Is the GE-MB screw connection, carbon steel compatible with hydraulic systems requiring a 2.5:1 safety factor?

Yes. The GE-MB screw connection, carbon steel (24Â° DIN 2353 socket with external metric thread and external metric thread, sealing DIN 3852 type B â metal to metal) is specified with a safety factor of 2.5:1 and is therefore compatible with hydraulic systems that require a 2.5:1 safety factor. It is offered in L (light) and S (heavy) series and is made of galvanized carbon steel, matching the stated requirement.

Can GE-MB screw connection, carbon steel be used with non-lubricated fluids or does it require lubrication for reliable sealing?

The GE-MB screw connection, carbon steel (24Â° DIN 2353, metal-to-metal sealing DIN 3852 type B) is designed for metal-to-metal sealing and typically requires lubrication or assembly paste on sealing surfaces and threads to ensure reliable sealing and avoid galling, especially with carbon steel and galvanized surfaces. With non-lubricated fluids alone, reliable long-term sealing is not guaranteed because lack of lubrication increases risk of metal wear, fretting and micro-leakage. For dependable performance follow manufacturer torque, surface condition and use appropriate assembly lubrication; otherwise use connections/seat designs specifically qualified for dry assembly.

Does GE-MB screw connection, carbon steel require specific torque values for proper sealing and safety?

Yes. The GE-MB screw connection, carbon steel requires specified tightening to achieve reliable metal-to-metal sealing and maintain the stated safety factor. Key points: - Sealing type: metal-to-metal (DIN 3852 type B) with a 24Â° DIN 2353 socket. Metal-to-metal seals depend on correct axial compression and mating-face contact, which are achieved by proper torque. - Threaded interface: external metric threads on the fitting must be tightened so the sealing face seats fully against the counterpart; underâtightening risks leaks, overâtightening can deform threads or sealing faces and reduce safety. - Safety factor: the assembly is specified with a 2.5:1 safety factor. Maintaining that factor in service assumes correct assembly torque and avoidance of thread damage or overstress during tightening. - Series and material: both L (light) and S (heavy) series in carbon steel (galvanized) will have different recommended torque values due to geometry and material thickness; follow seriesâspecific torque or installation tables. - Practical guidance: use the manufacturerâs or DIN 2353 installation torque/assembly table for the specific size and series. If such tables are unavailable, use calibrated torque or hydraulic spanners and inspect sealing faces for proper contact and absence of damage. Apply lubrication only where recommended to avoid altering torque-to-preload relationship. Conclusion: Specific torque values are required; always use the manufacturerâs or DINâspecified torque/assembly data for the particular GE-MB size and series to ensure proper sealing and preserve the 2.5:1 safety factor.
