Guess I need a lesson in pipe measurement. Got the regulator today and
the diameter of the input threads is 1.25" the diameter of the pipe I
wanted to connect it to is 1". The box says 1" and the regulator is
stamped 1". It's my fault probably due to my ignorance on the matter. I
emailed the supplier asking if I should request a RMA or get fittings.
You can get reducer fittings. Be aware that threaded pipe is sized by the
inside so a "1 inch" pipe is about 1.25" on the outside. What you need is a
couple of 1" to 3/4" reducer bushings. If that makes the unit too long, try
to exchange it for a 3/4" regulator. Be careful not to get it installed
backwards by mistake.
