3/4 inch x 8 inch Galvanized Steel Nipple

3/4" x 8" Galvanized Steel Nipple – Threaded Pipe Extension for Corrosion-Resistant Piping Systems

The 3/4" x 8" Galvanized Steel Nipple is a threaded pipe segment designed for use in fluid and air distribution systems requiring enhanced corrosion resistance. Constructed from welded or seamless carbon steel pipe and coated with a zinc layer via hot-dip galvanization, this fitting supports reliable connections in environments exposed to moisture or mild chemicals.

With male National Pipe Tapered (NPT) threads on both ends, this nipple allows for direct integration into galvanized or compatible threaded systems. Its 8-inch length is commonly used to extend pipe runs or connect valves, fittings, and equipment over short distances where precision spacing is required.

Performance Characteristics

• ✅ Material: Carbon steel with hot-dip galvanized coating (ASTM A53 or A733 depending on manufacturer)
• ✅ Thread Standard: NPT (male x male), conforming to ASME B1.20.1
• ✅ Nominal Pipe Size: 3/4 inch
• ✅ Overall Length: 8 inches
• ✅ Wall Thickness: Schedule 40 (standard weight)
• ✅ Pressure Rating: Suitable for WOG (water, oil, gas) applications; rating depends on system design and service conditions

Common Applications

• Used in potable and non-potable water systems where rust prevention is critical
• Installed in residential and light commercial plumbing systems, irrigation piping, and air compressor lines
• Appropriate for indoor and outdoor use where threaded galvanized connections are required

Installation Guidelines

Apply PTFE tape or approved thread sealant to male threads to ensure a secure, pressure-tight seal. Align carefully to prevent cross-threading. Use appropriate wrenches to maintain integrity without over-tightening, which could damage threads or fittings.

Code Compliance

This nipple meets applicable dimensional and threading standards for galvanized steel fittings and is suitable for use in systems built to meet IPC, UPC, and local code requirements when properly applied.

The 3/4" x 8" Galvanized Steel Nipple offers a corrosion-resistant solution for threaded pipe extensions in structural and plumbing systems. Its durable zinc-coated construction and industry-compliant threading make it suitable for demanding installation environments.
