45° Rotary Fitting for 12mm Hard Tube

The Phanteks PH-RA45_BK12 is a 45-degree rotary fitting built for 12mm hard-tube custom loops. It connects rigid tubing at an angle while allowing the joint to spin freely during assembly. The black finish matches the Glacier series aesthetic for a uniform look.

CNC Brass Body with Viton Seals Under Pressure

The fitting body is CNC-machined from solid brass and engineered for high flow. Viton seals sourced from automotive and aerospace supply chains maintain their elasticity and sealing force over long periods of heat cycling and sustained pump pressure. The rotary mechanism stays smooth without leaking when the loop runs continuously.

Satin Black Finish and Standard G1/4 Threads

The satin black coating resists fingerprints and scratches during routine handling and tube insertion. Standard G1/4 threads screw into any compatible water block, radiator, reservoir or pump top without adapters. The knurled collar provides grip for hand-tightening, so no tools are required for day-to-day maintenance or reconfiguration.

Questions about this item

Does the 45° rotary fitting add noticeable flow restriction or heat when the loop runs continuously?

The CNC-machined brass body and high-flow design keep restriction low, so the fitting does not add measurable heat or noise during all-day operation.

Which tube size and thread standard must I already have for the PH-RA45_BK12 to install correctly?

The fitting accepts 12 mm outer-diameter hard tube and uses standard G1/4 threads, so your existing tubing and water-block ports must match those dimensions.

Will this black satin rotary fitting seal reliably against older Phanteks Glacier blocks and radiators I plan to keep?

Yes, the VITON seals and G1/4 threads are designed to work seamlessly with all Phanteks water-cooling components, including earlier Glacier series parts.
