Supermiata Radiator Drain Plug Seal
I've had a Supermiata crossflow radiator in my car for a few years now. I went to drain the coolant and noticed the seals on the two drain plugs have degraded and are leaking. I can't find a replacement online. Has anyone dealt with this before?
Right now i am just debating on sticking an o-ring in there.

A 3/8” bonded sealing washer (metal-backed rubber washer) works really well and is sold at any hardware store. Unlike a regular rubber washer or crush washer, they grip the bolt/plug tightly to provide a radial seal, and they are meant to seal well with minimal torque.
An O-ring won’t seal as well under the head of the bolt since it’s not designed to be squished like that. A normal copper crush washer will need a lot more torque on a plug that’s comically easy to strip.

I contacted Supermiata and received a lightning quick response. They recommend using an o-ring.
I like the idea of a bonded washer since an o-ring can squish out.
Looking at using something like this.
