Sorry I don't have any more left. Amazon.com carries packs of these with free shipping if you have Amazon Prime membership.

(Silicon is the same as OEM. Viton is possibly more durable, but the low temp rating is only down to -15F )


140 Silicone O-Ring (pack of 25) $10.05
http://www.amazon.com/gp/product/B000FN0ZHA

140 Viton O-Ring(pack of 10) $6.63

I used the silicon one for mine, but both are likely OK. Silicon is the same material used on the original DISA. Viton is slightly harder (apply some oil/lube before installation) and is worse in terms of it's resistance to cold (-15F low limit), but has better high temp resistance. Silicon has good static sealing properties, and is reasonably good in terms of its temperature range for both heat and cold.

how well did these fit? Did you have to tighten the bolt to push the disa in to the manifold or did they go in by hand?

I didn't have to force it to install. This is the right ring size by consensus in these forums, and of the 20+ rings I had sold all of the feedback was positive.

I placed an order for these today, and I will extend the same offer. It will be a short time before they arrive, because Amazon only says that they will be shipped in 2-3 weeks. If you can wait, I will be glad to send them when I have them. Just PM me.

For everyone who has inquired about this, I got a notification from Amazon today, stating that I can expect these on 3/12. If you sent me a PM, then there is no need to send another. I have saved them all. If you are interested in one of these, I will have 50 of them as of 3/12.

Those are not silicone O-Rings, they are Buna-N, which is not the best material for this application.
Also, there are rules on here about pissing on someone's "For Sale" thread with info such as "You can buy it cheaper/better here".

The OP already completed his sale and the recent questions were about DISA seal sources.

There is no reason silicone o-rings are necessary or even advantageous for this application.

No, I took over the sale of the O-rings, which the OP approved, and if you read all of the posts, you would see that. So, my advice stands. So, jumping in on someone's sale thread is considered bad form on this site, and is against the rules. Since you are new, I thought I would point this out to you politely. I guess that did not work.
