Skip to the bottom if you want to bypass the boring details. Yes, free 0-rings!
I like to carry a reasonably complete repair kit. Having recently received one of Roger Caffin's winter stoves I set out looking for a set of o-rings. I found nothing metric at the local big box hardware store so I went online and found a couple of sources. The first source had very large minimum orders, the second source required orders that were quasi-reasonable. So, I ordered from #2 and for about $25 I have more than a lifetime supply for one person. Better that they be used than be passed on to my heirs,
I would like to give away the following kits to BPL members and lifetime members.*
Viton Fluoroelastomer composition in these sizes:
Quantity one 7 X 3 mm inside diameter X thickness
Quantity two 5 X 1.5
Quantity one 3 X 1.5
Quantity one 3 X 2.0
Total five pieces.
Trivia: Different vendors seem to specify the sizes differently, i.e., some refer to the outside diameters of the four rings which are 13, 8, 6, 7 mm, respectively. The vendor from whom I purchased specified the "7 X 3" as "3 X 7" on the packaging.
From the Stove Manual: "The O-rings are usually Viton (but see Extreme Cold). The ‘big fat’ O-ring visible in the canister connector is an OR7x3 size. The O-rings inside the canister connector body, on the hose end and on the white valve, are both OR5x1.5 . The small O-ring sealing the hose into the stove body is an OR3x1.5 . The O-ring on the needle valve seems to be an OR3x2."
The o-rings were received in quantities of 25 except for the 7 X 3 which arrived in a 10 pack. I would like to keep 3 sets for myself, so the first 7 requests will get the full complement and the succeeding 2 requests will receive the three smaller o-rings only. The last 13 requests will receive the 3mm I.D. o-rings only. Hope I did the math correctly!
I have not completely torn apart the stove to verify that what I have is in fact what is needed. I did measure some but not all the o-rings in the stove itself but have not put a caliper on the replacements. Faith!
I advise feeling the package contents to locate the o-rings before cutting it open along the edges. Don't want to damage an o-ring! Comes with a small zipper baggie for storage. Use some care if you rip it open or you may experience something akin to a potato chip bag explosion.
*PM your address to me and I will send them to you via USPS. Limit one set per person. USA addresses preferred, please, but I will not exclude anybody unless the shipping cost is outrageous. FWIW shipping in an envelope stateside costs $0.70. Looks like international shipping is $1.36 to Canada and most places (?) out of the country. The stuffed envelope weighs less than 0.5 ounce.
Edit Update: All of the complete sets have been claimed. Partial sets are available.
