But, basically, Spira is the name of a company run by George Kunkel out of North Hollywood, CA. George has been making variations on his fundamental gasket design for about 25 years. The Spira design is a helically wound, thin BeCu strip. The helix may be over air, solid neoprene, teflon, whatever. Various diameter helixes available. Must see the catalog and get a few samples. Call George at 818-764-8222 for design guide, catalog & freebies. No net site thst I know of. I generally like the stuff. Mounting sometimes takes a bit of thought. Electrical performance is equal or better than classic fingerstock, plus it is usually more mechanically robust and safer. Many other vendors of fingerstock.
