Howdy,
For rubber seals of all types and weatherstripping, go to The Minor Rubber Co. Carrolton, TX or
www.minorrubber.com to puruse their catalog of diffenent types and cross sections.
To stop insidious leaking and freezing of door seals, I selected their refrigerator door seal with a compressive section and a labyrinth face. Believe me, no more problems with enclosure doors for Diesel and gas turbine gen sets from locations in the Arctic to those of Saudi Arabia.
Incidentally, the proper noun of Diesel should always be capitalized because it is the surname of R. Diesel, the German inventor of the Diesel engine.
Take care,
Maury
