The elusive stopper

[Maylar]

I had a standard white 2-hole #6-1/2 stopper that mysteriously disappeared from my brew room. All I'm seeing online is black ones sold by lab supplies outfits. Is this a rare duck? I need a new one.

Brew stores often sell white stoppers.

I would not use the black ones anywhere for brewing. I seriously doubt they're food grade.

Looks like @Bobby_M has quite a selection of white rubber stoppers, but I don't see double drilled ones:

Definitely rare. I've been looking for a solid 20 minutes and only found an asymmetrically drilled white #6.5 tapered stopper. On the up side, it claims lab' grade rubber...

That said, Morebeer has a silicone stopper double-drilled

Good luck!

Isn't that the downside for us... not being food grade?

 

[day_trippr]

Yeah, there's that. Better than no grade, I'd think. Wouldn't stop me if that's all that could be had though...

Cheers!

For what it's worth, I've been using black stoppers in my anti-suckback rig because they don't turn chalky and disintegrate when exposed to long-term Star-San solutions--or generally for that matter. I've mostly abandoned the white stoppers because they seem to lose pliability rather quickly, even when Star-San isn't involved.

Also, I'm under the impression that silicone is oxygen permeable. With that said, I still persist in using silicone blow off tubes (for their flexibility in my very confined fermentation fridges) and have not found any reason to abandon their use due to oxygen damage. Also, all my beer-facing stoppers are silicone. They seem longer lived than the white stoppers and I see no reason to abandon their use despite the purported oxygen threat.

Personally, I'd go with a silicone stopper.

Thank you. That's exactly what I'm looking for.

You can make your own custom stoppers by chucking up a piece of metal tubing in your drill and lubing it inside and out and just bore it through. You can make it go easier by cutting a notch in the end of the tubing with a hack saw, but it's not even necessary.

We used to make custom stoppers in the lab with these:


Kinda hard on the hands though. Definitely easier with lubricant and a drill.

This is what I bought your odds and ends SS tubing cuts for. I have put an edge on the tubing using a bench grinder. The lube is a good idea. Sometimes I have gotten a raggedy bore hole.
