I am looking for plugs for my hp 100s that I am splitting. Valves are old school Sherwoods. The only plug I have is for another valve. Does anyone have a set or know where I can purhase them? I appologize for late responces, I am not on here much anymore...

I do not believe that manifold can be plugged
tbone is correct. That manifold cannot be plugged. The plug, in your hand in the picture, is the plug that fits into the Dive rite/Sea Elite/Scubapro and so on. You can buy the 7/8UNF valves at one of the big mail order companies ( sorry, forgot which one ) and that will solve your problem. A valve costs more than a plug, but in your case, you don't have any options, unfortunately!!Quote:

Well that sucks about the not being able to be plugged at all. I'll have to order some new valves. Dive gear Express does not carry 7/8 thread size. I'll have to try and look somewhere else. Thanks for all your help!
Found em! Divers supply! XS scuba valves 7/8 x14 UNF 79.95Quote:

Not sure if you can see the image or not without being on my FB friends list but if you PM me I will get you the image
What's your alternative? Have some modify a 3/4" valve to fit?

Very clever :-)Quote:

Looks interesting. What did you make it out of?
I am not sure I know how to capture a photo from FB, but I will try.Quote:

One other thing that could be done is cut the threaded part off the stock pieces, and tap the back, and put a screw in to plug them.
I see you got it already.
Good questions. I'm interested in knowing as well.
They are made of some stainless stock not sure of the alloy, I don't have any extras, and I didn't want to modify the stock valves or nuts in case I wanted to double them back up or if for some crazy reason these valves became more valuable than gold! I'm sure there are more ways to skin that cat but this is my solution. I'd still be interested in taking a set of those tanks off of someones hands if they were just you know.... taking up space.
That is a cool idea! Getting access to a lathe again may be a bit hard... has to be cheaper than two valves + shipping...
Not to hijack the thread but if you are looking for extra parts for such a project I have two sherwood dual DIN manifold center sections that I could be convinced to part with. They both consist of the center isolator body, left and right nipples and outer nuts. No internals, just the bodies. One has a little surface corrosion that doesn't show in the picture and the other is really clean.

Stop by your local machine shop with a case of beer or a dozen donuts and your parts in hand, You might be surprised!Quote:

How do these seal? Is there an o-ring somewhere?
There is a little bitty o-ring on the end. If you look at my plugs you can see the groove that it sits in.

If someone wants to manufacture them and accept the liability that's be fine by me. If someone wants to make some for their own use, that's on them. Either way you're on your own. I do not in any way endorse untrained, unqualified, or unscrupulous machinists, divers, or hobbyists copying my ideas. That said I do not have a patent on these soooo....
But if you want to name them after me I'm fine with that as long as I am not held liable for someone else's actions.
Someone asked me how these seal.

There is a small groove in the end of the nipple. It is kind of hard to make out in the picture above. An o-ring sits in the groove and is compressed against the dome shaped surface of the mating part. If I recall it is a 010 size o-ring that is harder than typical o-rings for this application.
I'll try and post some measurements this week.
