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 1/16" (1.6mm) sheet thickness.
* Values do not constitute specification limits All styles are furnished with an anti-stick parting agent as standard.

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 Engineering.
² ASTM F37B Sealability
ASTM Fuel A (isooctane):
- Gasket load = 500 psi (3.5 N/mm2), Int. pressure = 9.8 psig (0.7 bar)
Nitrogen:
- Gasket load = 3,000 psi (20.7 N/mm2), Int. pressure = 30 psig (2 bar)
³ DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick)
Nitrogen:
- Gasket load = 4,640 psi (32 N/mm2), Int. pressure = 580 psig (40 bar)
⁴ Saturated steam service guidelines:
> For optimal performance, use thinner gaskets when possible.
> Minimum recommended assembly stress = 4,800 psi.
> Preferred assembly stress = 6,000 psi to 10,000 psi.
> Retorque the bolts/studs prior to pressurizing the assembly.
> If the service is superheated steam, contact Applications Engineering.
