Delta/Alpha Dowty Washer

Don't know if you have issues purchasing through AliExpress or not but here is a link to various vendors with many sizes and kits to choose from: https://www.aliexpress.us/w/wholesa...usy%25252dCorner.html?spm=a2g0o.home.search.0 . I purchased a kit of various sizes some time back and have used them on my Enduro motorcycle as wall as my FX Impact MK2. Hope this helps.

When mine went bad I pulled one out of this kit from Amazon.

Self-Centered Bonded Seal Oil Washers Gasket Assortment Kit with Box(150pcs,10 Sizes/M6-M24),for Automotive,Bearings,Pumps and Many More, by LIYYOO https://a.co/d/iou9Klj

It lasted actually a long time I think over a year before I replaced it with another in the same kit.

I always want to get the fx one but it was not until a couple months ago I got some from huma-air when I bought a bunch of other stuff.


And you probably already know that the bottle valve is the same thread diameter as fx but different thread pitch.

Other than that no actual bulk dowty seals that I have found yet.

These are 19mm od vs the 18mm od of the factory Dowty Washer. They sealed the gun up just fine.

that's interesting, when I dropped by and got the spare bottle fitting from utah air, fxUSA was doing the transition and had all their stuff there. This washer was on the fitting.



And the measurement is 19mm. How much were the washers?

And next to the huma washers

I just looked on line and M12 X M18 are .73 ea for 25 pc order and M12 X M19 are 1.64 ea for a 25 pc order. They was out of M18 when I ordered last.

That is alot better price. Keep me updated if they work ok. I will have to go that route.

Thanks

More importantly, do they work in this application? Are they sealing ? No weird leaks?
