Since our founding in 1946 by Sam Stryffeler as Durolet Manufacturing Company—later becoming Red Seal Electric Company in 1952—we have been at the forefront of innovation in electrical insulation and composite material fabrication. Our first product offerings were proprietary electrical insulation devices for the open wiring systems utilized in steel mills. Since that time, Red Seal has grown into a full-scale manufacturing and machining operation, serving industries worldwide. Wherever thermal, electrical, or mechanical insulation is required, Red Seal delivers solutions that set the industry standard. Our extensive in-house capabilities allow us to deliver complex, custom-machined parts with tight tolerances.
