Notes: 1. Based on Ansi RF Flanges at Garlock preferred torque. When approaching maximum pressure or continuous operating temperature, or 50%of maximum PXT, consult Garlock Engineering 1-800-448-6688.
2. ASTM F37B Sealability, milliliters/hour (1/32" thick) ASTM Fuel A (isooctane) Gasket load = 500 psi 3.5 N/mm2) Internal pressure = 9.8 psig (0.7 bar) Nitrogen: Gasket load = 3000 psi (20.7 N/mm2) Internal pressure = 30 psig (2 bar)
3. DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick) Gasket load = 4640 psi (32 N/mm2) Internal pressure = 580 psig (40 bar)
This is a general guide and should not be the sole means of selecting or rejecting this material.
