The Series 5300S Straight Female DIN x Female DIN heavy duty adapters in carbon steel are robust fittings designed for high-pressure fluid and hydraulic systems. These adapters feature DIN fittings with a 24° tapered throat angle inside the male threads. When the tube nut is tightened over the metric threads, it compresses a ferrule or cutting ring, creating a leak-proof seal and ensuring the assembly stays securely in place. The heavy-duty "S" pressure class of these fittings makes them ideal for demanding applications requiring high strength and durability. Made from carbon steel, these adapters offer superior performance and reliability in industrial environments, ensuring a strong and secure connection in medium to high-pressure systems.
