Bitspower Multi-Link Adapter G1/4 inch male to 16mm OD hardtube straight fitting, glossy black

Bitspower Multi-Link Adapter G1/4" male to 16mm OD hardtube straight fitting, glossy black is a compact straight fitting designed to connect 16 mm outer-diameter hard tubing to standard G1/4" ports in PC liquid-cooling systems. Finished in glossy black, the adapter provides a rigid, low-profile transition between components such as radiators, pumps, reservoirs and distribution plates. The fitting is intended for custom water-cooling loops where a secure, leak-resistant connection to 16 mm hardtube is required.

Advantages

The fitting offers a direct, space-efficient connection between a G1/4" threaded port and 16 mm OD hard tubing, reducing the need for additional intermediate fittings. Its glossy black finish matches common water-cooling hardware aesthetics and provides corrosion-resistant surface treatment. The straight design limits flow disturbance and maintains a clean, linear layout for hardtube runs while ensuring mechanical stability at the joint.

Suitable for

• Custom PC water-cooling loops using 16 mm hard tubing
• Connections to radiators, pumps and reservoirs with G1/4" ports
• Tight or low-profile build areas where a straight, compact adapter is needed
• Systems requiring a stable, rigid transition between threaded ports and hardtube

Key specifications

• Thread type: G1/4" male
• Hardtube compatibility: 16 mm outer diameter
• Orientation: straight fitting
• Finish: glossy black
• Application: PC liquid-cooling / water-cooling loops

How to use

Thread the G1/4" male end into a compatible G1/4" female port by hand, then tighten securely with an appropriate tool if required, taking care not to overtighten. Insert the 16 mm OD hardtube into the straight end and secure according to the tube type and sealing method recommended for hardtube connections (for example, using compatible compression rings, clips or adhesive as applicable). Verify alignment to prevent stress on the tubing and check for leaks after filling the loop.

Recommendations

Before final assembly, test-fit components to confirm clearance in your case and ensure the glossy black finish matches other fittings. Use appropriate sealing practices for hardtube installations, follow manufacturer guidelines for torque on G1/4" threads, and perform a pressure or leak test on the filled loop before powering the PC.
