I have a D400 ScubaPro Second stage and I cant find the O´ring pointed on the photo below. I hope someone could help find it or the complet kit to leave my reg working again.

Figure out the size and you can get the replacement o-ring online for super cheap

I only have the part number (01-050-323) and not the size. I will try to get that info. Thanks

Im not sure about finding it super cheap online. IIRC its a metric 4x1mm and no supplier was selling them (except custom order). I would want to be mistaken though.
The kits were available on ebay

Please see an authorized Dealer for parts and service on your D400.

Take the old o ring down to a hose shop and most likely they will have one. ALL o-rings have a + and- difference , And that's from the Parker handbook for fitting O-rings. the black rings are standard buna n material. I've been rebuilding Conshelf Regulators for over 40 years with some store bought O-rings so far never had one problem...

I was not aware of that from manufacturers other than parker I always thought parker was the standard. However buna n works fine in any of the conshelf regs I have ever rebuilt. I dont see why they wouldn't work in any regulator. I know take it to the shop.

Thank you all for your coments and advise.

I never buy the Aeris battery kit for my dive computer. $10 for a CR2450 and an O-Ring? Please. Buy the CR2450s 10 at a time online and you they're around $1 each. O-Ring = a few cents (bulk purchase, but some of us really need lots of types of o-rings for service).
