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

3/4" x 1-1/2" Stainless Steel Nipple – 304 Alloy, NPT Threaded Pipe Connector

The 3/4" x 1-1/2" Stainless Steel Nipple is a precision-machined Schedule 40 pipe segment constructed from Type 304 stainless steel. It features male National Pipe Thread (NPT) ends on both sides and is used to connect threaded fittings or components in systems requiring corrosion resistance and mechanical integrity.

Suitable for a wide range of process, mechanical, and plumbing systems, this nipple is designed for moderate- to high-pressure service in environments where temperature, moisture, or chemical exposure may affect standard steel components. Its short length and compact profile make it ideal for confined installations or connections between valves, tees, and instrumentation.

Product Features

• ✅ Material: Type 304 stainless steel conforming to ASTM A312/A733
• ✅ Nominal Size: 3/4 inch x 1-1/2 inch
• ✅ Thread Type: NPT x NPT, per ANSI/ASME B1.20.1
• ✅ Corrosion Resistance: Suitable for water, air, oil, steam, and non-aggressive chemical applications
• ✅ Temperature Range: Serviceable in temperatures up to 1500°F depending on pressure and sealant

Installation Guidelines

Threaded stainless steel nipples should be installed with compatible PTFE tape or thread sealant suitable for the system medium. Avoid excessive torque to maintain thread form and sealing surface. For use in potable water systems, confirm local code compliance and ensure sealant materials meet NSF/ANSI 61 requirements if applicable.

Typical Applications

• Potable and non-potable water systems
• Industrial process piping
• Steam, gas, and air distribution networks
• Corrosive environment utility piping
• Mechanical equipment and valve assemblies

Technical Note

Type 304 stainless steel offers a balance of corrosion resistance, mechanical strength, and weldability. Though not suitable for chloride-heavy environments (where Type 316 may be preferred), 304 performs reliably in most general-purpose applications, including indoor and light industrial settings.

The 3/4" x 1-1/2" Stainless Steel Nipple (Type 304) is designed for high-integrity threaded connections in environments where reliability and corrosion resistance are required. Engineered for performance in commercial, industrial, and mechanical piping systems.
