1/4 inch x 4 inch Stainless Steel Nipple

1/4" x 4" Stainless Steel Nipple – 304 Grade for Industrial-Grade Threaded Connections

This 1/4" x 4" Stainless Steel Nipple is fabricated from ASTM A312-compliant 304 stainless steel, offering reliable performance in fluid, air, and gas transfer systems. It features precision-machined NPT threads at both ends for joining two threaded components in corrosive or high-temperature environments.

Manufactured for use in applications where chemical resistance and mechanical integrity are critical, this Schedule 40 nipple is suitable for potable water systems, compressed air lines, instrumentation loops, and process piping. The 304 alloy composition provides excellent resistance to oxidation and pitting in a variety of environments, including mildly acidic or alkaline conditions.

Key Performance Characteristics

• ✅ 304 Stainless Steel Construction – Provides superior resistance to corrosion, ideal for chemical, water, and industrial environments.
• ✅ Accurate NPT Threading – Conforms to ANSI B1.20.1 for compatibility with standard fittings and valves.
• ✅ Schedule 40 Wall Thickness – Delivers mechanical strength for both moderate and high-pressure applications.
• ✅ Temperature Stability – Maintains strength and dimensional stability in elevated temperature service up to 1500°F (816°C).

Applications

Commonly used in the following systems:

• Process and instrumentation piping
• Water purification and distribution systems
• Food-grade and pharmaceutical manufacturing facilities (verify 3A/NSF compliance if required)
• Corrosive service in petrochemical and marine applications

Installation Considerations

This component should be installed using appropriate sealing methods, such as PTFE thread seal tape or anaerobic thread compound, to achieve leak-free operation. Over-torquing should be avoided to prevent thread galling or joint misalignment. When used in systems with aggressive media, verify material compatibility with process fluids prior to installation.
