Air Drain Valves

That's a slightly different part but might be the same with the exception of the end adapters which can probably be used on the one in the link. Thanks for that I went ahead and ordered one it was $91.12 after ship and tax. Oddly I did search for that part on the US Haldex website and came up with nothing.

The stock part number is N30261B and a search for that gets you MME at $220, Memphis at $210 and fleabay at $250. That's where those numbers come from.

It is the same part exactly. It requires no modifications. I've installed them as well as just using the diaphragm out of them. I'm assuming the part number difference is materials, coatings, components suppliers, etc. Or it might just be that the government version has a different part number for supply chain reasons or because uncle sugar wants different packaging or labeling. Or indeed a different set-point pressure or tighter tolerance for the preset..... or it might just be green paint. Probably the paint color.

And the price point is just surplus scalpers. The military pays $84 for those.

The rule in this world is to NEVER buy from surplus vendors unless you have exhausted all other possibilities or it's a really good deal because no one knows about it.

I have only seen it listed overseas. It is a metric port valve with the adapters on each end to provide a US standard.

It uses the disc also as the sealing material, unless it has been beaten to death with a hammer and the case is cracked, if it is leaking, the disk rubber has deteriorated which is why it is leaking and sealant will most likley not help you… it is just a simple rubber disc. Cut out a new one from comparable thickness rubber gasket material…

Have considered that also. Just too busy and don't need that many.
