The Febco Lead-Free Brass Ball Valve is a professional-grade isolation valve designed for long-term reliability in high-pressure irrigation and potable water systems. Engineered as a full-port shut-off, this valve allows for maximum water flow with virtually zero resistance, making it an ideal choice for the primary inlet of your backflow preventer or main distribution header.
Constructed from durable, lead-free brass, this valve is one of our most trusted irrigation fittings for systems requiring strict compliance with state and federal lead-free standards. Its rugged design handles pressure surges and constant use, providing a "bubble-tight" seal that prevents leaks and ensures your system remains fully isolated when maintenance is required.

Install your isolation valve correctly to prevent leaks.
Step 1: Check Flow Direction
While ball valves are generally bi-directional, it is best practice to install with the handle opening toward the water flow. Inspect threads for any debris.
Step 2: Apply Sealant
Apply 3-4 wraps of thread seal tape to the male threads of your pipe. Clockwise wrapping ensures the tape doesn't unravel during tightening.
Step 3: Hand Tighten First
Screw the valve onto the pipe by hand until snug. This prevents cross-threading of the brass body.
Step 4: Secure with Wrenches
Use a pipe wrench or adjustable wrench on the valve's hex flats. Tighten 1-2 additional turns. Do not over-tighten, as this can crack the brass body or damage the internal seals.
Ensure your mainline setup is secure with these essential parts:
