NOTES:
1) Based on ANSI RF flanges at our preferred torque. Maximum temperature of +1,000°F (+540°C) for GRAPH-LOCK® HT. Consult Garlock Applications Engineering when approaching maximum pressure or 50% of maximum PxT.
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 = 3,000 psi (20.7 N/mm2),
Internal pressure = 30 psig (2 bar)
3) 1,000 psi gasket load
4) DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick)
Nitrogen: Gasket load = 4,640 psi (32 N/mm2),
Internal pressure = 580 psig (40 bar)
5) 1/32" only (thicker gaskets have lower tensile due to metal construction)
