Sherwood something.

Sun Oct 20, 2019 9:21 pm

My former boat partner and dive buddy just got hauled off to the old-folks home where they will keep him comfortable in his last days. He gave me his current regulator, (the really cool ones apparenty consigned to the trash dump by his helpful relatives who cleaned out his condo for him). I know zero about Sherwoods.

1. What Sherwood model is it?

2. Are parts available?

3. Is it worth fixing up?

Thanks,

Mark

I think it's a SRB-5700 Oasis ( I have a manual). Parts should be available and it's a good reg. By the way you do know Sherwoods are SUPPOSED to leak don't you ?? One of the "port plugs" should be a rubber stopper, a small stream of bubbles SHOULD come out of it if it's working properly.

Thanks Herman. Good to know about the bubbles. Like I said, I know zero about the brand.

"Sherwood, the leaking reg" :)
It's part of their environmental sealing feature and IMO, a pretty good one. You will notice there are no ambient holes like on most piston regs. Instead they bleed a tiny amount of air into the spring chamber and then allow it to escape via the rubber one way valve. This keeps the spring chamber at ambient pressure, slightly over actually, without allowing water to get to the spring. If you use a SW for a pony bottle, it should always have the valve open and charged, otherwise water may leak into the spring chamber and make a mess since you can't easily rinse it out. I wouldn't soak them unpressurized for the same reason.

Herman thank you for for the info as well. I have a couple of them that were part of a LDS buy out I recently did. I was puzzled about the rubber plug.

Sherwoods often scare new divers when they see a small stream of bubbles coming from the reg. That sealing system and the floating HP orifice (on balanced models....basically all except the Brut) make the Sherwood an odd reg but they work well and are reliable.
Don't use it if there is NOT a small stream of bubbles coming from the rubber plug.
