*This style is not the preferred choice for steam service, but is successful when adequately compressed. Minimum recommended assembly stress = 4,800 psi. Preferred assembly stress = 6,000-10,000 psi. Gasket thickness of 1/16″ strongly preferred. Retorque the bolts/studs prior to pressurizing the assembly. For saturated steam above 150 psig or superheated steam, consult the Gasket Supply sales team.
