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

1" x 4-1/2" Stainless Steel Nipple – Precision-Crafted for Industrial and Commercial Use

The 1" x 4-1/2" stainless steel nipple is engineered for high-performance fluid handling across commercial, industrial, and process piping systems. Manufactured from corrosion-resistant stainless steel, this fitting is ideal for connecting threaded pipe sections in applications that demand strength, hygiene, and long service life.

Product Advantages

• Material Composition: Constructed from 304 stainless steel, providing excellent resistance to oxidation, scaling, and chemical degradation in potable and non-potable systems.
• Thread Accuracy: Machined NPT (National Pipe Taper) threads ensure precise engagement, supporting tight, leak-resistant joints with compatible components.
• Working Pressure Rating: Suitable for systems operating under moderate to high pressure, depending on application, pipe schedule, and installation method.
• Hygienic Properties: Stainless steel surfaces are non-porous and easy to sanitize, making this fitting appropriate for systems where cleanliness is essential.
• Mechanical Durability: Withstands mechanical impact, vibration, and thermal cycling, maintaining structural integrity over long-term service.

Technical Specifications

• Nominal Size: 1 inch
• Overall Length: 4-1/2 inches
• Material Grade: 304 Stainless Steel (ASTM A312 or equivalent)
• Thread Type: NPT Male x NPT Male
• Compliance: Meets ASME B1.20.1 and ASTM standards for metallic pipe fittings

Installation Notes

• Apply an approved thread sealant (PTFE tape or pipe dope) to male threads to achieve leak-tight connections.
• Use pipe wrenches or strap wrenches to secure the nipple without distorting threads or damaging surface finish.
• Ensure compatibility with system pressure ratings and fluid media prior to installation.

Common Applications

This stainless steel nipple is widely used in mechanical piping systems, including potable water distribution, chemical process lines, compressed air systems, and HVAC equipment connections. Its durability and corrosion resistance make it suitable for demanding indoor and outdoor installations.

Did You Know?

304 stainless steel offers a combination of chromium and nickel content that makes it highly resistant to atmospheric and aqueous corrosion—ideal for fittings used in both urban infrastructure and industrial facilities.

For robust, code-compliant installations that require clean, corrosion-resistant, and mechanically strong connections, the 1" x 4-1/2" stainless steel nipple delivers the reliability professionals demand.
