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

1-1/4" x 2" Stainless Steel Threaded Nipple – Built for Industrial-Grade System Integrity

The 1-1/4" x 2" Stainless Steel Nipple is a precision-machined component engineered for use in pressurized piping systems where corrosion resistance and strength are critical. Constructed from high-quality stainless steel, this nipple offers threaded male connections on both ends, allowing for seamless integration into various piping assemblies including potable water, gas, and process fluid systems.

It is commonly used in commercial, industrial, and municipal installations requiring robust performance under pressure and exposure to harsh media or environmental conditions. The short length makes it ideal for tight clearances or when bridging minimal pipe gaps between fittings or valves.

Product Benefits

• Thread Standard: Tapered male NPT threads per ANSI/ASME B1.20.1 for secure, pressure-rated sealing
• Material: 304 or 316 stainless steel provides superior resistance to rust, pitting, and chemical attack
• Operating Pressure: Suitable for working pressures up to 150 psi in standard service conditions (verify per specific application)
• Machined Finish: Smooth thread and surface finish for reduced galling and enhanced connection reliability
• Versatile Application: Compatible with water, steam, air, oil, and many chemical solutions

Specifications

• Size: 1-1/4" nominal pipe size
• Length: 2 inches overall
• Ends: Male NPT x Male NPT
• Material Grade: 304 or 316 Stainless Steel (verify per product marking)
• Compliance: ASTM A312 / A733 (pipe and nipple standards)

Installation Considerations

Threaded stainless nipples should be installed with an appropriate sealant (such as PTFE tape or anaerobic pipe compound) to ensure leak prevention. Over-tightening should be avoided to prevent thread deformation. Always confirm material compatibility with service media and local code requirements before use.

Common Applications

• Potable water systems (hot and cold)
• High-purity process piping
• Commercial and institutional plumbing assemblies
• HVAC hydronic and glycol loops
• Industrial gas, air, or chemical lines

Industry Insight

Stainless steel nipples are a preferred option in systems where longevity, corrosion resistance, and minimal maintenance are required. Their use is common in healthcare facilities, food service, and critical mechanical infrastructure where inferior materials cannot meet performance demands.

For installations requiring a durable, code-compliant, and corrosion-resistant connection, the 1-1/4" x 2" Stainless Steel Nipple provides consistent, professional-grade reliability. Specify stainless steel when your project demands lasting performance in challenging service environments.
