NOTES:
All styles are furnished with an anti-stick parting agent as standard.
† For steam service above 150 psig, contact Engineering.
Refer to "Military Specifications" section under "Gasketing Terms" for order/inquiry requirements. To ensure receipt of product with the required DTL 24696 branding, certification will be
required; associated fees based on quantity.
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
5) Refer to Mill spec section under "Gasketing Terms" for order/inquiry requirements
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 1/32" (0.8mm) sheet thickness.
* Values do not constitute specification limits
All styles are furnished with an anti-stick parting agent as standard.
