Adapter 90° BitsPower Advanced Multi-Link G1/4 inch AG to 16mm OD Hardtube, rotatable

BitsPower Advanced Multi-Link 90° adapter provides a rotatable angled connection from a G1/4" external thread to a 16 mm outer-diameter hardtube. Designed for custom PC liquid-cooling loops, this fitting allows a compact 90-degree turn in hardline runs while maintaining a secure, leak-resistant connection. The rotatable head helps align tubing during installation and reduces stress on joints, supporting precise routing in tight spaces without deforming rigid tubing.

Advantages

The adapter offers a stable mechanical connection between a standard G1/4" port and 16 mm hard tubing, with a rotatable joint to simplify alignment and installation. Its angled design preserves hardtube shape by eliminating the need to bend rigid tubing, and it reduces the number of fittings needed for tight turns. Machined surfaces and thread compatibility ensure reliable sealing when paired with appropriate O-rings or sealing methods used in PC water-cooling systems.

Suitable for

• Custom PC liquid-cooling loops using 16 mm OD hard tubing
• Situations requiring a compact 90° change of direction for hardline runs
• Builds where rotatable fittings simplify alignment and reduce joint stress

Key specifications

• Connection type: external G1/4" thread to 16 mm outer-diameter hardtube
• Angle: 90° rotatable fitting
• Material compatibility: suitable for use with rigid hard tubing and standard water-cooling sealing components
• Function: enables compact routing and secure hardtube joins without bending tubing

How to use

Install the adapter by threading the G1/4" external portion into a compatible port using appropriate sealing (O-ring or PTFE tape as required by the system). Slide the 16 mm hardtube into the tube side and secure according to the tubing collar or compression mechanism provided by the fitting design. Rotate the angled head to align tubing before final tightening to ensure correct orientation and avoid over-torquing; verify sealing and perform a pressure or leak test before powering the system.

Recommendations

Use with hard tubing specified as 16 mm outer diameter and ensure all mating threads and O-rings are clean and undamaged. Tighten fittings progressively and test the loop for leaks after installation. Avoid excessive force when aligning the rotatable joint to prevent thread or seal damage.
