Is the TW connector gasket DIN 28450, polyurethane, type GSD suitable for use with 4" tank truck connections and an O-ring type TWO at temperatures from -20Â°C to +70Â°C?

Yes. The TW connector gasket DIN 28450, polyurethane, type GSD is specified for 4" TW (tank truck) connections using an O-ring type TWO and has an approximate service temperature range of â20Â°C to +70Â°C, so it is suitable for that application within those temperature limits.

Can the TW connector gasket DIN 28450, polyurethane, type GSD withstand chemical exposure common in tank truck loading at -20Â°C to +70Â°C?

TW connector gasket DIN 28450, polyurethane, type GSD can generally withstand typical chemical exposure encountered in tank truck loading within the stated temperature range of approximately -20Â°C to +70Â°C, but suitability depends on the specific chemicals involved. Polyurethane (PUR) offers good abrasion and mechanical resistance and performs well across that temperature span; however, it is sensitive to strong acids, strong bases, concentrated aromatic and chlorinated hydrocarbons, and some solvents which can cause swelling, softening or degradation. For fuel, many common hydrocarbons, and general petroleum products PUR is often acceptable, but for aggressive chemicals (e.g., concentrated acids/alkalis, ketones, chlorinated solvents) compatibility must be verified. Recommend checking chemical compatibility charts for polyurethane or conducting supplier-specific compatibility testing with the exact media, concentrations and exposure conditions before use.
