Anderson metals makes the best fitting for the poly flo I have found so far and now I have a correction on this last e mail . Mcmaster called and said they wont carry them after they said they would order them today so I went back to spruce and found that they carry the correct one  now. The reason I started this adventure was spruce sold the parker fitting and  changed up to the Andersons a year ago I’m guessing  . I also asked the Anderson’s sales rep to tell me all the distributors on the west coast and spruce didn’t come up at all even  after I asked them why spruce wasn’t part of the retail group  anyway  I have been had by the goat rope  on this one   Bill Maddox
