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
NOTES:
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)
4Saturated 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
5Refer to Mill spec section under "Gasketing Terms" for order/inquiry requirements All styles are furnished with an anti-stick parting agent as standard.
