3/4 inch x 6 inch Galvanized Steel Nipple

3/4 Inch x 6 Inch Galvanized Steel Pipe Nipple – NPT Threaded

The 3/4 inch x 6 inch Galvanized Steel Nipple is a straight pipe fitting used to extend or connect sections of threaded pipe in water, gas, air, or low-pressure steam systems. Fabricated from Schedule 40 welded or seamless steel pipe and hot-dip galvanized to resist corrosion, this nipple meets dimensional and mechanical requirements for general-purpose plumbing and mechanical systems.

Construction and Standards

Produced to standard industry specifications, this fitting features tapered National Pipe Thread (NPT) ends on both sides for compatibility with cast iron, steel, and brass components. Its galvanized coating conforms to ASTM A153, offering protection against oxidation in humid or outdoor environments.

• ✅ Material: Carbon Steel, hot-dip galvanized
• ✅ Nominal Size: 3/4 inch
• ✅ Length: 6 inches (measured thread-to-thread)
• ✅ Thread Standard: ANSI/ASME B1.20.1 (NPT)

Typical Applications

This nipple is used to join two female-threaded components in straight runs, transitions, or extensions. Common applications include water distribution lines, compressed air piping, irrigation headers, fire protection systems (non-critical), and process piping in industrial environments. Suitable for both indoor and protected outdoor use.

Installation Guidelines

Apply pipe joint compound or PTFE tape to threads before assembly. Align threads carefully to avoid cross-threading. Tighten using pipe wrenches; avoid over-torquing to prevent distortion of threads or mating parts. This product is not recommended for use with acidic fluids or in environments that compromise galvanized coatings.

• ✅ Sealant Required: Thread sealant or PTFE tape for leak resistance
• ✅ Torque Guidelines: Hand-tighten, then apply 1–2 additional turns with wrench
• ✅ Thread Engagement: Full thread contact recommended to meet pressure ratings

Performance Attributes

• ✅ Corrosion Protection: Zinc coating prevents premature degradation in non-aggressive environments
• ✅ Mechanical Integrity: Threaded connections maintain pressure containment up to 150 PSI (varies by system design)
• ✅ Versatility: Compatible with steel, galvanized, and brass threaded fittings

The 3/4 inch x 6 inch Galvanized Steel Pipe Nipple provides a code-compliant, durable solution for pressure and non-pressure piping installations. Engineered to meet dimensional and performance standards for a wide range of mechanical and plumbing systems, it ensures dependable connections in both temporary and permanent assemblies.
