Legend Valve 313-515 Pack-Joint Nut 1" CTS

1" CTS Pack-Joint Nut

This Legend Valve 313-515 pack-joint nut fits 1" copper tube size connections in plumbing systems. It is a bronze assembly designed to join service lines without threading or soldering. Professional installers and maintenance crews use it for water service repairs and new installations. The component ships directly from the manufacturer.

Replaces worn or damaged pack-joint nuts

When an existing nut corrodes, cracks or leaks at the joint, this assembly restores the seal. The jump is worth it when the old nut can no longer hold pressure or when a service line is being upgraded to CTS specifications. It is not for installations requiring threaded, flanged or compression fittings of a different standard. Buyers needing a different pipe size or material should select the matching component.

Bronze construction holds under constant pressure

The nut maintains its seal under sustained line pressure and ground movement without the relaxation seen in softer alloys. It resists dezincification and stress corrosion in potable water service. The fitting is not designed for high-temperature hydronic loops or gas distribution. California Proposition 65 warnings apply for chemicals known to cause cancer and birth defects.
