Glen,
the 818 and 819 nuts and sleeves are not meant to adapt 45 degree flares to
37, they are part of a standard 37 degree flare connection. I'm sure they'd
work with a 45 degree, but there's no good reason to use them that way.
Interesting Bill, it's my understanding that this is the purpose of using
them... that the sleeve compresses/deforms enough to make up the slight angle
difference.
FWIW, this is how I plumb all my systems, been doing it this way for years,
with 0 problems. I use a Blue Point double flare tool (45 degree), &
carefully inspect each flare for any slight burr that is sometimes formed on
the OD
between the 2 halves of the clamp. This is easily removed with a hand scraper.
They're virtually "bulletproof" in service, in my experience.
Question- If these are designed to be used on a 37 tube end flare, then what
would be the point of using them to begin with?
Uh oh, I hope this doesn't mean that I have to do a MAJOR recall (:-)!
Thanks for the input,
Glen
