Notes:
3
Minimum recommended assembly stress = 4, 800psi. Preferred assembly stress = 6, 000-10, 000psi. Gasket thickness of 1/ 16 " strongly preferred.
Retorque the bolts/ studs prior to pressurizing the assembly. For saturated steam above 150psig, consult Garlock Engineering.
4
This " M " value, based on ambient temperature leakage with nitrogen, is high. Field experience has shown that lower values would be workable in
elevated temperatures. Consult Applications Engineering.

This is a general guide and should not be the sole means of selecting or rejecting this material. ASTM test results in accordance with ASTM F-104;
properties based on 1/ 32 " ( 0.8mm) sheet thickness unless otherwise mentioned.

2 Based on ANSI RF flanges at our preferred torque. When approaching maximum pressure, continuous operating temperature, minimum temperature or
50% of maximum PxT, consult Garlock Applications Engineering. Minimum temperature rating is conservative.
