About Red Seal
Our company was founded by Sam Stryffeler in 1946 as the Durolet Manufacturing Company, the name being changed to Red Seal Electric Company in June of 1952. The first product offerings were electrical conduit insulating bushings and fittings supplied primarily to the steel industry.
These products are still manufactured today as part of our proprietary product line.
Red Seal Electric Company has evolved into a full service-oriented job shop for machining non-metallic materials, providing electrical, mechanical and thermal insulating products to an international customer base. We have grown by responding to our clients needs and welcoming new challenges and opportunities.
