Bitspower BP-MBEMLA16-4P G1/4" multi-link fitting 16mm OD matte black 4-pack liquid cooler

16 mm OD multi-link fittings for custom loops

These Bitspower G1/4 inch compression fittings are built for 16 mm outer-diameter rigid tubing in custom liquid-cooling circuits. The matte-black brass bodies accept hard tube directly and lock it with a multi-link sealing design. The four-piece value pack covers a typical CPU-plus-GPU build or a single-loop expansion.

Suits builders extending rigid-tube runs.

The fittings target enthusiasts who need secure, leak-free joints between 16 mm hard-tube segments or between tube and component blocks. Installers working with PETG, acrylic or similar rigid materials will benefit. Builders who prefer flexible soft tubing or who require angled rotary adapters should look at dedicated soft-tube or rotary fitting ranges instead.

Straightforward compression install; watch tube prep

Each fitting uses a standard G1/4 thread into blocks or radiators, then a compression nut that clamps the 16 mm tube. Installation is simple: deburr and chamfer the tube end, slide the nut and olive on, then tighten by hand plus a quarter turn with a wrench. Most leaks come from un-squared cuts or missing chamfers, so take time on tube preparation.
