NAM 37C Compressed Fiber Gasketing

NAM 37C Compressed Fiber Gasketing

NSF-61 Certified ARAMID/NBR (GREEN)

Peak Temperature: 572°F (300°C)
Continuous Temperature: 428°F (220°C)
Continuous Temperature: 320°F (160°C)
with steam

Operating Pressure: 1137 PSI (80 Kg / cm²)

M Value: 2.5 (N/mm²)
Y Value: 25 (N/mm²)

The m = maintenance factor which provides the additional pre-load needed in the flange fasteners to maintain the compressive load on gasket after internal pressure applied to a joint. The y= minimum design seating stress on the contact area of the gasket that is required to provide a seal at an internal pressure of 0.14 bar Y=W/A1, where W is total fastener force in N and A1 is gasket area in mm².
