Galvanized Pipe & Fittings

Galvanized Pipe & Fittings offer durable, corrosion-resistant solutions for plumbing and outdoor projects. The hot‑dip zinc coating shields the steel from moisture, making them a strong choice for exterior water lines, hose bibs, sprinkler risers, barns, garages, and coastal installations. With standard NPT threads and consistent sizing, galvanized pipe and threaded fittings assemble quickly and reliably, giving you tight, leak‑resistant joints that stand up to weather and wear.

Shop common sizes from 1/2 in. to 2 in., in straight lengths and ready‑to‑use nipples, along with elbows, tees, couplings, unions, caps, bushings, crosses, flanges, and hangers. Many products meet ASTM specifications; for drinking water, look for lead‑free and NSF/ANSI 61 certifications. Schedule 40 galvanized steel is popular for general service; schedule 80 increases wall thickness for added pressure and impact tolerance.

Installation is straightforward:
- Cut square and deburr the pipe to protect threads.
- Use PTFE tape followed by a compatible pipe thread sealant for best results.
- Tighten with two wrenches to avoid stressing adjacent joints.
- Coat field‑cut ends with a cold‑galvanizing compound to maintain corrosion resistance.
- Use dielectric unions when transitioning to copper or brass to reduce galvanic corrosion.

Typical applications include residential and commercial water distribution, outdoor spigots, irrigation manifolds, wash‑down stations, and light structural uses like handrails and supports. Many pros also choose galvanized fittings for exposed locations where appearance and longevity matter. Always verify local code; galvanized pipe is generally not approved for natural gas, and some jurisdictions limit its use for potable systems.

Whether you are repairing an older galvanized line or building a new, rugged water run, this category brings together the pipe, fittings, and installation accessories you need for a clean, dependable build, backed by corrosion resistance, easy threading, and broad availability.
