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

1

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.

2

These styles are not preferred choices for steam service, but are successful when adequately compressed 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 or superheated steam, consult Garlock Engineering.

3

Indicates electric current arced around and not through the gasket. Dielectric strength is higher than indicated.
