Is the GE-UN screw connection (carbon steel, zinc-nickel) compatible with hydraulic systems requiring a 4:1 safety factor and salt spray resistance up to 720 hours?

Yes. The GE-UN screw connection, carbon steel, zinc-nickel (24Â° DIN 2353 socket with external metric thread and external UNF thread, Oâring sealed) meets the stated requirements: - Safety factor: The GE-UN design is specified with a 4:1 safety factor, so it is suitable for hydraulic systems that require a 4:1 safety margin. - Corrosion resistance: The carbon steel components are coated with zincânickel (6â10 Âµm) and are described as providing very high corrosion resistance . specified performance up to 720 hours in a salt spray chamber . so they meet the salt spray resistance requirement. Additional notes to consider before final selection: confirm series selection (L light or S heavy) against your system pressure/axial load and verify compatibility of the Oâring material with your hydraulic fluid and operating temperature range.

Can the GE-UN screw connection, carbon steel, zinc-nickel, be used with metric and UNF thread adapters simultaneously?

Yes. the GE-UN screw connection, carbon steel, zinc-nickel can be used with metric and UNF thread adapters simultaneously, because the design of the GE-UN (24Â° DIN 2353 socket) provides an external metric thread and an external UNF thread on the same fitting, sealed with an Oâring. Key points to observe: - Dual-thread design: the GE-UN integrates both external metric and external UNF threads on the 24Â° DIN 2353 socket, allowing connection to adapters of either thread type. - Sealing: the UNF/metric interface is sealed with an Oâring, so correct Oâring installation and condition are essential for leak-free performance. - Strength and series: the connection meets DIN 2353 geometry with a safety factor of 4:1 and is available in L (light) and S (heavy) series. choose the series appropriate for the working pressure and mechanical loads. - Corrosion protection: the carbon steel body is zincânickel coated (6â10 Âµm) with very high corrosion resistance (up to 720 hours in salt spray), so it is suitable for demanding environments. - Installation notes: ensure compatible thread engagement, torque values, and use of the Oâring as specified by DIN 2353; do not mix incompatible adapter designs or damaged threads. When properly installed with the correct adapters and Oâring, the GE-UN screw connection, carbon steel, zinc-nickel permits the simultaneous use of metric and UNF threaded adapters as intended by its dual-thread configuration.
