Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

STZ Industries delivers a dependable solution for branch connections with the Black Malleable Iron Reducing Tee, a three-way FIP (Female Iron Pipe) fitting that lets you split a 3/4 inch line to a 1/2 inch branch while keeping the remaining run at 3/4 inch. Crafted from durable malleable iron and finished in corrosion-resistant black, this reducer tee is built to stand up to everyday piping demands in both residential and light commercial applications. The design prioritizes reliability and long service life in real-world conditions, from basement installs to crawl space repairs.

Who benefits from this fitting? homeowners tackling DIY plumbing projects, professional plumbers upgrading water distribution networks, and contractors converting or extending old iron pipe systems. The 3/4 in to 1/2 in branching capability is ideal for feeding a secondary line to a sink, toilet, or outdoor faucet without compromising the main run. The all-FIP threaded design ensures compatibility with standard female-threaded piping, making installation straightforward with common tools and sealant products designed for metal threads.

Practical applications include:

  • Branching a primary 3/4 in water line to a smaller 1/2 in feeder for fixtures or appliances.
  • Retrofit projects where existing black iron or iron pipe systems require new branches.
  • Basement or utility room piping runs that demand a compact, robust connection.
  • Domestics or light commercial installations where lead-free compliance is important for potable water.

Installation tips for best results:

  • Use an appropriate pipe thread sealant or PTFE tape compatible with metal threads and potable water.
  • Do not exceed the rated 300 psi and 150°F to maintain a reliable, leak-free connection.
  • Ensure threads are clean and dry before assembly; tighten to the recommended torque for metal fittings to avoid cross-threading.
  • Inspect joints for leaks after pressurizing the system; retorque if necessary after the first few minutes of operation.

With its lead-free composition, durable black malleable iron construction, and a practical 3/4 in x 1/2 in reduction, this STZ Industries reducing tee is a trusted choice for solid, long-lasting piping work. It’s a smart addition to any toolkit where dependable threaded connections and versatile branching are essential.
