O-Ring Size for a Mr. Heater?

[mr_jman]

I'm hoping someone will be able to tell me what the size is for the O-ring used on the sunflower style Mr Heater?

Here is the part it is used on for reference.

I would think any good hardware store would have the size o-ring that you need

I believe it's a size #8.

O-Rings come in so many sizes ID,OD material width,In your case a propane leak would be dangerious.Just order one from a dealer.From the hardware store to small and it will leak.To large you'll crush and cut it it will leak.They dont come in numbered sizes.They come in ID measurement and thickness of the ring itself.You'll see 5-8 O-rings in 5/8 inch ID each will be different thickness

wrong. They do come in numbered sizes.

This will help.

Don't know size but they sell packs of them in the propane accessories section of many hardware stores for about $2.50 for a pack of 20 or so (Mr. Heater Part #F273786).
