DN7.4 Quick-Connect Socket with Valve, Threaded Hardened Steel, 1300 Series

The universal quick coupling socket DN7.4 with valve is a compact and highly efficient solution for pneumatic systems, designed for reliable operation with compressed air and gases in small to medium-sized tools. Thanks to the innovative ULTRA-FLO valve, it ensures an impressive flow rate of 1150 l/min at 6 bar with minimal pressure drop, while maintaining small external dimensions for easy integration. Its one-hand operation guarantees user comfort and speed, making it ideal for professional environments where efficiency matters. The body is manufactured from hardened QPQ-treated steel, providing exceptional resistance to wear and corrosion with a sleek black finish, while the connection part and sleeve are made of nickel-plated brass, and the spring, balls, and ring are crafted from stainless steel for long-lasting durability. Equipped with NBR sealing, the coupling delivers reliable performance across a wide temperature range from -20°C to +100°C and withstands working pressures up to 35 bar. This robust and versatile design ensures maximum safety, durability, and convenience, making it a trusted choice for demanding pneumatic applications. For optimal performance, couplings of series 1300 should not be combined with series 1300N.
