Why you’ll choose this reducing tee
When you need to split a 1" main line into two smaller ¾" branches, this reducing tee provides a clean, professional connection that maintains flow efficiency. The all‑FIP configuration ensures compatibility with standard iron pipe threads, reducing guesswork during installation. The black malleable iron construction offers a practical balance of strength and cost, making it a solid option for plaster-and-pipe projects, irrigation runs, or service upgrades where robust fittings are preferred.
Ideal use cases
- Branching a primary 1" line to feed two ¾" fixtures or zones in residential plumbing.
- Repairs or upgrades in service lines where durable, non-brass fittings are desirable.
- Irrigation or cold-water distribution runs that require a reliable reducing connection.
Practical installation tips
- Clean and inspect threads before assembly. Use appropriate thread sealant rated for potable water on each FIP joint.
- Align the piping to prevent cross‑threading; avoid overtightening to protect thread integrity.
- Pair with compatible FIP pipes and fittings to maintain a leak‑free system and consistent performance.
Quality and reliability you can trust
STZ Industries backs this reducing tee with practical engineering designed for real-world use. With lead-free composition, a thermal range suitable for everyday hot and cold water, and a finish built to endure, it’s a dependable choice for any project that demands a durable, proven connection.
