Built from multiple embossed stainless steel layers including AMP coatings and an uncoated center shim, the outer layers are coated with Viton on both sides (heat resistant to 250 C/482 F). The MLS design provides reliable sealing without sealants, accommodates aluminum-to-aluminum or aluminum-to-cast-iron combinations, and promotes even load distribution while reducing clamp load and bore distortion.
