Well I couldn't really find the info anywhere when I was looking so I figured I would make a post. I had contacted MoreBeer regarding getting a replacement for the spring in the PRV of my counter pressure filler. I was told a part number (I could order it, but only via phone). The reason I needed to replace it was because it was not stainless...and it had rusted. When you're filling bottles you will inevitably get some beer in there during filling. If you sanitize the whole filler it will also get sanitizer in there. These both cause it to rust. Logic suggests it should be a stainless spring in there. So I looked around to see if anyone had listed the part number and couldn't find it.. so I measured it out and bought some replacements from McMaster. Was worried they might not be quite right but they are a perfect fit.
part number # 1986K92 at this time 4.76 for 6 of them (though it's stainless and will never need to be replaced most likely)
