PREDATOR 1330 gaskets and seals are made using a NSF 61 approved formulation of EPDM (Ethylene Propylene Diene Monomer) to meet the requirements of ASTM D1330-04. This compound is well-suited for creating ANSI/AWWA flange gaskets and custom molded seals used in potable (drinking) water applications.
PREDATOR 1330 is available in molded sheets, which are suitable for flat gasket production. Additionally, specialty shapes and sizes can be achieved through compression and injection molds for exclusive OEM applications in pumps, valves, and filtration products. PREDATOR 1330 can also be extruded into extended lengths, such as tubing, cord, or custom profile shapes.

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.
