where to order o- rings?

I always buy from The Oring Store. Those sizes seem rather odd, so they might not have that size??

O-ring facts:
NRB Nitrile Rubber = Cheap, poor resistance to ozone, weather & aging
HNBR Nitrile Rubber = Improved properties compared to NBR
NBR 70 (90) Shore durometer value. Measure of hardness of material. Resistance to permanent indentation

Eddie I have been putting together a list of o-ring sizes from the O-Ring Store to use in the Wildcat. I have found some of them in metric sizes but most I have to found in the equivalent sizes in the AS568 chart the 6.35mm ID x 1.27mm width or cross section or cs equals 0.24" x 0.050" that is approx. 1/4" x 3/64". The problem is I see no size on the AS568 chart that comes close to that. Still looking myself for that size myself.

Eddie if you need the orings right now maybe try some NBR 70 1/4" ID by 1/16" width and see if the 1/16" will squeeze down some and work. I could be completely wrong here but it might be worth a try. Bill

Don't know what part of the States you live in or if you do,but Motion Industries has all type of o-ring and great to deal with. They do ship and no we don't for the them. We do a lot of business with them

Did you they try one of there other stores? I'll try one of our stores Monday when we get back to work. Try their web sight

I forgot where I did but I bought a assortment of different sizes.

What did we come up with on the Wildcat o-rings. Is there replacements for all of them??

I wish everyone had a listing of proper replacement O-rings like that.

MSC and/or McMaster Carr may well be a source

Bought just the same a while back. Amazon or e-bay I think.
But I just have them in back hand for a rainy day, and haven't used any of them because I am not sure if the quality is up there.
So: anyone used them on their Pcp's?

Well for the outer orings on the barrel and the fill probe I found at home depot, but I ended up buying the breech oring from AOA. $2 each, $ 10 minimum and $7 shipping. So $17 for 5 breech orings. I haven't needed to replace any others so far, knock on wood.

Do you have the sizes for these o-rings?? the ones you found at home depot? Breech Oring buying like that is just not right

I always buy Venton High pressure high heat resistant, long wear orings from http://www.oringsandmore.com/. Seem to always have what I need. I guess the buena's are good for air guns too. Vintons are better. I built an electric motorize contraption auto pump for my Benjamin pump. Does full Pump stroke in 55 sec. no rest in between strokes, gets a little hot but the Vintons hold up fine.

Pretty sure the Vintons are made from nitril. Use them for the 3rtd stage oring that always get destroyed from heat. These last way longer.
