1 inch x 5-1/2 inch Stainless Steel Nipple

1" x 5-1/2" 304 Stainless Steel Nipple – Built for High-Demand Piping Systems

The 1" x 5-1/2" 304 Stainless Steel Nipple is manufactured for durability and precision in piping installations where strength, corrosion resistance, and leak prevention are critical. Engineered from 304 stainless steel, this nipple is suitable for high-pressure systems and corrosive environments commonly encountered in commercial, industrial, and mechanical piping.

Performance Characteristics

• ✅ Corrosion Resistance – 304 stainless steel offers excellent resistance to oxidizing agents, chlorides, and other corrosive elements.
• ✅ Thread Integrity – NPT (National Pipe Thread) ends are machined for a tight, secure fit, reducing the risk of thread galling and system leaks.
• ✅ High-Pressure Capability – Suitable for systems with moderate to high working pressure, depending on the connected piping and media.
• ✅ Thermal Stability – Maintains structural reliability in applications with wide temperature variations.

Technical Specifications

• Size: 1" nominal diameter x 5-1/2" length
• Material: ASTM A312-compliant 304 stainless steel
• Connection: Male threaded (NPT both ends)
• Finish: Pickled or passivated to maintain corrosion resistance

Common Applications

This nipple is routinely used in process piping, chemical conveyance systems, potable water distribution, and mechanical connections in heating and cooling systems. Its corrosion-resistant build also makes it suitable for food-grade and sanitary applications where material integrity is a priority.

Installation Guidelines

Use thread sealant or PTFE tape to achieve a proper seal during installation. Over-tightening should be avoided to maintain thread integrity. For critical or hazardous systems, hydrostatic pressure testing is recommended following installation.

Did You Know?

304 stainless steel is composed of 18% chromium and 8% nickel, offering a balance of strength and resistance to various corrosive agents—making it one of the most commonly used stainless alloys in piping systems.

For professional-grade performance and compliance with industry best practices, choose the 1" x 5-1/2" 304 Stainless Steel Nipple when reliability, longevity, and corrosion resistance are essential to your job.
