ThermoFab Bulb Seals and Kiln Car Packings are manufactured to client specifications, from a wide variety of materials, to suit all applications. The Bulb Filler can be made from silicone, stainless steel mesh, glass rope, ceramic rope or a soft core felt. A fabric is used around the filler to encapsulate the bulb and create a tail section where the ‘Tadpole Seal’ is clamped. ThermoFab’s specialised Kiln Car Packings are manufactured to last in excess of two years.
