years when purging. Instead of a short blast of air it now vents out a longer PSSSSTTTTT of air, so I guess that either the dryer's check valve or the wet tank's check valve is not sealing well. I replaced the D-2 governor and replaced the O-rings in the purge valve itself, but it still makes the same long purge. It's probably no big deal, but I don't want to be stranded one day if it goes tits up on me.John
That maybe not all bad John the longer and stronger the purge ,the cleaner and longer lasting is the desiccant.We have 2 new MCI's here that have the CR/Holset dryers the drivers have a hard time understanding the purge volume on those is 460 cubic/inches instead of 260 cubic/inches for the Bendix AD-9 they think something is wrong with the dryer,so I have to explain it to every different driver it is the way the Holset works
