Is the Walterscheidâ¢ GE-NT screw connection, carbon steel compatible with anaerobic thread sealants instead of Teflon tape for NPT/threaded sealing?

Yes. The Walterscheidâ¢ GE-NT screw connection, carbon steel (24Â° DIN 2353 socket with external metric thread and external NPT thread) is specified to seal on the thread "with Teflon tape or anaerobic sealant." That means anaerobic thread sealants are an acceptable alternative to PTFE (Teflon) tape for NPT/threaded sealing on this fitting. Practical notes and recommendations: - Use an anaerobic sealant rated for tapered NPT threads and compatible with steel and the fluids/system temperature and pressure. - Follow the sealant manufacturerâs cure time and application instructions; anaerobic sealants require metal-to-metal contact and absence of air to cure. - Apply correct torque per DIN 2353/Eaton Walterscheid guidance and observe the partâs specified safety factor (2.5:1). Over-tightening can damage threads or seating surfaces. - Ensure the Guardian Sealâ¢ galvanic coating and any system materials are chemically compatible with the chosen sealant. - For critical or high-pressure applications, validate the assembly with leak testing after installation. In short: yes.anaerobic thread sealant is compatible and expressly listed as an acceptable sealing method for Walterscheidâ¢ GE-NT screw connection, carbon steel.

Can the Walterscheidâ¢ GE-NT screw connection, carbon steel be used with NPT thread sealants rated for high-pressure hydraulic applications?

Yes. The Walterscheidâ¢ GE-NT screw connection, carbon steel (24Â° DIN 2353 socket with external metric thread and external NPT thread) is designed to seal on the thread and explicitly permits use of thread sealants such as Teflon tape or anaerobic sealant. Using NPT thread sealants rated for high-pressure hydraulic applications is acceptable provided the sealant is compatible with the system fluids, temperature range and the carbon steel/Guardian Sealâ¢ coating. Ensure the chosen sealant does not impair torque values or assembly tolerances and follow Eaton/Walterscheid installation torque and safety guidelines (safety factor 2.5:1). If in doubt for extreme pressures or critical systems, consult Eaton/Walterscheid technical support for confirmation.

Does the Walterscheidâ¢ GE-NT screw connection, carbon steel require specific Torque values when using Teflon or anaerobic sealants?

No. The Walterscheidâ¢ GE-NT screw connection, carbon steel does not require special or different torque values specifically because Teflon tape or an anaerobic sealant is used on the NPT/external thread. Torque guidelines remain those appropriate for the GE-NT connectionâs size, series (LL, L, S), thread type and material (carbon steel with Guardian Sealâ¢ coating) as specified by Eaton/Walterscheid or applicable DIN 2353 installation instructions. Use the manufacturerâs recommended assembly torque or torque table for the specific GE-NT size and series; apply Teflon or anaerobic sealant only to the thread per the supplierâs installation guidance. Do not over-torque to compensate for sealant. over-torquing can damage threads or seating surfaces and compromise the seal and safety factor (2.5:1). If in doubt, consult Eaton/Walterscheid technical data or contact their technical support for exact torque values for your specific connection size and application.
