AGFS40 is a 40 durometer blue fluorosilicone rubber which is designed for gasket applications requiring a low compression set, excellent fuel and solvent resistance, and resistance to extreme temperatures. This fluorosilicone meets specifications, like MIL-R-25988 TY2 CL1 GR40 for aerospace and aeronautical applications and MIL-DTL-25988 TY2 CL1 GR40. Sheets of the rubber are capable of meeting AMS3325, AMS3326, AMS3327, AMS3328, AMS3329, AMS3330, and AMS3301. Atlantic Gasket’s AGFS40 endures a temperature range of -80°F (-62°C) to 500°F (260°C) and also has excellent resistance to oxidation, UV, ozone, and weathering.
AGFS40 blue fluorosilicone, offered by Atlantic Gasket, comes in a variety of durometers, thicknesses, colors, and widths. This fluorosilicone is 40 durometer but is also available at 50 durometer (AGFS50), 60 durometer (AGFS60), and 70 durometer (AGFS70) along with widths of up to 54” and thicknesses from .010” to .500”. AGFS40 has the ability to have a pressure sensitive adhesive laminated to this silicone rubber. Atlantic Gasket has the ability to slit AGFS40 to widths as narrow as ¼” or as wide as 54”. The fluorosilicone rubber can be cut to size for custom parts either using our high-speed die-cutting process or our high-precision waterjet-cutting machine for production quantities and/or prototype requirements.
