Legend Valve 313-516 CTS Pack-Joint Nut

The Legend Valve 313-516 is a 1-1/4" CTS bronze pack-joint nut assembly designed for copper tube size plumbing connections. It provides a reliable mechanical joint for installers joining CTS tubing in water service applications. The bronze construction resists corrosion in potable water systems. This fitting suits professional plumbers and maintenance crews needing a dependable pack-joint connection.

Bronze construction handles standard water service

The bronze body handles typical municipal water pressures found in residential and light commercial service lines. It accommodates 1-1/4" CTS tubing for secure pack-joint assembly without specialized threading tools. The nut assembly simplifies installation on copper or compatible plastic tubing. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm.

Replaces worn or damaged pack-joint nuts on CTS

This assembly replaces deteriorated pack-joint nuts on existing 1-1/4" CTS service connections during repair or retrofit work. The upgrade is worthwhile when the original nut leaks, seizes or shows corrosion that compromises the seal. It restores joint integrity without replacing the full fitting body. Buyers needing other tubing sizes or compression-style connections will require different fittings.

Questions about this item

Will the 1-1/4" CTS bronze pack-joint nut assembly thread onto my existing copper tubing without leaks?

The 1-1/4" CTS bronze pack-joint nut assembly is sized for standard copper tubing size and uses a compression-style seal that mates with existing CTS pipe when installed correctly.

How can I confirm the 313-516 pack-joint nut assembly is seated and sealing properly after installation?

Pressurise the line and inspect the joint; a properly seated 313-516 assembly shows no drips or weeping at the nut-to-pipe interface under normal working pressure.

Does the Legend Valve 313-516 box include the gasket or washer, or must I buy a separate sealing component?

The pack-joint nut assembly ships as a complete unit with the nut and integral sealing components; no separate gasket or washer purchase is required.
