3/4 inch x 6 inch Stainless Steel Nipple

3/4" x 6" Stainless Steel Nipple – Threaded Fitting for Corrosion-Resistant Pipe Connections

The 3/4" x 6" Stainless Steel Nipple is a precision-machined pipe fitting designed for threaded piping systems in commercial, industrial, and residential applications. Fabricated from 304 stainless steel, this nipple offers excellent mechanical strength and corrosion resistance for use in potable water, chemical transport, and pressurized systems.

Application and Performance Benefits

• ✅ Corrosion Resistance – Constructed from austenitic stainless steel (typically 304 grade) for superior resistance to rust and oxidation, especially in high-humidity or chemically active environments.
• ✅ Threaded Male Ends – NPT (National Pipe Taper) threads on both ends ensure compatibility with standard threaded pipe fittings and allow for a tight mechanical seal using thread compound or PTFE tape.
• ✅ Seamless or Welded – Available in both seamless and welded configurations, depending on manufacturer specifications and intended pressure ratings.
• ✅ Extended Length for Layout Flexibility – 6-inch length accommodates spacing or connection requirements in line extensions or system modifications.

Technical Specifications

• Nominal Pipe Size: 3/4 inch
• Length: 6 inches
• Material: 304 Stainless Steel (ASTM A312 or A733)
• Connection Type: Male NPT x Male NPT
• Pressure Rating: Dependent on wall thickness; suitable for low- to medium-pressure service
• Temperature Range: Typically rated for up to 1500°F (816°C), depending on service conditions
• Compliance: Meets NSF/ANSI standards where applicable for potable water use

Installation Guidance

Threaded pipe nipples must be installed using appropriate sealing materials, such as anaerobic pipe sealant or PTFE tape. Apply sealant evenly to male threads and tighten using standard pipe wrenches to the recommended torque specification. Over-tightening can result in thread distortion or fitting failure.

Common Use Cases

This fitting is commonly used in the following systems:

• Potable and non-potable water lines
• Hydronic heating systems
• Compressed air systems
• Process piping in commercial kitchens, labs, and clean environments
• Corrosive or high-humidity mechanical rooms

Note for Code Compliance

Ensure that the use of stainless steel nipples meets applicable local plumbing and mechanical codes, especially when transitioning between dissimilar metals (e.g., galvanized to stainless) to prevent galvanic corrosion. Dielectric unions may be required in certain installations.

The 3/4" x 6" Stainless Steel Nipple provides a high-integrity threaded solution for installations where corrosion resistance and material longevity are non-negotiable. Engineered to meet stringent mechanical standards, it supports reliable system performance in a wide range of piping environments.
