Scubapro D400 Diaphragm Source

Ahh, figures since they aren't included in other service kits. I bought an old d400 when I first started to learn about servicing regs but haven't had the courage to pull it apart yet. Thinking about picking up one of those kits from Bryan and just jump into it. Wishing he would post a video as he has with other regulators.

They are not that complicated. Just different. I have some service literature I can get to you. Halocline, rslinger or Axxel57 are all very knowledgeable on these regs. I'm no expert but have more or less successfully serviced two and of course happy to help anyway I can.

The VDH kits do contain more than the official SP kits which only contain the poppet assembly, square switch O ring and lever nut.

Actually the photo on the vdh site linked above looks like a OEM kit. A few years back I bought a bag of 50 D series poppets and put together a few kits including all the o-rings for the D series and/or Air1 for vdh. Those were just packaged in a small baggie. They included a round o-ring for the switch.

Getting back to the diaphragm, I think I have 1 spare D series diaphragm and I can't sell it. But, I've had it for years, which means I've gone through maybe 10 D300s without ever needing to replace the diaphragm. So chances are very good that buying a D300/350/400 used would yield a good diaphragm. There is an assembly to it; exhaust valve, a little post, and cap.

You do know that as soon as you sell your one spare diaphragm you'll need it right?

Edit: I just looked thru my stash-sorry no scrotum diaphragm in there. I did see some odd looking items that might be the exhaust valve. I cannot tell from the diagram, so if someone can post a picture I can confirm.

Thanks for the clarification Matt, I haven't actually seen the kits on VDH I just remembered you making some for them that included additional O rings so assumed that's what they were selling. My mistake.

Yeah, I've got extra D-series diaphragms. PM me, and we can take care of it.

I started a conversation. Not familiar with Napa Scuba at the Gmail place. Is that a Google storefront?

I think it's part number 27 he's looking for.

That would be correct.
