## Long description

Barrow TLQFS-V1 is a compact ball valve designed for 10 mm internal-diameter hose systems with a G1/4 threaded connection and a black finish. It provides a manual on/off control point for liquid flow in custom cooling loops, water-cooling rigs, and general fluid routing where a reliable shutoff is required. The valve is sized for 10 mm inner-diameter hoses and is intended to work together with compatible G1/4 fittings and hose clamps to maintain a leak-resistant connection.
Advantages
The valve combines a small footprint with a straightforward manual operation, offering precise shutoff without complex installation. Its G1/4 threaded interface ensures compatibility with a wide range of fittings used in PC water-cooling and laboratory setups. The black finish resists visible staining and integrates visually with dark-themed systems. Designed for hose-based circuits, the valve helps isolate sections of a loop for maintenance or modification while minimizing flow disruption when closed.
Suitable for
 Custom PC water-cooling loops using 10 mm inner-diameter hose
 Small-scale liquid routing in laboratory or prototype rigs
 Service and maintenance points for coolant drain or isolation
 Hobbyist and industrial applications requiring manual on/off control
Key specifications
 Hose compatibility: 10 mm inner diameter
 Threaded connection: G1/4
 Operation: Manual ball valve on/off
 Finish: Black
 Material: Metal body with internal sealing (materials vary by production batch)
 Mounting: Inline installation within hose runs using threaded fittings and clamps
How to use
Install the valve inline by connecting its G1/4 threaded port to a compatible fitting and secure the 10 mm inner-diameter hose to the barbed or appropriate adapter portion, using hose clamps where required. Turn the valve handle to the open position to allow flow and rotate to the closed position to stop flow. Check connections for leaks after installation and during initial operation. When isolating a loop for maintenance, close the valve fully and verify that flow has stopped before disconnecting hoses.
Usage recommendations
Use compatible G1/4 fittings and hose clamps rated for your coolant type and operating temperature. Avoid exposing the valve to fluids or temperatures beyond the manufacturer's stated compatibility for your system components. Periodically inspect seals and threaded joints for wear and replace components as needed to maintain a leak-resistant system.
