The Legend 3/4 in. FIP Pattern X 3/4 in. D CTS Pack Joint Bronze Coupling is a rugged, reliability-focused fitting designed to bridge two common plumbing worlds: iron/brass piping and copper tubing. Crafted in lead-free bronze and ANSI certified, this coupling delivers a durable, code-compliant connection you can trust in potable-water systems and more.
Why this coupling stands out
-
Two-fit versatility — one end features a 3/4" FIP (female iron pipe) threaded connection, while the opposite end is a 3/4" CTS Pack Joint compression connection, enabling seamless transitions between pipe styles without soldering.
-
Lead-free bronze — built for safety and long-term durability in drinking-water applications, with corrosion resistance that stands up to typical household conditions.
-
Compatibility you can rely on — designed to work with brass and iron pipe materials, expanding your options when upgrading or repairing existing systems.
-
Certified confidence — ANSI certification helps ensure it meets industry standards for performance and safety.
-
Ease of installation — the CTS Pack Joint side enables straightforward, tool-assisted compression installation, while the FIP end accepts standard threaded fittings, reducing the need for specialized tools or techniques.
Ideal use cases
This bronze coupling is well-suited for projects where you need to connect copper tubing to iron or brass piping, such as:
- Remodeling older homes with mixed piping materials
- Connecting a copper supply line to an iron main
- Quick, solder-free transitions in potable-water or radiant heating systems
Practical guidance for installation
- Prepare both pipe ends by cutting square and deburring to ensure a clean seal.
- For the FIP side, apply appropriate thread sealant or PTFE tape to ensure a watertight thread connection; tighten with a compatible wrench until snug, then give a firm final turn to seat properly—avoid overtightening to prevent damage.
- On the CTS Pack Joint side, slide on the compression nut and ferrule, insert the copper tube fully, and tighten the nut per standard compression-fitting practice until the line is secure and leak-free.
- Once connected, perform a gentle pressure test to confirm there are no leaks at either end.
What to expect in daily use
With its bronze construction and dual-end design, this Legend coupling delivers reliable, low-leak performance in a compact form factor. It’s ideal for homeowners tackling DIY plumbing upgrades, professional installers seeking a dependable transition fitting, and maintenance crews working on mixed-material systems. Expect consistent sealing, straightforward serviceability, and a component you can count on through seasonal temperature changes and routine system stress.
