REFRACTORY TUBES |
Refractory Product for Aluminum Die Casters- Durable, low cost, Resists erosion, will not contaminate your process. For tougher applications order Extra Heavy refractory coating (add 1/8" to OD as shown) Standard lengths: 12", 18", 21", 24", 30", and 36". Other lengths available upon request. *Add protection tube length as suffix, multiples of 6" (152.4 mm) stocked. Standard shank OD is 1 1/4" and Standard tip OD is 1 1/2". Refractory tube will not shatter like ceramic tubes and will not contaminate the metal like iron or stainless protection tubes. Silicon Carbide tip for rapid thermocouple response. |
