Legend Valve LEG301-105NL No Lead Dielectric Union 1 Inch Fnpt X Sweat

Product Description

The Legend Valve LEG301-105NL is a no lead dielectric union designed for connecting dissimilar metals in plumbing and HVAC piping systems. It measures 1 inch in size and features a female national pipe thread (FNPT) connection on one end and a sweat (solder) connection on the other, making it a versatile fitting for mixed-material installations. Plumbers, mechanical contractors, and HVAC technicians rely on dielectric unions to prevent galvanic corrosion, which occurs when two different metals come into direct contact in the presence of water. Without a dielectric union, this electrochemical reaction can cause pipe and fitting degradation over time, leading to leaks and costly repairs. The LEG301-105NL isolates copper and iron or steel piping with a built-in insulating sleeve and washer, blocking the flow of electrical current between the two metals. This union is rated for a maximum temperature of 180 degrees Fahrenheit and a cold working pressure (CWP) of 200 PSI, making it suitable for domestic water supply, hydronic heating, and general commercial plumbing applications. The no lead construction complies with lead-free standards required for potable water systems, including those governed by state and federal safe drinking water regulations. The FNPT x sweat configuration allows straightforward installation in standard residential and light commercial piping systems. This fitting is a direct drop-in solution for retrofit and new construction jobs where copper meets galvanized or black iron pipe. It is built to withstand the demands of everyday trade use and delivers reliable long-term performance in both hot and cold water lines.

• No lead construction meets lead-free requirements for potable water applications
• Rated for 180 degrees Fahrenheit maximum temperature and 200 PSI cold working pressure
• FNPT x sweat configuration connects threaded iron or steel pipe to copper tubing

Product Highlights

The Legend Valve LEG301-105NL dielectric union provides dependable galvanic corrosion protection in 1 inch FNPT x sweat installations, built to no lead standards for safe use in potable water systems.
