This nickel plated brass L Port valve is ideal for installations where multi-lines are required from one tank. Suitable for diesel and petrol (gasoline) applications. The L port configuration allows one threaded female port to feed in, and two threaded female ports to feed out, which can be operated one at a time, but not together. We also supply compression fittings, hose tails and fittings to complete your installation. This ball valve has a reduced passage leading to higher pressure.
