SPECIFICATIONS FIGURE NBG (R & Z) NUT, BOLT AND GASKET KIT
RED RUBBER & ZINC PLATED CARBON STEEL
The FNW NBG (R & Z) Nut, Bolt, and Gasket Kit features Red Rubber gaskets and Zinc Plated Carbon Steel hardware. The kit is designed for use with 150# pressure class flanges.
Red rubber gaskets are manufactured from styrene-butadiene rubber (SBR). This synthetic material was developed as an alternative to natural rubbers. The red rubber gaskets are recommended for service in cold and hot water, air, and some weak acids. They offer little resistance to ozone and to the majority of hydrocarbons. They should not be used with strong acids, oils, grease and chlorates.
Chlorate refers only to chlorine in the +5 oxidation state, or chlorate ion. The chlorate ion is a byproduct of the disinfection process used to treat drinking water. It is formed when sodium hypochlorite or chlorine dioxide are used in the treatment process. SBR is not recommended for environments with elevated levels of chlorates or chlorines. Chlorine chemically attacks SBR very aggressively, which can create a potential leak path.
