O-Rings for WTC

09-30-2019, 10:57 AM

Hello,

I am ordering some O-Rings for a water tight container and have 4 choices.

Polyurethane
Black Nitrile Rubber
Red Silicone
Mechanical Fluorine

Can anyone help me decide which would be best?

Thank you for your help.

Black Nitrile is the most common. Also known as Buna-N. Don't go harder than 70 durometer.

Hi, I am using rubber rings Ø 4mm. Here it is necessary to precisely maintain the dimensions of the grooves where these rings will be installed.

What website are you going to for this information firma555? Looks like a good reference.

If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

Doing a quick search I found several o-ring calculators, here is one https://o-ring.info/en/tools/o-ring-groove-calculator/
