1/2 inch x 6 inch Stainless Steel Nipple

304 Stainless Steel Nipple 1/2" x 6" – Industrial-Grade Threaded Pipe Fitting

The 304 Stainless Steel Nipple 1/2" x 6" is a precision-machined fitting used for joining sections of threaded pipe in pressurized fluid or gas systems. Fabricated from austenitic stainless steel conforming to ASTM A312 or A733 standards, this component offers excellent resistance to oxidation and corrosive environments.

Suitable for both potable water and non-potable industrial applications, this nipple is designed for use in systems requiring durability, chemical compatibility, and leak-resistant threaded connections. Its uniform wall thickness and clean threading ensure reliable joint integrity under pressure.

Performance Characteristics

• Material: 304 stainless steel (UNS S30400), offering high resistance to corrosion, scaling, and thermal fatigue
• Length: 6 inches overall, with fully threaded ends (close pattern) for compatibility with ANSI B1.20.1 pipe threads
• Nominal Pipe Size: 1/2 inch Schedule 40 (standard wall)
• Thread Type: Male National Pipe Thread (NPT), tapered for pressure-tight joints with appropriate sealant
• Temperature Rating: Suitable for service from -20°F to 1500°F depending on application and sealing method
• Pressure Rating: Dependent on system configuration, typically up to 150 PSI for water and 300 PSI for air/gas at ambient temperature

Typical Applications

• • Potable water distribution in corrosive or coastal environments
• • Food and beverage processing lines requiring hygienic components
• • Low- and high-pressure steam systems (when used within temperature ratings)
• • Chemical handling systems involving non-reactive or mildly corrosive media
• • Mechanical equipment assemblies and compressed air systems

Installation Guidance

Apply PTFE tape or thread sealant rated for stainless steel to ensure a secure seal. Avoid over-torque to prevent galling or thread distortion. When used in high-vibration or thermal cycling systems, verify torque retention post-installation.

Compliance & Standards

This product complies with lead-free plumbing requirements under NSF/ANSI 61 and NSF 372 when applicable. Manufactured to meet or exceed ASTM A733 for pipe nipples and ASTM A312 for stainless steel pressure pipe.

The 1/2" x 6" 304 Stainless Steel Nipple is a robust and versatile component designed to meet the stringent demands of commercial and industrial fluid handling systems. Its corrosion-resistant construction and precision threading make it a dependable choice for long-term performance in diverse environments.
