DIN 40 BAR Flange Supplier & Exporter

DIN 40 BAR Flanges (PN40) – High-Pressure DIN-Standard Flanges

DIN 40 BAR flanges, also known as PN40 flanges, are pressure-rated components used to connect pipes, valves, and equipment under operating pressures up to 40 bar (580 psi). These flanges are engineered to DIN standards and are essential for industrial systems that operate under high-pressure conditions. Werner Flanges Inc. manufactures DIN 40 BAR flanges with precision tolerances and durable finishes to meet stringent project requirements.
