Terminal Gasket Assembly

The TGA consists of two ceramic fiber washers, one steel washer, and a spring.

The TGA is used as an alternative to packing ceramic fiber insulation around the Starbar cold end. Ceramic fiber insulation is often used at the cold face of the furnace to help reduce furnace energy losses.

There are advantages to using the TGA rather than packing ceramic fiber insulation around the Starbar. Because the TGA is spring-loaded it allows the Starbar freedom of movement. If ceramic fiber is packed too tightly it can cause tremendous physical stresses to be exerted to the Starbars, possibly leading to failures due to breakage. Freedom of movement is important because there is movement between the Starbars and the furnace walls created by different thermal expansion rates.

Installing of TGA is also quicker than packing with ceramic fiber.

Neither of these methods are intended to be an atmosphere seal. It is to help reduce radiant energy losses, and to a smaller degree some convection heat losses.

There are two free spring lengths, 1 inch (25 mm) and 3 inches (75 mm). The last digit of the part number is used to call out the free spring length.
