1/2-Inch Male NPT to 3-Inch Threaded Brass End Schedule 80 Pipe Nipple

Description

Description
A reliable, high-quality red brass pipe nipple built for robust plumbing and industrial applications. Ideal for joining two female threaded fittings in systems handling air, gas, oil, water, or steam — this nipple combines durability with compatibility.

Key Specifications

• Material: Red Brass (ASTM B43)
• Schedule: Schedule 80 (heavier wall)
• Outside Diameter: 27/32″
• Wall Thickness: 0.149″
• Application / Fluid Compatibility: Suitable for air, natural gas, oil, potable water, steam
• Operating Temperature Range: –20 °F to 400 °F
• Maximum Pressure (Steam): 267 psi @ 450 °F
• Country of Origin: Mexico

Benefits & Use Cases

• Stronger Wall Construction: Being Schedule 80, this nipple offers greater strength and durability, especially in higher-pressure or more demanding systems compared to standard Schedule 40.
• Threaded Connections on Both Ends: The MNPT threading allows for direct connection to female NPT fittings, simplifying system layout and reducing additional coupling parts.
• Corrosion Resistance: Red brass metal offers good resistance in plumbing and industrial environments, making it ideal for water, oil, and gas systems.
• Versatile Applications: Useful in plumbing, heating, steam, and fluid transfer systems where a durable, short connector is needed.
• Temperature & Pressure Rated: Can withstand elevated temperatures and pressures in many industrial piping setups.

Installation & Usage Tips

1. Use Correct Thread Sealant: Apply PTFE (Teflon) tape or pipe dope to the MNPT threads for a reliable, leak-free seal.
2. Do Not Over-Tighten: Over-tightening can damage threads or distort the nipple; hand-tight plus a fraction of a turn with a wrench is enough.
3. Support Nearby Components: Use proper pipe supports or clamps to avoid stress on the nipple due to vibrations or weight on connected piping.
4. Inspect for Leaks: After pressurizing, check joints with soapy water or leak detection methods, especially for steam or gas service.
5. Replace if Deformed or Corroded: Since this is a small but critical connector, swap it out if you detect wear, corrosion, or thread damage.
