1/2 inch x 4 inch Stainless Steel Nipple

304 Stainless Steel Nipple – 1/2" x 4" Threaded Schedule 40

The 1/2" x 4" stainless steel nipple is fabricated from 304-grade stainless steel and designed for threaded pipe systems requiring corrosion resistance and mechanical strength. This schedule 40 welded nipple is manufactured to ANSI/ASME B1.20.1 specifications and delivers consistent performance in a range of industrial and commercial environments.

Engineered for durability and dimensional precision, this fitting is suitable for process piping, chemical handling, potable water systems, and general plumbing use. Its seamless threading allows for secure integration with compatible metal pipe and fittings, reducing the risk of system leaks under pressure or temperature variation.

Product Highlights

• ✅ Material: 304 Stainless Steel – Non-magnetic, corrosion-resistant alloy suitable for water, air, and chemical use
• ✅ Thread Type: NPT (National Pipe Thread) – ANSI/ASME B1.20.1 compliant
• ✅ Wall Thickness: Schedule 40 – Designed for moderate pressure applications
• ✅ Surface Finish: Uncoated, smooth steel for clean installations
• ✅ Pressure Rating: Varies with system design; compatible with ANSI-rated piping systems

Installation Considerations

Install using standard threading tools and sealants such as PTFE tape or anaerobic pipe dope. Apply uniform torque to avoid cross-threading or over-compression. For critical applications, verify system pressure ratings and compatibility prior to commissioning.

Common Applications

• • Potable and non-potable water lines
• • Compressed air systems
• • Mild chemical transport
• • Fire protection systems (non-UL/FM environments)
• • Mechanical and HVAC equipment connections

Compliance & Standards

• • Meets ASTM A312 and A733 for pipe and nipple manufacturing
• • Threads conform to ASME B1.20.1
• • Lead-free material suitable for use in systems governed by NSF/ANSI 372

Note:

Not intended for use in underground or marine applications without additional corrosion protection. For critical process systems, verify media compatibility with 304-grade stainless steel.
