Specifies the modulus of elasticity of the gasket material that occurs during loading and unloading of the gasket.

Typical units (depending on your unit system):

  • lb/in²

  • N/mm²

  • KPa

Several sources have shown this modulus to be somewhat higher than the initial tightening modulus for spiral wound metal gaskets. Typical values used for spiral wound metal gaskets are:

  • High End: 437500.0

  • Low End: 347000.0

Typical values are between 300,000 and 400,000 psi for spiral wound gaskets. The higher the modulus the greater the tendency for the software to predict leakage. Errors on the high side when estimating this value will lead to a more conservative design.
