1/2 inch x 5-1/2 inch Stainless Steel Nipple

1/2" x 5-1/2" Stainless Steel Nipple – Threaded Schedule 40 Pipe Fitting

The 1/2" x 5-1/2" Stainless Steel Nipple is a precision-machined component used for extending or joining pipe runs in pressure systems. Fabricated from corrosion-resistant stainless steel, it provides durable performance in applications requiring strength, longevity, and chemical resistance. The nipple features National Pipe Thread (NPT) male threads on both ends and conforms to dimensional and material standards suitable for mechanical and plumbing system integration.

Material and Construction

Manufactured from stainless steel—commonly 304 or 316 grade—this fitting delivers enhanced resistance to oxidation, pitting, and corrosion, making it suitable for demanding indoor and outdoor applications. Threads are cut to ANSI/ASME B1.20.1 standard, allowing compatibility with a wide range of industrial and plumbing system components.

Key Specifications

• ✅ Nominal Size: 1/2" NPT x 5-1/2" length
• ✅ Material: Stainless Steel (typically ASTM A312, TP304 or TP316)
• ✅ Wall Thickness: Schedule 40 standard
• ✅ Connection Type: Male Threaded x Male Threaded (NPT)
• ✅ Pressure Rating: Suitable for use in ANSI-rated pipe systems (verify per application)

Field Application

This stainless steel nipple is suitable for potable water, chemical process piping, steam, compressed air, and natural gas systems. It is frequently specified for use in facilities where corrosion resistance is a priority, including food processing, marine, commercial HVAC, and industrial piping networks.

Installation Guidelines

Install using approved thread sealants or PTFE tape to achieve a leak-tight seal. Use appropriate wrenches on wrench flats or body to avoid thread deformation during tightening. Ensure proper alignment and thread engagement to meet pressure integrity requirements. Always follow applicable code requirements (e.g., IPC, UPC, ASME B31.1/B31.3).

Material Insight

Stainless steel provides a longer service life than galvanized or brass in corrosive environments and is non-reactive to most waterborne and chemical agents. For systems in aggressive environments or with exposure to chlorides, Type 316 stainless steel is preferred for added corrosion resistance.

The 1/2" x 5-1/2" Stainless Steel Nipple is engineered for reliable performance in demanding mechanical and plumbing applications. Its threaded design and corrosion-resistant material make it an essential component for professionals seeking durable, code-compliant piping solutions.
