Can the DN7.4 Quick-Connect Socket with Valve, Threaded Hardened Steel, 1300 Series be safely used with other coupling series (e.g., 1300N)?

DN7.4 Quick-Connect Socket with Valve, Threaded Hardened Steel, 1300 Series Format: No — for optimal performance and safety, couplings of series 1300 should not be combined with series 1300N. The product description explicitly advises against mixing these series; use matching series components to ensure proper sealing, valve operation, pressure handling (up to 35 bar), and durability.

Is the DN7.4 Quick-Connect Socket with Valve, Threaded Hardened Steel, 1300 Series compatible with couplings from other manufacturers or different pressure ratings?

DN7.4 Quick-Connect Socket with Valve, Threaded Hardened Steel, 1300 Series Format is designed for broad compatibility within pneumatic systems but has important limits. It will generally mate with couplings that follow the same 1300 series dimensional and sealing standards and can operate safely with other manufacturers’ couplings if those parts match the 1300 series specifications (thread, diameter, valve interface and NBR sealing compatibility). Performance-wise it tolerates working pressures up to 35 bar and delivers high flow (1150 l/min at 6 bar), so mixing with couplings rated for equal or higher pressures is acceptable; however, pairing with lower-rated couplings may create a safety risk. Critically: do not combine couplings of series 1300 with series 1300N. If in doubt, verify the other manufacturer’s part numbers, series designation, pressure rating and sealing material to ensure mechanical fit and pressure/temperature compatibility before use.

Additional information

Material	CS – steel (cast iron)
Standard length [m]	120

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.
