Stainless Steel Female Connector – 3/4" Tube OD x 1/2" FNPT | Compression x NPT

This 3/4″ tube OD x 1/2″ female NPT fitting is engineered for secure, high-pressure transitions between compression-style tubing connections and threaded process ports. Built from 316 stainless steel, it combines long-term corrosion resistance with the mechanical strength needed for demanding service conditions in sanitary and industrial fluid systems. Precision-machined compression ends deliver clean, repeatable sealing on stainless tubing, while the tapered NPT threads ensure a leak-tight, vibration-resistant engagement in pressure-rated assemblies.

By bridging tubing and threaded ports, this fitting supports efficient system layouts across a wide range of applications. It is frequently deployed in Clean-in-Place (CIP) skids, fuel delivery systems, analyzer panels, and process control setups where reliable performance is non-negotiable. The tapered threading is cut to ANSI B1.20.1 standards, providing compatibility with instrumentation-grade components and Swagelok® style assemblies for consistent, cross-brand integration.

Its robust design makes it ideal for installations where connections are exposed to cycling pressures, thermal swings, and high levels of vibration. By maintaining sealing performance without the need for additional sealants on the compression side, it supports clean, low-maintenance service in hygienic and high-purity environments. Whether incorporated into new system builds or used as part of a retrofit project, this connector offers engineers confidence in both performance and long-term durability.
