Where to find??

Guys
I am looking for the correct size of the Barrel "O" Rings that fit the Seneca/Storm Rider type rifles, and where to buy them, as there seems to be a lack of any supplies for sale.

The following measurement are from the Barrel dimensions:
Depth = .044"
Width = .040"
Inside diameter = .340"
Outside diameter = .384"

Metric spec's (Not sure these are correct measurements) = I don't speak metric...
Depth = 1.05mm/1.10mm ??
Width = 1.00mm/1.05mm ??
Inside diameter = 8.60mm/8.70 mm ??
Outside diameter = 9.75mm/9.80 mm ??

Is there a site or place to but some?
Tia,

you mean the 2 Oring that are on the barrel where it slides into the breech
0.80mm x 8.4mm ID
so, i bought some years ago and they were 0.21 each and now they are $1.03 each
shop around but you will find they are a hard size to find and 1mm CS will not work i tried that

O-ring Store, O-rings and More, Mcmaster-Carr. All 3 will have them. Only measurements you need is Inner Diameter & thickness (cross section). Search metric rings.

If you know the exact size you need and I have them, I'd be happy to send some. I've amassed quite a few, large o-ring kits over the years.
Let me know what you need and I'll check to see if I have them.

Gerry52 hit the nail on the head. O-rings require 2 dimensions the inside diameter and the cross section. All O-rings are listed and stocked on these two dimensions. KISS does still apply, if we specify the ID and the cross section the OD is redundant. There are a couple more things we need to know beyond the two critical dimensions.
Compound: Most O-rings are Buna-N, also known as Neoprene.
Durometer: The "hardness" of the O-ring compound. O-rings for high pressure applications may be "harder" to resist extrusion.
There are right about one zillion O-ring compounds hyperbole alert but there are actually thousands of different O-ring compounds. For our airgun purposes the vast majority will be Buna N.
IMO I would rather pay double or triple the price for the O-rings from the gun manufacturer, just to assure those couple of other specs are correct. Double the price on an O-ring might make it a dime rather than a nickel.
