Does the Walterscheidâ¢ GE-BT screw connection, carbon steel, require Teflon tape or anaerobic sealant for the BSPT external thread to ensure proper sealing?

Yes. The Walterscheidâ¢ GE-BT screw connection, carbon steel (DIN 2353 type GE-BT) requires sealing of the BSPT external thread. The product description specifies âseal on the thread â with Teflon tape or anaerobic sealant,â so you should apply either PTFE (Teflon) tape or an appropriate anaerobic thread sealant to the BSPT male thread to ensure proper, leak-tight sealing. Use the correct tape application (wrap direction and 2â3 turns) or a sealant rated for hydraulic/fluid service and compatible with carbon steel and the hydraulic fluid in use. Follow torque and assembly instructions from Walterscheidâ¢ to avoid over-tightening and to maintain the specified 2.5:1 safety factor.

Can the Walterscheidâ¢ GE-BT screw connection, carbon steel, be used with fluids under pressure without additional thread sealant on the BSPT external thread?

No. According to the DIN 2353 description for the Walterscheidâ¢ GE-BT screw connection, carbon steel, the BSPT external thread requires a thread sealant (e.g., Teflon tape or anaerobic sealant) for sealing. The GE-BT design seals on the 24Â° DIN 2353 socket, but the BSPT external thread is explicitly noted as âseal on the thread â with Teflon tape or anaerobic sealant,â so fluids under pressure should not be used without additional thread sealant.

Is thread locker acceptable instead of Teflon tape or anaerobic sealant for Walterscheidâ¢ GE-BT screw connection, carbon steel?

No. a general-purpose thread locker is not an acceptable substitute for the specified sealing methods for Walterscheidâ¢ GE-BT screw connection, carbon steel. Why: - The Walterscheidâ¢ GE-BT screw connection, carbon steel (24Â° DIN 2353 socket with external metric thread and BSPT external thread) explicitly specifies that the seal is achieved on the thread using Teflon tape or an anaerobic sealant. Those materials are chosen to provide a fluid-tight seal on tapered BSPT threads and to be compatible with hydraulic systems and service conditions. - Typical thread lockers (e.g., removable or permanent anaerobic threadlocking adhesives designed to prevent loosening) are formulated to lock threads mechanically, not to reliably seal pressurized fluid paths, especially on tapered pipe threads where sealing depends on thread surface fill and deformation. They may not fill thread imperfections or provide the same leakage resistance as PTFE tape or a dedicated anaerobic sealant rated for hydraulic sealing. - Compatibility and performance: PTFE tape and hydraulic-grade anaerobic sealants are selected for chemical compatibility with hydraulic fluids, temperature range, and pressure. Offâlabel thread lockers may degrade, become brittle, migrate into the hydraulic system, or fail under pressure/temperature cycling. - Safety and spec compliance: Using anything other than the manufacturer-specified sealing methods may void warranty, reduce the intended safety factor, and risk leaks or component failure. Walterscheidâ¢ GE-BT connections have a safety factor 2.5:1 and Guardian Sealâ¢ galvanic coating; maintaining specified assembly practice is essential. Recommendation: - Use Teflon (PTFE) tape or an appropriate hydraulic-grade anaerobic pipe sealant as specified by the manufacturer. - If you consider an anaerobic product that also functions as a threadlocker, confirm its technical data sheet explicitly states suitability for BSPT/tapered hydraulic thread sealing, compatibility with hydraulic fluids, pressure rating, and service temperature. Obtain written approval from the equipment manufacturer or supplier before substituting. - Do not rely on general-purpose thread lockers unless certified for pipe/tapered hydraulic thread sealing.
