240 mm Hard-Mount Reservoir

The PrimoChill CTR Phase II is a 240 mm compression-tube reservoir machined from laser-cut acrylic with POM end caps in a matte black finish. It uses compression-ring seals to create a watertight joint without cutting or tapping the tube, reducing stress that can cause cracking. G 1/4 threads accept standard water-cooling fittings. The package includes four low-profile port caps with O-rings and two three-port mountable end caps.

Modders seeking tool-free tube sealing

Builders who want a rigid reservoir that locks acrylic tubing in place without threading or adhesive will appreciate the compression-ring design. The 57 mm inner diameter and 63 mm outer diameter suit common hard-tube loops. Users who prefer flexible tubing, need a pump-reservoir combo, or require a shorter reservoir than the 278 mm overall length should consider other formats.

Fits custom loops with G 1/4 fittings

The reservoir mounts directly to the case using the supplied three-port end caps, adding 38 mm to the tube length for a total of 278 mm. Standard G 1/4 ports simplify plumbing with off-the-shelf fittings. Four low-profile caps seal unused ports cleanly. The acrylic tube and POM caps resist common coolants, leaving loop layout and pump choice entirely to the builder.

Questions about this item

Which G 1/4 fittings and acrylic tubing with a 57 mm inner diameter do I need to complete the loop?

The reservoir accepts standard G 1/4 threaded fittings and is designed for 57 mm ID acrylic tubes; you must supply both to connect it to your cooling loop.

Will the 278 mm overall length and 63 mm outer diameter fit alongside my existing 120 mm radiator and pump?

At 278 mm long and 63 mm wide the cylinder needs a straight vertical clearance of that size; measure your case interior to confirm it clears the radiator and pump you plan to keep.

How can I verify the compression-ring end caps are sealing correctly after assembly?

Fill the loop slowly, watch the two 3-port end caps and four low-profile port caps for any drips, then run the pump — steady fluid level and no leaks mean the seals are working.
