PHANTEKS angled rotary fitting PH-RA45_BK16 for 16mm tubing, 45° G1/4" black

PHANTEKS angled rotary fitting PH-RA45_BK16 for 16mm tubing, 45° G1/4" black is a metal connector designed for custom PC liquid cooling loops. It fits rigid 16 mm outer diameter tubing and uses a G1/4" threaded interface to connect to water blocks, radiators, pumps and reservoirs. The 45° angle and rotatable joint simplify tubing routing, reduce torsion on connections and help achieve neat, compact loop layouts while the black finish provides a discreet appearance that matches many system builds.

Advantages

The rotatable joint allows precise orientation after installation, minimizing stress on the tubing and mating ports. Metal construction provides mechanical strength and wear resistance for repeated assembly and disassembly. The 45° angle enables smoother directional changes compared with straight fittings, reducing the need for multiple adapters and helping maintain flow integrity. Compatibility with G1/4" threaded ports ensures broad interoperability with standard PC water-cooling components.

Suitable for

• Custom PC water-cooling loops using rigid 16 mm tubing
• Connecting radiators, CPU/GPU water blocks, pumps and reservoirs with G1/4" ports
• Tight or compact PC cases where angled routing is required
• Systems where frequent assembly or orientation adjustments are anticipated

Key specifications

• Tubing outer diameter compatibility: 16 mm rigid tubing
• Thread type: G1/4" female/male compatible threaded interface
• Angle: 45° directional fitting
• Feature: rotatable joint for post-installation orientation
• Material: metal construction with black finish

How to use

Thread the fitting into a compatible G1/4" port on a radiator, block, pump or reservoir until hand-tight, then secure with a wrench if required while avoiding overtightening. Insert and cut rigid 16 mm tubing to the desired length, deburr and chamfer the ends for a proper seat. Slide the tubing into the fitting and rotate the joint to achieve the correct orientation for routing before fully tightening any compression rings or locking mechanisms. Verify all connections are secure and perform a leak test according to standard liquid-cooling procedures before powering the system.

Usage recommendations

Use with properly prepared rigid 16 mm tubing and compatible G1/4" components. Ensure tubing ends are clean, square and chamfered to prevent sealing issues. When tightening, apply moderate torque and re-check orientation after initial leak testing. Avoid using incompatible sealants or excessive force that could damage threads or the fitting finish.
