Local hardware store?

My local Ace Hardware store has a whole wall full of O-rings.
All different diameters and different thicknesses.

RJX actually make replacements, they would be listed for their 90 size muffler.
I have sized them up, they are exactly the same size as the Hatori ones.

For the love of the hobby

The O-rings I can get locally at Ace Hardware are made by Danco. (I have one in the package right here in front of me)
I can't find any indication on the package or the internet that says they're high temp.

If there is an industrial park in your area, I would bet there is a fastener store that carries tons of different O-Rings.

I get all the bearings for my helis from a local shop here.

Order Viton O-ring from McMaster-Carr

They come in a pack of 25 for $6.75. I've been using them for years on the Hatori mufflers.

Those are the standard ones which work fine but the item I listed above are the milspec ones which I feel better about. Either one will work just fine.

As you are looking local;

Use the part number posted above and go into a GOOD auto parts / boating / etc store and tell them what you need. You want the same physical size and same durometer. Viton should be best, silicone are just fine (I've been using them) and considering you want them for the weekend, anything that will last a couple of flights is better than none, right?

Just match the size and durometer - it's listed on McMaster based on the above posts.

When I say good, I mean like NAPA or a mom-n-pop race/machine shop, none of this Checker BS.

Thanks for the info, I got some O rings from NAPA today, they were not sure if it was the same material, I tested on the oven for 50 minutes at 400F, together with the old o ring and it looks like it wored ok, I'll try them tomorrow.

Anyone have any experience using the Viton O-rings and them being so hard they wear out the aluminum? I used to use the Viton o-rings in my R/C boat exhaust. It was a water cooled Hanson exhaust and it wore out the aluminum badly after a few runs due to the hardness of the Viton combined with the vibration of the Zenoah G26. Cheap aluminum I guess?

Hydraulic or farm implement places carry these rings, when through same thing and ended up finding them at a farm implement store, just a thought.

...Once upon a time there were Nitros, flybars and frequency pins...
