Computer cooling system accessory Koolance INS-FLTR03 stainless steel filter 32×23.3×23.3 mm

Koolance INS-FLTR03 stainless steel filter 32×23.3×23.3 mm is an inline accessory for computer liquid cooling systems designed to capture debris and particles circulating in the coolant. The compact metal housing combines nickel-plated brass fittings with a removable stainless steel mesh assembly containing two reusable filter elements with hole sizes of 0.42 mm² and 0.27 mm². The unit provides one male and one female G 1/4 BSPP connection for straightforward installation in the inlet of a water block, pump, or heat exchanger, and the body can be unscrewed for cleaning or filter replacement.

Advantages

The stainless steel construction and nickel-plated brass fittings ensure corrosion resistance and mechanical durability while maintaining a compact footprint. Dual reusable mesh elements allow the user to choose filtration fineness and to clean the filters without permanent replacement. G 1/4 BSPP compatibility makes the filter suitable for standard liquid-cooling fittings, and the removable body simplifies maintenance and reduces downtime for the cooling loop.

Suitable for

• Protecting pumps and water blocks in custom PC liquid cooling loops
• Installation upstream of radiators or heat exchangers to reduce clogging
• Systems that require easy-to-clean, reusable filtration

Key specifications

• Material: stainless steel mesh with nickel-plated brass fittings
• Filter elements: two reusable stainless steel meshes with 0.42 mm² and 0.27 mm² hole sizes
• Connections: one male and one female G 1/4 BSPP
• Dimensions: 32 mm × 23.3 mm × 23.3 mm (width × depth × height)
• Design: inline, unscrewable body for cleaning and replacement

How to use

Install the Koolance INS-FLTR03 inline in the coolant loop where you want to intercept particles — typically on the inlet side of a pump, water block, or before a radiator. Use standard G 1/4 BSPP fittings to connect the male and female ports into the loop. Periodically unscrew the filter body, remove the mesh elements and rinse them under running water or use a mild cleaning solution if necessary; allow the meshes to dry fully before reassembly. Reinstall the filters and tighten fittings to the recommended torque for your fittings to avoid leaks.

Usage recommendations

For optimal reliability, check the filter during regular system maintenance intervals and clean the finer 0.27 mm² mesh more frequently in systems with particulate buildup. Avoid using aggressive chemicals that may damage seals or plated surfaces; use warm water or a mild detergent for cleaning and ensure all components are dry before returning the system to service.
