I am looking to purchase exhaust clamps made from 304 SS and made like the Torca Accuseal Clamps. These are heavy duty clamps in sizes ranging from 2" dia to 3.5" dia. The actual bands are .070" thick and are 1.25" wide. The fasteners are made of a stronger material with a splined bolt and spacer, and are coated for rust resistance. Each dia. specified actually will clamp over a tube with a diameter equal to the nominal size + .150 dia -.150 dia. approximately. I am interested in buying these in quantities of 2,000 to 5,000 of each size per order.
