Is the CEJN 115 Quick Connect Plug with Female Thread & Valve, Hardened Steel compatible with standard hydraulic couplings up to 1000 bar?

Yes. The CEJN 115 Quick Connect Plug with Female Thread & Valve, Hardened Steel is compatible with standard high-pressure hydraulic couplings and is specifically engineered for systems up to 1000 bar working pressure when connected. Constructed from hardened, galvanized steel with NBR sealing, it provides durable, leak-free performance and safety in extreme conditions. It features a nominal diameter of 2.5 mm, flow capacity of 6 l/min at Δp = 4 bar, a burst pressure of 2600 bar, and an operating temperature range of -30°C to +100°C, making it suitable for hydraulic presses, lifting devices, rescue tools and other high-pressure equipment.

Can the CEJN 115 Quick Connect Plug with Female Thread & Valve, Hardened Steel be used with NBR-sealed systems exposed to temperatures below -30°C without performance loss?

No. The CEJN 115 Quick Connect Plug with Female Thread & Valve, Hardened Steel is specified with NBR sealing and an operating temperature range of -30°C to +100°C. Use below -30°C risks NBR hardening, loss of elasticity and sealing performance, increased leak tendency and possible premature failure. For reliable operation below -30°C choose a coupling with low-temperature-rated seals (e.g., FKM/FFKM or specially formulated NBR for subzero use) or consult CEJN for a validated low-temperature variant.
