O-RINGS

Post by Maltose Parrot »

Does anyone know of somewhere local that might have a good selection of the reddish orange silicone o-rings? I need to try a couple different sizes and don't want to buy several packs fo the ones I won't need.

Thanx!

I ordered a bunch from McMaster-Carr for my corny kegs. DrDually gave me the part #s.

I have a bunch of the AS568A-111 if you need some.. check out AS568A-111 for gas post o-rings...

The o-rings I need are for the bulkhead fittings on my kettles. I used a punch tool to cut the holes, and it proved to be just a hair too large to form a tight seal using the o-rings I got with the kit. I wanted something with a bit larger cross section to try.

Tony, you might not want an o-ring, but a silicone gasket instead.
Check out these: http://www.bargainfittings.com/index.ph ... uct_id=189

Combine the gasket ring and a stainless washer and you get a lot of surface contact. There's also an even larger red version on their site.

You can check with Derrin if he has these, but I didn't see them on the website.

The weldless bulkhead fittings Derrin has worked great for my tad-too-large hole I drilled into my kettle. I know you asked specifically about o-rings only, but if you don't find a good fit, these might help. http://www.brewershardware.com/Weldless-Fittings/
