Pacific M-Pro G1/4 PETG fitting

The Thermaltake Pacific M-Pro is a black-plated copper compression fitting designed for custom water-cooling loops. It accepts rigid PETG tubing with a 16 mm outer diameter and uses a standard G1/4 thread for component connections. Enthusiast builders use it to create secure, leak-free junctions between blocks, radiators and reservoirs.

Triple O-ring seal under pressure

The fitting employs a patented triple O-ring design that maintains a tight seal when the loop reaches operating temperature and pressure. The compression mechanism distributes clamping force evenly around the tube, reducing the risk of micro-leaks that can appear after repeated thermal cycles. This construction helps the loop stay sealed during extended gaming or rendering sessions.

G1/4 thread compatibility limits

The G1/4 thread is the common standard for most water-cooling components, so the fitting works with blocks, radiators and pumps that share this pitch. It cannot be used with parts that employ different thread sizes or proprietary quick-connect systems. Builders must verify that every component in the loop matches the G1/4 specification before assembly.

Questions about this item

How much heat does the black-plated copper fitting add to a loop running all day?

The fitting itself generates no heat; it simply connects PETG tubing so the coolant can carry heat away from the components.

What tubing size must I already own for the G1/4 threads to seal properly?

You need 16 mm OD PETG tubing; the compression rings are sized for that exact outer diameter.

Will these fittings thread into the G1/4 ports on my existing radiator and water blocks?

Yes, the G1/4 BSPP threads are the standard size used on most custom-loop radiators, blocks and reservoirs.
