Bitspower BP-BSEMLA12-4P 12mm OD rigid tubing fittings 4-pack

Multi-Link Fittings for 12mm OD Hard Tubing

This four-pack of Bitspower G1/4" compression fittings is built for custom liquid-cooling loops that use 12mm outer-diameter rigid tubing. The brass construction and Black Sparkle finish suit enthusiasts assembling a clean, monochrome build. Each fitting accepts a single hard-tube run and threads into any standard G1/4" port on blocks, radiators or reservoirs.

Replaces Standard Single-Connection Fittings

The multi-link design lets you join tubing segments in a straight line without adding extra angled adapters, reducing potential leak points and visual clutter. The upgrade is worthwhile when you need to span longer distances between components or want a cleaner tube run than two separate fittings and a coupler can provide. Builders staying with soft tubing or smaller diameters will not benefit from this specific fitting.

Straightforward Compression Install

Slide the compression nut and olive onto the cut tube, press the tube fully into the fitting body, then hand-tighten the nut before a final quarter-turn with a wrench. The most common issue is an uneven tube cut that prevents a complete seat, causing a slow weep under pressure. Deburring the inside and outside edges and double-checking insertion depth before tightening eliminates the problem.
