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

The recommended thread torque specification for 3/4-14 NPSM stainless steel is 125-150 ft-lbs.
The recommended thread torque specification for 3/4-14 NPSM aluminum is 50-75 ft-lbs.
The difference in thread torque specifications between stainless steel and aluminum is due to the difference in strength and hardness of the materials. Stainless steel is a stronger and harder material compared to aluminum, therefore a higher torque is required to achieve the same level of tightness.
If the recommended thread torque is not followed, it can result in a loose or insecure connection, which can lead to leaks or failure of the threaded joint. It can also cause damage to the threads and compromise the integrity of the part.
Yes, there are other factors to consider when using these thread torque specifications, such as the condition of the threads, lubrication, and the use of a torque wrench. It is important to follow the manufacturer's instructions and guidelines for proper installation and torque specifications.
