What could a "NBSF" pressure fitting be?
What could a "NBSF" pressure fitting be?
(OP)
I'm designing a portable field standard that will measure fluid pressures up to 40,000 psi. The Marketing guys have suggested a pressure fitting interface of 1/4" NBSF for the units that are rated between 15K psi and 40K psi. I've never heard of this type fitting and have been unable to turn anything up in searches for it.
Is there an obscure pressure fitting type by that description? Why would they want to use an obscure type (all our other high pressure instruments use HIP fittings for the interface of those pressures)? Could they have incorrectly transposed some of the letters?
Thanks for any help you can give -
Tim

Could it be a 1/4" Nominal Brand Specification Failure?

Only thing I've heard of even close is the National Building Specifications, some sorta setup in Britain where they have a central library of construction specs that can be used to build project specs from.

I'll throw out a guess: Nominal Pipe Size, Female or NPSF. Easy for some marketing weenie to hear "NBSF". I imagine this would be a threaded connection - but for such high pressures???

"NPSF" actually may be a good guess, nevertheless this abbreviation typically stands for "National Pipe, Straight, Fuel".

NTPF is a dry seal pipe thread, and will work at higher pressures, but I don’t think it would be the best choice at your pressure. Be sure to test what ever you chose.

Will it mean '1/4" Nominal Bore size, Female', similar as jte suggested, or
'1/4" Nominal Bore, Single Flanged' for high pressure connection.
