80 mm CTR Hard-Mount Reservoir

The PrimoChill CTR Phase II is a compression-tube reservoir built for custom water-cooling loops. Its white POM end caps use compression rings to seal the acrylic tube without cutting or tapping. The design prevents tube stress and cracking while allowing easy colour coordination for modders.

Modders wanting tool-free tube sealing

Builders who prefer traditional threaded reservoirs or need a different inner diameter should consider other designs. The compression-ring system suits those who want quick assembly and disassembly without specialised tools. It is less suited for loops requiring non-G 1/4 port spacing.

57 mm inner diameter and G 1/4 threads

The reservoir tube measures 57 mm inside and 63 mm outside with a 118 mm body length; end caps add 38 mm for a 158 mm total. Four low-profile port caps and two three-port mountable end caps with G 1/4 threads are included for direct fitting attachment.

Questions about this item

What is the outer diameter of the acrylic tube that must clear the mounting hole?

The acrylic tube has an outer diameter of 63 mm, so the mounting hole or bracket opening must accommodate at least that width.

How do the compression-ring end caps seal without threading the tube, and what step do builders often miss?

The end caps use a compression ring that clamps the tube; the step often missed is fully seating the tube against the internal stop before tightening the ring to ensure a watertight seal.

Which wear items will need replacement if the seals degrade over time?

The four low-profile port caps and the two three-port end caps each include O-rings; those O-rings are the components that would need replacement if they lose elasticity.
