Is the GE-NT Screw Connector, Carbon Steel compatible with both metric and NPT threaded ports without adapters?

Yes. The GE-NT Screw Connector, Carbon Steel is designed with both external metric and external NPT threads, so it can be installed into either metric or NPT threaded ports without the need for adapters. It provides a secure thread seal that can be reinforced with Teflon tape or anaerobic sealant to ensure leak-free performance across hydraulic and pneumatic systems.

Can the GE-NT Screw Connector, Carbon Steel be used with anaerobic sealants instead of Teflon tape without compromising the 24° socket fitting seal?

Short answer: Yes — the GE-NT Screw Connector, Carbon Steel can be used with anaerobic sealants instead of Teflon tape without compromising the 24° socket fitting seal, provided proper application and cure time. Why: The product description explicitly states the secure thread seal can be reinforced with Teflon tape or anaerobic sealant, and the 24° socket seal is a mechanical metal-to-metal sealing surface independent of the thread seal. Anaerobic sealants fill thread voids and prevent leakage along threads; they do not alter the 24° cone contact when fittings are assembled correctly. Key application notes: - Clean threads and mating surfaces of oil, dirt, and old sealant before applying anaerobic adhesive. - Apply the anaerobic sealant per manufacturer instructions (amount, cure time, temperature). - Assemble to recommended torque to ensure proper 24° contact — over- or under-tightening can affect the cone seal. - Use sealants compatible with carbon steel and intended media (hydraulic fluids, etc.). - For critical or high-pressure services, allow full cure and consider pressure testing after assembly. Conclusion: When installed and torqued correctly with a compatible anaerobic sealant and proper surface preparation, the GE-NT Screw Connector, Carbon Steel will maintain its 24° socket fitting seal and provide reliable, leak-free performance.
