3/4 inch x 3-1/2 inch Stainless Steel Nipple

3/4" x 3-1/2" Stainless Steel Pipe Nipple – Threaded Connector for Corrosion-Resistant Systems

The 3/4" x 3-1/2" Stainless Steel Nipple is a Schedule 40 pipe fitting with male National Pipe Thread (NPT) ends on both sides, designed to extend pipe runs or connect fittings in high-demand fluid handling systems. Made from corrosion-resistant stainless steel, this nipple is suitable for use in potable water, chemical, and industrial applications where material integrity and long service life are essential.

It is manufactured to precise dimensional tolerances and pressure ratings consistent with ASME B1.20.1 thread standards and ASTM A312 or A733 material specifications, depending on manufacturer. The 3-1/2" length provides a compact solution for tight installations or short span connections.

Product Features

• ✅ Material: Stainless Steel, typically Type 304 or 316 for superior corrosion resistance
• ✅ Full NPT Threads: Machined to ANSI/ASME B1.20.1 for leak-resistant, tapered engagement with compatible fittings
• ✅ Schedule 40 Wall Thickness: Suitable for moderate pressure and temperature service in industrial and potable water systems
• ✅ Non-Galvanic Performance: Ideal for systems where contact with dissimilar metals must be minimized to reduce electrochemical reaction

Technical Specifications

• Nominal Size: 3/4 inch
• Length: 3-1/2 inches (overall including threaded ends)
• Connection Type: NPT Male x NPT Male
• Standard Compliance: ASTM A733 / A312, ANSI/ASME B1.20.1

Installation Guidelines

Use thread sealant or PTFE tape appropriate for the system medium (e.g., water, air, steam, or corrosive fluids). Align fittings carefully to prevent cross-threading and apply proper torque to avoid damage to threads. Stainless steel threads may require anti-galling lubricant in some applications.

Common Applications

Installed in potable water lines, food-grade processing systems, hydronic piping, industrial fluid transfer systems, and environments exposed to chemical agents or high moisture. Also applicable in marine, laboratory, and pharmaceutical installations requiring non-reactive, corrosion-resistant materials.

Code & Safety Note

Stainless steel fittings meet NSF/ANSI 61 when specified and are often approved for use in drinking water systems. Confirm compatibility with system materials and local jurisdictional codes during design and installation.

The 3/4" x 3-1/2" Stainless Steel Pipe Nipple provides a dependable, corrosion-resistant threaded connection for use in high-performance systems requiring long-term reliability and dimensional precision.
