Can the DN7.4 Eurostandard Quick-Connect Socket with Valve, Hose Fitting, Nickel-Plated Brass, 26KE Series be used at temperatures below -20°C without performance loss?

DN7.4 Eurostandard Quick-Connect Socket with Valve, Hose Fitting, Nickel-Plated Brass, 26KE Series is specified for an operating temperature range of -20°C to +60°C. Using it below -20°C would fall outside the manufacturer’s rated conditions and may lead to performance degradation (sealing hardening or leakage, reduced elasticity of NBR seals, altered spring behavior, brittleness of some components) and potential safety or durability issues. Therefore it should not be used below -20°C if you require guaranteed performance and compliance with the specified characteristics. If lower-temperature operation is necessary, consult the manufacturer for low-temperature variants or alternative materials (e.g., FKM/EPDM seals, specially treated springs) certified for colder service.

Additional information

Material	CS – steel (cast iron)

The quick coupling socket with Eurostandard DN7.4 profile and integrated valve is a reliable solution for safe and efficient air connections. Equipped with a hose fitting, it ensures secure, non-pressurized disconnection in full compliance with ISO 4414 and EN 983 standards, guaranteeing both safety and durability. Designed to work exclusively with hardened steel Rectus plugs type 25KA, it delivers optimal performance of 1300 l/min at 6 bar with a pressure drop of just 0.5 bar, while withstanding a maximum working pressure of 12 bar. The robust construction combines nickel-plated brass for the body and threaded parts, brass for the valve, AISI 301 steel for the spring, and hardened AISI 420 steel for pins and locking elements, complemented by NBR sealing for reliable tightness. With an operating temperature range from -20°C to +60°C, this coupling socket is engineered for demanding industrial environments, offering long-lasting performance and consistent reliability in compressed air systems.
