RUGGED. for superheated pressures BELMONT 4040 Here is a steam valve packing that per forms well on superheated steam tem peratures as high as 800 F. Inconel wire-inserted asbestos is braided over a non-metallic plastic core to com bine strength for high pressures with compressibility for good sealing charac teristics. Supplied square in cross section, in sizes and up. Ask your U.S. Gasket-Belmont Packing Distributor or write for Catalog No. 56. Belmont Packing & Rubber Co.
