Notes:
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.
* Values do not constitute specification Limits
1
See Garlock chemical resistance guide.
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.
3
Indicates current arced around and not through gasket. Dielectric higher than indicated unless otherwise mentioned.
4
These values are from style 2950. Style 2900 has higher values.
