Torque specs for 3/4-14 NPSM threads in stainless steel and aluminum

[wxrocks]

Hi --

Does anyone have torque recommendations for a 3/4-14 NPSM thread for S.S. and Aluminum? Thanks! Eric

Is that a 3/4 NPT? I can't say that I am familiar with the NPSM call out. Perhaps Q has seen it before. I'll do some looking around.

EDIT: I just found what you're referring to. Straight pipe threads, not tapered. God bless Machinery's Handbook.

See if this is any help. If not, you may consider contacting the vendor.

Thanks for the help. This is a new thread for a project at work -- and I am going to be performing the testing to determine our final torque recommendation. I just wanted a starting point to have a figure to keep in mind while testing.
