They have lots more than these, too.

Most any hardware store. Try Home Depot, Lowes, local Ace and so on.

I'd be extremely surprised if any of the chain hardware stores carried 1.0mm cross section o-rings.

Take your pick from different material types below. Not affiliated with this outfit but have used them in the past for my regular E46 plumbing work.

Viton : Viton(R)/FKM O-ring 6 x 1mm Price for 25 pcs | eBay
Silicone : Silicone O-rings 6 x 1mm Price for 10 pcs | eBay
Buna: Metric Buna O-rings 6 x 1mm Price for 50 pcs | eBay

I agree with Jeff, the thinnest o-rings I found from local hardware stores are at least 2mm or 5/64" thick.

Try auto parts or industrial supply stores, maybe small engine repair shops.

I bought a kit from the tool table a local flea market.
It is a carry box with about 20 of each of a range of about 10 or 15 sizes.

Thanks guys - especially ej25

Yeah, the 1mm cross-section eliminates most hardware stores. Did find them yesterday at oringstore which was the same ebay seller.

Need them to replace the worn out material on a Stellavox Sp supply reel clutch.

When there´s oil included, make sure their material is Silicone or EPDM. They can withstand grease, oil and all kind of solvents and will last longer. Standard rubber might be desolved after only a few months

This is about right, and will last for 100,000 miles!

There's a lot of o-ring rubber formulations so it very much depends on the solvents at play. Best to look at something like Cole-Parmer's chemical compatibility chart if there's ever a worry. With 1mm CS o rings like this, I'd be thinking an NBR would be the best bet.

Basic Buna-N o-rings are very robust, and are very resistant to oil and grease.

Here's a short version of my take on the compounds:

• EPDM: good allround compound
• Buna/Nitrile: good allround compound except in presence of higher oxygen percentage
• Viton: less good in abrasion resistance
• Silicone: very poor shelf life: I have some that turned brittle after only a few years.

There's a big thread over at scubaboard, but that's probably overkill for audio.
