1/2 inch x 60 inch Galvanized Steel Nipple

1/2" x 60" Galvanized Steel Nipple – Threaded Extension for Low-Pressure Piping Systems

The 1/2" x 60" Galvanized Steel Nipple is a schedule 40 straight pipe section with male NPT threads on both ends, engineered for use in water supply, HVAC distribution, and other low- to moderate-pressure plumbing systems. Manufactured from welded steel tubing and hot-dip galvanized to ASTM A153 specifications, this nipple provides extended reach while offering corrosion resistance in non-aggressive environments.

With precision-formed threads and uniform wall thickness, it ensures compatibility with standard galvanized or black iron female-threaded fittings. The 60-inch length makes it ideal for applications requiring long inline extensions, risers, or offsets without the need for multiple joints.

Product Features

• ✅ Hot-Dip Galvanized Coating Protects against rust in wet and humid environments, improving system longevity.
• ✅ Schedule 40 Wall Thickness Suitable for general-purpose fluid handling, including potable water and low-pressure gas systems.
• ✅ Threaded Male x Male Ends Cut to NPT standards for leak-resistant sealing when installed with approved pipe sealants.
• ✅ Extended Length Reduces the need for couplings in long spans, minimizing potential leak points.
• ✅ Machined to Industry Tolerances Ensures consistent fit and alignment with mating components.

Technical Specifications

• Material: Welded steel with zinc galvanization (ASTM A53 Type F or equivalent)
• Nominal Size: 1/2 inch
• Overall Length: 60 inches
• Thread Type: Male NPT x Male NPT
• Compliance: Meets ASTM A733 for pipe nipples and ASME B1.20.1 for threading

Installation Guidance

Apply PTFE tape or thread compound rated for galvanized steel prior to assembly. Tighten using a properly sized pipe wrench at the pipe body, avoiding overtightening to preserve thread integrity. For systems with thermal cycling or pressure testing requirements, ensure joints meet required torque specifications.

Typical Applications

This galvanized nipple is widely used in mechanical systems requiring pipe extensions, including water heater hookups, system branch runs, pump discharge lines, and HVAC service loops. It is suitable for indoor and outdoor use in non-corrosive environments. For systems with continuous exposure to moisture or aggressive media, alternative coatings or materials may be recommended.

Material Insight

Galvanized steel is favored for threaded pipe assemblies due to its mechanical strength, ease of fabrication, and protective zinc layer. Hot-dip galvanization provides sacrificial corrosion protection, making it appropriate for exposure to atmospheric moisture and intermittent water contact.

The 1/2" x 60" Galvanized Steel Nipple delivers a reliable, code-compliant solution for extending pipe runs in pressure-rated mechanical, plumbing, and process piping systems. Designed for performance, it minimizes field joints while maintaining structural integrity and resistance to corrosion.
