Is the GE-MT screw connection, carbon steel (24Â° DIN 2353, seal on thread) rated with a safety factor of 2.5:1 for both L and S series?

Yes. The GE-MT screw connection, carbon steel (24Â° DIN 2353, seal on thread) is rated with a safety factor of 2.5:1 for both L (light) and S (heavy) series. The DIN 2353 description specifies the safety factor 2.5:1 and lists availability in both L and S series, material carbon steel, galvanized, with seal on the thread (Teflon tape or anaerobic sealant).

Are installation threads on the GE-MT screw connection, carbon steel sealed on thread, compatible with Teflon tape or anaerobic sealant for L and S series?

Yes. GE-MT screw connection, carbon steel (seal on the thread) is compatible with PTFE (Teflon) tape or anaerobic sealant for both L (light) and S (heavy) series. Per DIN 2353 the GE-MT type uses a 24Â° socket with external metric thread and an external metric tapered thread designed for thread sealing (seal on the thread). Use appropriate amount of PTFE tape or a recommended anaerobic sealant compatible with carbon steel and hydraulic fluids, and follow manufacturer torque and assembly instructions to preserve the 24Â° sealing face and required safety factor (2.5:1).

Can the GE-MT screw connection, carbon steel (24Â° DIN 2353, thread-sealed) be used in hydraulic systems with working temperatures above 120Â°C?

No. The GE-MT screw connection, carbon steel (24Â° DIN 2353, thread-sealed) is not suitable for continuous hydraulic service above 120Â°C. Reasons: - Thread seal method: The description specifies sealing on the thread using PTFE (Teflon) tape or anaerobic sealant. Standard PTFE tape and common anaerobic sealants have temperature limits at or below ~120â200Â°C depending on formulation; prolonged exposure above 120Â°C can degrade sealant properties, causing leaks. Thread-seal reliability at elevated temperatures is therefore uncertain unless a high-temperature-rated sealant specifically certified for the application is used. - Material and coating: Carbon steel (galvanized) itself may withstand higher temperatures, but the zinc galvanization can degrade and lose protective properties at elevated temperatures, risking corrosion and hydrogen embrittlement in service conditions. - Design & safety factor: The component is designed per DIN 2353 with a safety factor of 2.5:1 and offered in light (L) and heavy (S) series, but DIN 2353 fittings with thread sealing are typically specified for hydraulic fluids and temperatures within standard hydraulic ranges (commonly up to ~120Â°C). Exceeding manufacturerâs specified temperature range can affect mechanical integrity, sealing performance, and safety margin. Recommendation: Consult the manufacturerâs technical data sheet and temperature ratings for the specific GE-MT product and the sealant used. For reliable operation above 120Â°C, consider fittings and sealing methods explicitly rated for high-temperature hydraulic service (e.g., metal-to-metal seals, high-temp sealants certified for the temperature, or fittings made from materials/coatings specified for elevated temperatures).
