Made of 440 grade stainless, was included with parts for a keezer so may be related to beer brewing, 1/4 in dia.

A beefy handlebar for a beetle's motorcycle.

(Honestly have no idea.)

To big for a beetle, maybe Crazy Frog’s handle bar?

Looks like the gas-in stub that comes off the other end of the gas tap inside the keg. I was using Cornelius style kegs though, and one end of the tubes was always flared for the o-ring to seat in.

These are solid, not a tube.

Looks like a locking pin where the groove sits against a sprung ball bearing. Easy enough to insert and release but prevents two parts from moving in a perpendicular path to the pin. Can be used to stop pivoting too.

Makes me think of the kind of pin that you pull out to lift up the seat of a rowing machine to store it vertically.

The groove defiantly looks like a detent, the kegs do have a lever that lifts to open them but there is no hole for this to fit.

Looks like a shear pin, but bent for some reason? Is it hollow inside?

[–] [email protected] 3 points 4 weeks ago (1 children)

Nope, solid. The angle is about 25° and is the same on both sides. I have four of them all identical. The Keezer is a 4 keg system but nothing I can find shows these as a part for the kegs, regulators, beer faucets, etc.

If it's solid, I got nothin'.

I was going to say it looks like a metal straw used for drinking yerba mate, but without the strainer on the end.

Obviously a solid straw isn't getting you far.

It's for people who are trying to quit drinking?

Was this a kit for a keezer or just included with some parts you picked up?

[–] [email protected] 2 points 4 weeks ago

It was a used Keezer I picked up from Craig's list, I took my time disassembling, cleaning, and reassembling / rewiring so now the seller is no longer contactable to ask.

Maybe you run the middle part along something like a glass edge? I have no clue

[–] [email protected] 2 points 4 weeks ago

Maybe goes inside the tap to reduce foam? I'm just spit balling.

Let me preface this with I know nothing about beer making and had never heard the word keezer before today. Could it be an extension for the handle, so you could have a different orientation than the standard?

[–] [email protected] 2 points 4 weeks ago

The handles are threaded and these are not.

Looks like an agitator for a magnetic stirring device. I've seen similar used for the inside of mash tuns.

Sinct it's SS, you're going to have some trouble with the "magnetic" bit.

[–] [email protected] 1 points 4 weeks ago (2 children)

A lot of stainless is still magnetic. You have to get above 430 grade stainless to be non-magnetic.

[–] [email protected] 2 points 4 weeks ago

IDK where you get that statement from. 304 and 316, which are the most common grades, have very, very slight paramagnetic properties. OPs 440 might be slightly magnetic if annealed, but that's not what would be typically sold. In it's hardened state, it's not magnetic.

It looks like 440 grade stainless and is non-magnetic. It tried with a very strong Neodymium magnet. Also most mash tuns i’ve seen are either made from a cooler, copper or stainless pot and stirred with a motor in the lid, if they are stirred at all, usually just the sparging arm rotates. I don't think I’ve ever seen one with a magnetic stirrer not even sure how that would work through the grains.
