Valve Type and Application
The Legend Valve 101-580NL is a 1/2 inch T-805 forged brass ball valve designed for PEX piping systems. It connects male NPT threads to PEX tubing in residential or commercial plumbing installations. The no-lead construction meets regulatory requirements for potable water use. It serves plumbers and contractors needing a reliable shut-off valve.
Build Quality and Connection Method
Forged brass construction provides structural strength for pressured water lines. The male NPT inlet threads into standard fittings while the PEX end accepts crimp or clamp connections. This combination allows direct transition between threaded pipe and PEX without extra adapters. The quarter-turn handle enables quick flow control during maintenance or emergencies.
Regulatory Limits and Usage Constraints
California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm. Installers should follow safe handling practices and local codes for potable water systems. The valve is intended for standard plumbing pressures and temperatures only. It does not suit applications requiring certified lead-free documentation beyond the no-lead designation.

Questions about this item
What connection standard does the 1/2" T-805 No Lead valve use on its MIP side?
The MIP side uses a male iron pipe thread that seals on tapered threads with sealant or tape, capping the joint at the rated pressure of the piping system.
What pipe or tubing sizes must be present for this valve to fit?
It requires a 1/2" female NPT fitting on one side and 1/2" PEX tubing with a compatible crimp or clamp ring on the other.
How is the PEX end of this valve installed, and what step is often missed?
Slide the correct 1/2" PEX ring onto the tubing, insert the valve barb fully, then crimp or clamp the ring — skipping the go/no-go gauge check is the common error.
