I'm sure some of you are familiar with the old problem replacing later, unobtainable Snark Silver poppets. Several of us have been working on this. I've modded a USD square poppet cup by cutting off the shaft, drilling and threading the hole and installing a custom post. This is a potentially great way to make the early Snarks rebuildable by using a USD style poppet puck. There are issues with this which we can address later. In order to use an early style poppet in a later regulator, you need to drill out the Silver cover so the larger early post will fit OR a new guide/cover is required. I just made a few adapter covers. This is a new custom poppet and a new custom cover: This is a photo of two new ones and the OEM Silver cover: And here is a Silver regulator with a custom old style poppet and a custom cover installed: I hooked it up and it works great!

Phil FYI I have late model Snarks with 2 different length pins on the poppets. The one I have with a HP port uses a longer one

Hey Skip, Is one a "peacock" case and the other the plain type? Also, does the one with an HP port have an integrated first stage "nozzle"? There seem to be 3 kinds of silver: the traditional "peacock"; the one with an HP port but with a removeable nozzle; and the latest one with a cast in nozzle. I have had all 3 Silvers, but never noticed that the poppet length is different. I wonder why that would be? I have no idea where I got them, but I have two poppets with 2 1/2" pins. They are identical at the head to Snark Silver poppets. Do you happen to have the measurements of the two poppets?

Phil FYI I have late model Snarks with 2 different length pins on the poppets. The one I have with a HP port uses a longer one I owed few snark, almost from the early, to the latest model. I notice that one my second generation poppet, is a little short that the others, I thought that it was due to the thickness of the mould rubber part, or another reason. But it interfere not with the work of the second stage in my case, I use the screw on the lever to set levers hight. Normally according with the documentation I seems that nemrod used only two types of poppet. Respectfully Fred

Regarding some of my silvers poppets, one of them seems to have been shortened by cutting the pin π€

Are these long poppets Snark II single hose tilt valves?

Hello vance
Sure these long poppets are used in Nemrod single hose tilt valve reg. Snark II ore Snark II silver . In europe they where sold in big nummbers as cheap regulators .
Greetings Rainer
Edit : On the shaft you can see a littel dent that hold a littel zylinder witch hold the slim end of an spiral spring . The other end of the spring contacted the IP zylinder on the can side , not on the backside of the poppet as Snark III .

Hello vance
Its build similar to the SCOTT HYDRO-PAK
The parts are hidden unter a sheet metal , therefore no picture . Go to CG45 / scott hydro-pak / Fig. 9 I will use the scott nummbers : The dent on shaft part 85 is used to fix the littel zylinder part 90 (avoid to slide up) .
Greetings Rainer

Hello vance The dent on shaft part 85 is used to fix the littel zylinder part 90 (avoid to slide up) .Greetings Rainer The little cylinder would be called a "keeper" in English. The dent is called a "detent". Interesting. Thanks for the explanation, Rainer! As I said, I have no idea where I got 2 of these long LP seats. They must have been in a collection of junk I got somewhere.

Hello Fred
Your last picture looks that the venturi holes have been drilled bigger . Can you tell us about the modifications ?
Greetings Rainer

Hello Fred Your last picture looks that the venturi holes have been drilled bigger . Can you tell us about the modifications ? Greetings Rainer Hello Rainer , I think that this regulator had not be drilled bigger, I have photos of other peacock silver, I see no difference, and we can see the same drill trace, that are made in the factory. In my opinion this operation is very difficult because the holes have precise angle, so it is easy to ruined a boxy. This reg come from TSM , it was dusty, and need elbow oiI made a complete overhaul, last year I made two dive with this reg with OEM seat, it performed very well.
