The 1/2" Loc-Line® (2) Check Valves In-Line Check Valves. (Pack Of 2) Check Valves Loc-Line® Usa #32091 (Part #32091) Is A Loc-Line® Modular Inline Flow Control Valve Designed To Provide Precise On/Off And Throttling Control Of Coolant, Air, Or Fluid Directly Within A Compatible Loc-Line Modular Hose System. Installed Inline Between Hose Segments Or At The Point Of Use, This Valve Allows Operators To Quickly Adjust Or Shut Off Flow, Improving Visibility, Reducing Waste, And Enhancing Overall Machining Efficiency.

• Inline flow control and shut-off valve for Loc-Line modular hose systems
• Allows quick on/off control or fine flow adjustment at the machine
• Integrates directly inline with compatible Loc-Line hose components
• High-strength acetal construction resists coolants, oils, and shop chemicals
• Maintains set position under vibration and continuous operation
• Ideal for CNC machines, manual mills, lathes, and industrial equipment

This item is part of our complete offering of Loc-Line Modular Hose Systems, the industry-standard solution for precise coolant, air, and fluid delivery in CNC machining and metalworking applications. Built with a unique ball-and-socket design, Loc-Line systems provide fully adjustable positioning that stays in place under vibration and high flow conditions, allowing you to direct coolant exactly where it is needed without constant readjustment. These modular hose systems improve tool life, chip evacuation, and machining accuracy while offering easy snap-together customization with nozzles, valves, fittings, and manifolds. Browse our full selection of Loc-Line Systems, or explore our Loc-Line Coolant Hose Systems category to find the right size, configuration, and components for your application.

Loc-Line modular hose systems are available in multiple sizes including 1/4" Loc-Line, 1/2" Loc-Line, and 3/4" Loc-Line to match different flow rates and pressure requirements, making them ideal for everything from light-duty air applications to high-pressure coolant delivery in CNC machining centers. With a wide range of interchangeable components such as round nozzles, flat nozzles, Y-connectors, valves, and magnetic bases, these systems can be configured for single or multi-directional flow to improve chip control, reduce heat buildup, and extend tool life. Use the filters to quickly find the right Loc-Line configuration by size, connection type, nozzle style, and application to optimize your setup.
