1/2 inch x 3-1/2 inch Stainless Steel Nipple

1/2" x 3-1/2" 304 Stainless Steel Nipple – Industrial-Grade Threaded Pipe Fitting

This 1/2" x 3-1/2" stainless steel pipe nipple is fabricated from Type 304 stainless steel, offering superior corrosion resistance in potable water, chemical, and industrial systems. The nipple features NPT threads on both ends for direct integration into pipe runs, equipment connections, or manifold systems where threaded joints are specified.

Engineered for environments where durability and chemical resistance are critical, 304 stainless steel provides excellent strength and oxidation resistance, particularly in moist or mildly corrosive applications. Commonly used in food processing, potable water systems, compressed air lines, and mechanical piping networks.

Application Benefits

• ✅ Corrosion Resistance: Suitable for both interior and exterior use, including exposure to chlorinated water and non-aggressive chemicals.
• ✅ High Pressure Tolerance: Designed to perform in systems subject to thermal expansion and contraction cycles or fluctuating pressure loads.
• ✅ Precision Machined Threads: Conforms to ANSI B1.20.1 standards to ensure proper fitment with other NPT components.

Specifications

• Material: ASTM A312 compliant 304 stainless steel
• Nominal Size: 1/2" NPT
• Length: 3-1/2" overall
• Thread Type: NPT (National Pipe Thread) – tapered for sealing under torque
• Operating Range: Suitable for temperatures up to 1500°F and pressure ratings in accordance with ASME B31.3

Installation Guidelines

For proper sealing, apply a compatible thread sealant or PTFE tape to male threads. Hand tightening followed by wrench engagement (typically 2–3 turns) is recommended. Avoid over-tightening to prevent galling or thread damage. Always ensure alignment and support of connected assemblies to prevent joint stress.

Common Installations

This pipe nipple is frequently utilized in:

• • Commercial plumbing and mechanical systems
• • Chemical processing lines requiring sanitary-grade material
• • Industrial air and fluid transport applications
• • Stainless steel manifolds and pump discharge assemblies

Material Note

Type 304 stainless steel is an austenitic alloy containing chromium and nickel, offering balanced corrosion resistance and mechanical properties. It is non-magnetic in the annealed condition and performs reliably across a range of pH environments.
