What is the stainless steel close nipple S3326 ?
The stainless steel close nipple S3326 is a compact, high-performance, fully threaded proximity fitting designed for demanding industrial fluid systems. It utilizes standardized metric NPT tapered threads, offering a self-tightening seal. This ensures a tight fit between the metal ends during connection, effectively preventing gas or liquid leakage without the need for additional sealing materials. Compared to traditional straight threads, the tapered threads create a wedge-shaped lock when tightened, enhancing connection strength and significantly improving sealing performance. This ensures reliable operation even under complex operating conditions such as high pressure, high temperature, and frequent vibration.
Made of high-quality stainless steel, the stainless steel close nipple S3326 offers excellent corrosion and oxidation resistance, making it suitable for use with corrosive fluids and harsh environments, while also withstanding significant temperature fluctuations and pressure shocks. Whether used in lubricating oil systems, refrigerant circuits, or precision hydraulic systems, the S3326 series demonstrates excellent compatibility and stability, making it an ideal choice for fluid connection solutions in modern industry.

Why does the S3326 proximity connector excel in industrial applications?
In applications such as lubricating oil transfer, refrigerant fluid control, and precision hydraulic circuits, sealing stability is a critical performance indicator. The S3326 series' male NPT thread design automatically locks into a tapered seal upon tightening, effectively preventing liquid or gas leakage. Furthermore, its high-temperature resistance and stainless steel construction ensure long-term performance stability in harsh environments.
Tapered Thread Self-Locking Seal, Eliminating Leakage Risks:The S3326 series utilizes a male NPT (National Pipe Taper) tapered thread design, which is inherently self-locking. When the connector is tightened, the threads compress, creating a tight fit and a reliable metal-to-metal sealing barrier. Compared to traditional straight thread fittings, it more effectively prevents leakage of high-pressure fluids or gases, making it particularly suitable for demanding applications such as lubricant delivery, refrigerant control, and hydraulic systems.
High-temperature and corrosion-resistant, adaptable to complex operating conditions:The S3326 is made of high-quality stainless steel (such as 304 or 316) with excellent corrosion resistance, capable of withstanding the corrosive challenges posed by most industrial fluids (such as lubricants, hydraulic fluids, refrigerants, and chemical solutions). Furthermore, this material exhibits excellent high-temperature resistance, minimizing deformation and maintaining a stable connection even in long-term, high-temperature operating environments.
High mechanical strength and shock and vibration resistance:The S3326 fitting offers exceptional mechanical strength, maintaining a seal without deformation despite high-velocity fluid impact, frequent vibration, and external loads. This makes it ideal for high-pressure pipe connections and applications requiring frequent replacement. 4. Wide Applicability and Industry Compatibility
Due to its standard NPT thread specifications, the S3326 proximity connector is easily compatible with a wide range of American standard industrial equipment and piping systems. It is widely used in industrial lubrication systems, refrigeration and freezing systems, high-precision hydraulic equipment, industrial pneumatic and vacuum systems, and the petrochemical and energy industries.
Easy Maintenance and Long Service Life:Thanks to its high-quality construction and materials, the S3326 connector boasts a long service life, significantly reducing maintenance downtime due to connector aging or failure. Furthermore, its threaded connection allows for easy installation and disassembly, facilitating system modifications and upgrades.
