3/4" CTS Pack-Joint Nut

The Legend Valve 313-514 is a bronze pack-joint nut assembly designed for 3/4 inch CTS connections. It serves as a component for joining copper tube size piping in plumbing installations. Professional plumbers and maintenance technicians use this fitting to create secure joints. The product is supplied new and ships directly from the manufacturer.

Replaces worn or damaged pack-joint nuts

This assembly replaces an existing 3/4" CTS pack-joint nut that has corroded, cracked or stripped during service. The upgrade is worth it when the original fitting leaks at the connection point or can no longer maintain a tight seal. It restores joint integrity without requiring a full pipe replacement. California Proposition 65 warnings apply as the product contains chemicals known to cause cancer and birth defects.

Bronze construction handles sustained pressure

The bronze body resists deformation under continuous system pressure and thermal cycling better than softer alloys. It maintains clamping force on the gasket during extended service rather than relaxing after initial tightening. The material withstands the chemical exposure typical in potable water lines. Orders of $75 or more qualify for free shipping from the supplier.

Questions about this item

What pipe size does the 3/4 inch CTS pack-joint nut fit?

The 3/4 inch CTS designation means it fits copper tubing size with a 3/4 inch nominal outside diameter, standard for residential water service lines.

How is the pack-joint nut installed and what step is often missed?

Slide the nut onto the pipe, insert the gasket and compression ring, then tighten the nut onto the fitting body; the step often missed is ensuring the gasket seats evenly before final torque.

What maintenance or replacement will the bronze pack-joint nut need over time?

Inspect the gasket for cracking or leakage during routine checks; replace the gasket if water seeps at the joint, while the bronze nut itself typically lasts the life of the service line.
