Barrow G1/4''Thread 45 Degree Fitting Adapter Water Cooling, Adaptors Water Cooling Fitting, TDWT45-B01

A 45-degree fitting adapter is one of the most underrated tools in a custom loop builder's kit. Where a straight fitting would force the tubing to bend at an awkward angle — stressing the tube, restricting flow, and pushing against adjacent components — the Barrow TDWT45-B01 redirects the exit path cleanly with no added stress on the connection.

In compact workstation cases built for 24/7 AI inference, space is always a constraint. GPU blocks, CPU blocks, pump/reservoir combos, and radiator ports all occupy fixed positions, and the tubing routing between them rarely falls at convenient angles. The TDWT45-B01 gives you a precise 45-degree pivot at any G1/4 port, which is often the difference between a routing that works and one that fights you every step of the way.

Full metal construction, G1/4 threading on both sides, and compatibility with Barrow, Bykski, EK, and FormulaMod components. Whether you are building new or rerouting an existing loop after adding a second GPU for more local inference capacity, this fitting is a simple part that solves a real spatial problem.
