HP gauge fitting

[Topcat414]

I have an old Nemrod pressure gauge (actually several) that has a 9/16-18 male thread on it, not a 7/16-20 thread like current gauges. I have been looking all over to find a fitting to adapt form 9/16-18 male to 7/17-20 male. That is the fitting would be 9/16 female with a 7/16 male to accept a spool and standard hp hose.

Any ideas?

Are you sure it's 9/16-18 ? Some of the Nemrod stuff was metric, the OPV's on their double hose regs for example. They are M10x1 which is close to the the common 3/8-24 and can be mistaken for it if you are not looking real close.. I don't know for sure but it's worth a close look before spending too much time or money on parts.

It fits a LP hose and the da hooka port cap very cleanly. I did suspect metric at first as I have found the same on the nemrod double hoses. But I does not bind on the mating female 9/16 at all.

I know it would be a bit halfass but you might could use this 9/16 to 3/8 then a 3/8 to 7/16 adapter behind it. 9/16 Female to 3/8 Male Adapter , Piranha Dive Shop |

By the way, if you have never ordered from Piranha, he is great to work with.
