Superlok Pressure Ratings

Superlok pressure ratings play a critical role in ensuring the safe and efficient operation of fluid systems. These ratings delineate the maximum pressure at which a Superlok fitting, valve, or tubing can operate without compromising its structural integrity or causing leaks.

These pressure ratings are determined through rigorous testing and adherence to industry standards, accounting for factors such as material composition, temperature, and the specific application requirements. They provide vital guidance for engineers, technicians, and operators in selecting the appropriate components for their systems.

  • When using Superlok Tube Fittings always select Stainless Steel tubing which is high quality (such as 304, 316, 316L and so on), fully annealed and seamless or welded, ASTM A269, A213 or equivalent. 
  • Allowable stress value between -20 and 100 (-28.9 ~ 37.8 ) is 19,500 psi
  • Safety factor is 4 (Ultimate tensile strength is 75,000 psi)
  • The above data is based on the minimum wall thickness and the maximum O. D. allowed by and under the standard of ASTM A269.
