Adapter 90° BitsPower Advanced Multi-Link G1/4 inch AG to 12mm OD Hardtube, rotatable

BitsPower Advanced Multi-Link 90° adapter converts a standard G1/4" male (external) thread to accept 12mm outside-diameter (OD) hard tubing, creating a compact, angled connection for custom liquid-cooling loops. The rotatable 90-degree fitting is designed to provide a sealed transition between a G1/4" port and rigid 12mm tube, enabling tight routing and precise alignment in confined spaces of PC water-cooling systems.

Advantages

The adapter’s compact 90° profile reduces stress on tubing and fittings and allows for cleaner cable- and tube-routing in tight chassis areas. Its rotatable joint makes it possible to fine-tune tube orientation after installation without disconnecting the entire assembly. The design provides a reliable, sealed connection suited for rigid 12mm hardtubes and standard G1/4" threads, helping maintain leak-free performance when installed correctly.

Suitable for

• Custom PC water-cooling loops with rigid 12mm OD hard tubing
• Tight or compact cases where straight fittings cannot achieve required bends
• Components with standard G1/4" ports such as radiators, reservoirs, pumps, and blocks
• Setups requiring post-installation orientation adjustment of tubing

Key specifications

• Connection type: G1/4" male (external) to hardtube 12mm OD
• Angle: 90 degrees, rotatable joint for alignment
• Material: corrosion-resistant metal suitable for liquid-cooling use
• Sealing: integrated sealing surfaces for leak-resistant installation
• Compatibility: designed for rigid hard tubing with 12mm outside diameter

How to use

Screw the adapter into a component’s G1/4" female port by hand to start, then tighten securely with an appropriate tool without over-torquing. Insert and secure the 12mm OD hardtube into the adapter according to the hardtube fitting method used (compression or clamping as required by your system). Rotate the fitting body to the desired orientation before final tightening to achieve the proper tubing routing and alignment, ensuring seals are seated and the connection is leak-free.

Recommendations

Inspect all sealing surfaces and O-rings before installation, use compatible coolant and tubing materials, and perform a pressure or leak test after assembly. Do not overtighten threads; follow component manufacturer torque guidance where available to avoid damage.
