120 mm hard-mount reservoir

The PrimoChill CTR Hard Mount Reservoir is a 120 mm compression-tube reservoir built for custom liquid-cooling loops. Its laser-cut acrylic tube and G 1/4 threads suit modders who want a clean, rigid reservoir without cutting or tapping the tube ends.

Two multi-port end caps included

The package supplies two three-port mountable end caps plus four low-profile port caps with O-rings. These parts let builders route coolant through multiple paths and seal unused ports without extra fittings.

158 mm overall length with 38 mm end-cap allowance

The reservoir measures 158 mm long once the end caps are fitted, adding 38 mm to the nominal 120 mm tube length. Builders must verify that their case or mounting bracket can accommodate this total length.

Questions about this item

What O-rings or seals will need replacing on this 120 mm CTR reservoir?

Each end cap uses a compression-ring O-ring that seals against the 57 mm inner-diameter acrylic tube; the four low-profile port caps also have O-rings. All are standard G 1/4 sizes available from any water-cooling supplier.

Will the 158 mm overall length fit in my case’s 120 mm fan mount?

The reservoir body is 120 mm, but the two end caps add 38 mm total, making the assembly 158 mm long. Measure the clear distance from the fan-mount face to the nearest obstruction before ordering.

Does the white POM material warp or leak when the loop runs hot all day?

The white POM end caps and laser-cut acrylic tube are rated for continuous liquid-cooling temperatures well above typical loop temps; the compression-ring design seals without stressing the tube, so heat-related warping or leaks are not expected.
