This Legend bronze coupling is particularly well-suited for repairs and retrofits where a copper-tube sized (CTS) connection must join to a threaded pipe. It’s a practical choice for basement or crawl-space repairs, laundry lines, or updating old iron piping to a more modern copper-tube connection without sacrificing durability.
Ideal use scenarios: replacing a corroded NPT-friendly segment on a water line, connecting a copper tube run to a brass or iron nipple, or consolidating mixed-material piping in a compact, serviceable joint.
Practical installation tips: On the MNPT end, apply an appropriate thread sealant (such as PTFE tape) and thread into the mating fitting until snug. On the CTS Pack Joint end, insert the copper tube fully into the joint and tighten the compression mechanism per your system’s specifications to achieve a reliable seal. Always verify leaks after installation and avoid overtightening bronze fittings to preserve seating and longevity.
