American Seal and Packing manufactured by Neoprene® (Chloroprene) Gaskets. Trade Names: Neoprene (E.l. duPont), Butachlor (Ditsugil), Bayprene (Mobay)
Moderately resistant to petroleum products. Good Ozone and weather resistance. Good compression set. Excellent for sealing refrigeration fluids such as Freon®. Temperature range -65o F to +250o F.
Neoprene gasket material comes in four primary forms; closed cell (wet suit material), open cell, diaphragm, and homogeneous. Each of these three types have styles, colors and density variations that make them unique gasket materials.
Neoprene® Gaskets Materials
Neoprene Gasketing have 3 types. They are,
- Neoprene Gasket Material - Homogeneous
- Neoprene Gasket Material - Sponge
- Neoprene Gasket Material - Diaphragm

STYLE R-451 / R431 Black Closed Cell Sponge
Black neoprene closed cell (expanded) sponge gasket sheet. Tiny individual sealed
cells contain inert nitrogen gas to resist moisture, dirt and air even at cut edges. It is this unique structure that makes the closed cell sheet an insulator, sound and vibration damper and shock absorber. Compression deflection 5-13 PSI. Density 15-30 lbs/cubic foot. Water absorption 5% maximum. Temperature range -30°F to +150°F (continuous) (to 200°F intermittent). Tensile strength 150 PSI. Elongation 350%.
