rubber plug on Sherwood 1st stage

[homerdoc]

I bought a used sherwood first and second stage at the dive shop. I needed to replace an ancient scuba pro on my Hooka rig. I was surprised when I found a rubber plug over a hole. The hole doesn't have any threads either. Any idea what it is? Okay to use as is? It breaths okay, and I suppose no issue since it is a hooka rig and will stay topside, but I have never seen a hole on a 1st stage that only has a rubber plug vs a threaded screw

Thanks.

Could it be a anchor point for disassembling ? The rubber plug just to avoid dirty or any other things going inside and start corrosion.
If it is not threaded I suppose it is a blind hole.

Do not remove the plug under any circumstances. It is the dry bleed system and is required for the regulator to work. If removed, they are almost impossible to replace correctly. Might as well throw it away.

Yes, it's Sherwood's proprietary/patented bleed valve. And I've personally found them harder to remove, than to get back in.You can buy replacements (for a ridiculous $16 +shipping), so they obviously are able to be reinstalled. Sherwood Regulator Kit Part One Way Bleed Valve 3106-6

For an Hooka rig, I had definitely kept using the ancient Scubapro...

well good, I popped it out and it popped right back in so I guess I am okay. the ancient scuba pro was just a greek tragedy from years and years of living at the lake. I did save it as a back-up however.

thanks for the replies

SP has only been around since the 1960ies-therefore cannot be ancient. :-D
