Thanks for the link. That is the conclusion that I had reached, and I
receieved a response from Norgren stating it was obsolete and was in fact
G1/8. Which, if I am correct, is BSPP, 1/8, 28 TPI with a major diameter of
..383 . Got to see if I can machine me a fitting with a shoulder for a small
oring.

I've checked in a Norgren catalogue, but the part numbers don't quite line
up with what you have. You appear to be correct with the diameter &
stroke
designations, but the prefix doesn't match anything in my catalogue.
My suspicion is that the ports are 1/8 BSP.
For details of BSP threads, look here

I managed to come up with what I thought would be a good air cylinder to
mount on my 4x6 import horizontal saw to replace the spring. It is a
Norgen
N76025/125. Which I cannot find any documentation on. I think this is all
metric, as the 125 is the approximate stroke length in mm and the bore is
probably the 25. The problem lies in the ports. They are about the same
as
1/8 NPT, but the thread pitch is much finer and they are not tapered. Any
ideas what I am looking at here?
