Pacific G1/4 Compression Fitting

The Thermaltake CL-W143-CU00BL-A is a G 1/4 compression fitting designed for rigid PETG tubing with a 12 mm outer diameter. It connects a 12 mm tube to a standard G 1/4 port in a custom liquid-cooling loop.

Suits builders using 12 mm PETG tubing

This fitting suits builders assembling a custom loop with 12 mm OD PETG tubing and G 1/4 threaded components. It does not suit builds that use soft tubing, a different outer diameter or a non-G 1/4 thread standard.

Critical spec: 12 mm applicable OD

The single specification that decides fitment is the 12 mm applicable outer diameter. Only tubing measuring exactly 12 mm OD will seal correctly in this compression fitting.

Questions about this item

Does the copper compression fitting add noticeable heat to the loop during all-day operation?

The fitting is a passive copper component that simply joins 12 mm PETG tube to a G 1/4 port; it generates no heat of its own.

Which components must already be in the loop for the G 1/4 threads on this fitting to connect?

You need a pump, reservoir, radiator and water blocks that all expose G 1/4 female ports, plus 12 mm OD PETG tubing.

Will the 20.00 x 17.00 mm body of this fitting clear older water blocks with tight port spacing?

The 20 mm by 17 mm footprint is compact, but verify the port centre-to-centre distance on your legacy blocks before installing.
