Precision 45-Degree Hard-Tube Adapter

The Phanteks PH-A45_BK_12 is a 12 mm hard-tube fitting angled at 45 degrees for custom water-cooling loops. It suits builders who need a clean directional change without adding extra tubing length. The satin-black finish matches other Glacier-series components for a uniform look. It is not for systems using soft tubing or larger-diameter rigid pipe.

Tool-Free Installation With Compression Rings

Each adapter uses a compression-ring design that secures 12 mm tubing by hand, eliminating the need for special tools or heat-forming. The CNC-machined brass body threads into standard G1/4 ports found on most blocks, radiators and reservoirs. Over-tightening can damage the VITON O-rings, so firm finger pressure is sufficient. Builders unfamiliar with hard-tube alignment should dry-fit the run before final tightening.

Sustained Flow Stability Under Load

The high-flow internal geometry maintains consistent coolant velocity during extended gaming or render sessions, reducing the risk of localized hot spots. VITON seals sourced from automotive and aerospace supply chains resist degradation from temperature cycling and common coolant additives. The brass construction dissipates heat evenly, preventing thermal stress on the joint during prolonged operation. No performance drop-off is observed compared to straight fittings in the same loop.

Questions about this item

How can I confirm the 45-degree 12mm hard tube adapter is seated correctly after installation?

Check that the VITON sealing ring sits flush inside the CNC-machined brass body and that the tube inserts fully until it bottoms out; a steady system pressure test with no leaks confirms proper seating.

What comes in the package and what must I purchase separately for a custom loop?

The box contains the black 45-degree adapter fitting only; 12mm hard tubing, coolant, pump, radiator, reservoir and any additional straight or angled fittings are sold separately.

Which finish should I choose between Satin Black and Mirror Chrome for a Phanteks Glacier loop?

Select Satin Black to match the PH-A45_BK_12 model code and keep a uniform stealth aesthetic across all Glacier fittings in the build.
