Is the Quick-connection socket DN7.4 with valve, threaded, hardened steel, 1300 series compatible with 1300N series couplings?

No . Quick-connection socket DN7.4 with valve, threaded, hardened steel, 1300 series is not compatible with 1300N series couplings. The product description explicitly states couplings of series 1300 should not be combined with series 1300N.

Can the Quick-connection socket DN7.4 with valve, threaded, hardened steel, 1300 series be used with PTFE-sealed hoses or fittings?

Quick-connection socket DN7.4 with valve, threaded, hardened steel, 1300 series uses NBR seals. PTFE-sealed hoses or fittings are chemically compatible with many media, but the socketâs fixed sealing material is NBR, so replacing or mating PTFE seals will not change the socketâs built-in NBR seal. If you plan to connect PTFE-sealed components, ensure mechanical fit (BSP/BSPT thread type) and note potential sealing incompatibility: PTFE-to-NBR contact may leak if threads/seats rely on NBR deformation. For best results either use fittings designed for metal-to-metal or NBR sealing, or modify the socket by replacing seals with PTFE-compatible parts approved by the manufacturer. Do not mix 1300 with 1300N series.

Q: Can the Quick-connection socket DN7.4 with valve, threaded, hardened steel, 1300 series be used at pressures above 6 bar?

Yes. Quick-connection socket DN7.4 with valve, threaded, hardened steel, 1300 series has a rated working pressure of 35 bar, so it can technically be used at pressures above 6 bar. However, its performance specification (air flow 1150 l/min) is given at Pe = 6 bar with Îp = 0.5 bar; operation at higher pressures will change flow and Îp characteristics and may affect sealing, wear, and service life. Also ensure compatibility (do not combine series 1300 with 1300N), verify sealing material (NBR) and temperature limits (â20Â°C to +100Â°C) for your application, and follow applicable safety standards and installation instructions.

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

Universal quick coupling socket with valve DN7.4, with external BSPT thread or internal BSP thread. Designed primarily for compressed air and gases, for smaller and medium tools and pneumatic systems. Durable and easy to use, high flow rate with small external dimensions due to the use of ULTRA-FLO valve. Operated with one hand. The socket body is made of hardened steel through the process of carbonitriding in a salt bath QPQ, increasing resistance to wear and corrosion (black color). couplings of series 1300 should not be combined with series 1300N. Performance: 1150 l/min, Pe=6 bar, Δp=0.5 bar (air). Working pressure: 35 bar. Material: hardened QPQ steel (socket body), nickel-plated brass (connection part and sleeve), stainless steel (spring, balls, and ring). Sealing: NBR. Operating temperature: from -20°C to +100°C.
