Benefits
Notes:
1
Based on ANSI RF flanges at our
preferred torque. When approaching
maximum pressure, continuous operat-
ing temperature, minimum temperature
or 50% of maximum PxT, consult Garlock
Engineering.

ASTM F37B Sealability, milliliters/hour
(1/32" thick)
ASTM Fuel A (isooctane):
Gasket load = 500 psi (3.5 N/mm

),
Internal pressure = 9.8 psig (0.7 bar)
Nitrogen:
Gasket load = 3,000 psi (20.7 N/mm
2
),
Internal pressure = 30 psig (2 bar)

DIN 3535 Part 4 Gas Permeability,
cc/min. (1/16" thick)
Nitrogen:
Gasket load = 4,640 psi (32 N/mm

),
Internal pressure = 580 psig (40 bar)

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 pres-
surizing the assembly. Never
retorque a pressurized assembly.
• If the service is superheated steam,
contact Applications Engineering.
Benefits
Ideal for ethanol industry
¦
Designed to excel in saturated steam, water, oils,
fuels—over 90% of industry applications
High performance
¦
Inorganic fiber gasketing offers excellent thermal sta-
bility with minimal weight loss
¦
Reduced creep relaxation and improved torque reten-
tion ensure optimal sealability
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;

Ultra-tight seal in water and oil applications
¦
Proprietary formulation creates additional gasket load
when the gasket comes in contact with oil or water
¦
Twice as compressible as standard fiber gaskets -
conforms to irregular surfaces
Versatile
¦
Stops leakage in:
• Gear boxes
• Compressors
• Pumps
• Lube oil systems
• Access covers
Thickness measured with a 9 oz. weight be-
fore immersion and 3 oz. after immersion.
LEAK-GARD™ Style 3750 is also
available exclusively for oil-swell
applications.
