Thread & Standard Explanation
This NPT male elbow is manufactured with ANSI / ASME B1.20.1 compliant NPT threads, which are widely used in hydraulic, pneumatic, and industrial piping systems. The tapered thread structure allows the fitting to form a tight seal through thread interference.
- Thread Type: NPT (National Pipe Taper) male thread
- Thread Standard: ANSI / ASME B1.20.1
- Sealing Method: Tapered thread sealing with PTFE tape or thread sealant
Compared with parallel threads, NPT male threads provide better sealing performance under pressure, making this elbow fitting suitable for high-pressure hydraulic applications. The 90° elbow design also helps optimize piping layouts where space is limited.
This adapter is designed to connect metric tube fittings to NPT female ports, allowing easy integration between metric hydraulic components and NPT-based systems.
