They provide over 100-db attenuation against EMI/RFI. They measure from 0.06 to 0.15-in. high, and will close gaps from 0.030 to 0.130 in. Stick-on gaskets provide fast and reliable installation and can be used in temperatures from -67 to 300°F. One side of the Hook-on gaskets fits over flanges so they are more secure. The smooth-to-the-touch gaskets work in bidirectional applications and require low closing forces. There's also an optional DiamondBack (dB) textured surface for high-frequency applications.
