OK, received my order from the o-ring store--great customer service, fast shipping, definitely would use them again.
As Ira mentioned separately, the SAE ring I detailed below is called a 007, and came in S70 durometer. The metric ones were simply identified as 1.5x3.0 and 1.5x4.0. The 3 mm one is clearly too small--it will fit but is stretched, and I doubt it will seal (but maybe). The 4 mm one is actually a hair too big--it is slightly loose around the breaker shaft. I think it will probably seal, but may leak around the shaft and/or have trouble seating centrally with the steam pressure. I believe the correct metric one (if it were available) would be 1.5x3.5. This vendor doesn't have that, but perhaps another would. The SAE one is absolutely perfect--snug fit, thick enough to seal easily, etc. And it costs 10 times less than the metric ones. Minimum order is 10, so if you need one, ping me privately. One really nice feature of theoringstore.com was that you just select the various sizes (ID, OD, cross section, etc) and their page then shows you what materials are available, what durometer, etc. It makes finding what you need really easy, since you don't need part numbers or anything like that. Appreciate all the help as always, and look forward to a non-hissing machine again for many years. :) best, Ben Thanks again John. I was also searching, and found http://www.theoringstore.com/ (who knew? What did we do before the internet???). In red silicon, I ordered the following sizes: SAE: 1/16 cross-section, 5/32 ID, 9/32 OD (I know this works--that's what the black ones are), minimum quantity 10 at $0.05 each (!) Metric: 1.5mm cross-section, 3mm ID (no OD can be specified), minimum qty 1, ordered 3, $0.58 each 1.5mm cross section, 4mm ID (no OD can be specified), min qty 1, ordered 3, $0.58 each. I ordered the metrics just because I'm curious, but obviously the SAE ones are dirt cheap and I now have a lifetime supply... Shipping was $5. Will report back when they arrive, as to which metric size was correct. I measure the old ring at about 4mm, and the breaker at 3.5mm. best, bmc Sent from my apple IIe On Aug 22, 2014, at 7:28, John Brinkman <[email protected]> wrote: > http://www.amazon.com/Silicone-O-Ring-70A-Durometer-Red/dp/B003SLE5LS#productDescription > > Just need the size > > Otherwise would try a hydraulics company, that's where I ended up > getting mine from. > > JohnB > > On Fri, Aug 22, 2014 at 4:18 PM, Benjamin McCafferty <[email protected]> wrote: >> Thanks John.
