Need to water two areas with different watering needs? You can use the Compression Inline Valve to control the flow of water to two separate watering circuits, irrigation zones, or different types of plants from one valve. Adjust, balance, or shut off water with a twist of the dial. Ideal for flower beds, vegetable gardens, trees, shrubs, and container plants. Compression fittings on both sides of the valve accommodate 1/2 in. supply tubing with 0.700 in. outside diameter (OD). The 1/2 in. Compression Inline Valve is made of ABS treated with UV inhibitors.
