Common Applications

The B-WCF is a black filtration cotton insert sized to drop into water cooling reservoirs with a 50mm internal diameter. Once seated inside the tank, it traps loose debris that can otherwise circulate through the loop - shed o-ring fragments, machining swarf from new blocks, dust drawn in during fill, and residue from coolant break-in. The cotton is removable for inspection and replacement during routine flushes, which keeps narrow channels in CPU and GPU blocks clear and protects the pump impeller. Sold as the filter cotton only - not a complete reservoir.

Q: Is it reusable?

A: It can be rinsed and reinstalled during flushes, but most users replace it on a regular maintenance cycle for best filtration.
