    Precision Flow-Adjustment Valves with Barbed Fittings for Fuel

    Add fine flow control to tubing lines for butane, diesel fuel, fuel oil, gasoline, kerosene, natural gas, and propane. These valves have a barbed fitting that grips onto tubing, providing a secure hold. Turn the handle to adjust flow in small increments. Valves have metal-to-metal seats that resist temperature fluctuations.

    Precision Flow-Adjustment Valves with Compression Fittings

    The compression sleeve on these valves bites into tubing as you tighten the nut, forming a strong seal. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. All have metal-to-metal seats that resist temperature fluctuations.
