This is an adapter for connecting acrylic tubes in a water cooling circuit. The in-house Crystal Link Tubes are particularly well-suited for this purpose and can, for example, be used to link two graphics cards, bridging the distance between them.

For use in a CrossFire/SLI connection, two of these adapters are required, as each of the two graphics cards must be equipped with one. The multi-link adapter features a standardized G1/4-inch external thread.

Additionally, the multi-link connections are compatible with Bitspower's Crystal Link Tubes.
