White cylindrical reservoir with black knurled rings and installed pump head, 120mm tube length, matte finish

PrimoChill

PrimoChill CTR Hard Mount High Flow D5 Reservoir White POM 120mm TX Matte Black

SKU CH-R850-FSGP7

Hard-mount D5 reservoir with compression-ring seals, 120 mm tube, white POM end caps and matte-black knurled rings included

  • Compression-ring end caps seal without cutting or tapping the tube
  • 57 mm inner diameter supports high-flow D5 pump integration
  • 205 mm overall length fits 120 mm CTR tube configuration
  • White POM components with TX matte black rings for coordinated aesthetics
  • Includes three low-profile port caps and anti-vibration mounting pads

Hard-Mount D5 Reservoir

The PrimoChill CTR reservoir is built for custom-loop builders who want a rigid, hard-mounted D5 pump platform. Its compression-ring end caps seal the acrylic tube without cutting or tapping, removing the risk of cracked tube ends. The white POM pump head and three-port end cap come pre-installed, so the loop can be assembled straight from the box.

G1/4 Thread Limits

All ports use standard G1/4 threads, restricting fittings to that thread size and ruling out larger-bore or proprietary connectors. The three low-profile port caps seal unused openings but do not add extra routing options. Builders planning more than three active ports will need a different reservoir topology.

120 mm Tube Capacity

The 120 mm CTR tube with a 57 mm inner diameter holds a modest coolant volume suited to single-loop builds with one radiator and a few blocks. Longer runs, multiple radiators or high-flow pumps will exhaust the reservoir's headroom quickly, making it unsuitable for large-volume or multi-loop configurations.

Questions about this item

Should I pick the 120 mm tube length or a different size for my loop?

The kit includes a 120 mm CTR tube; choose that length if your pump-to-radiator spacing matches 120 mm, otherwise select the CTR size that fits your measured run.

What does the 205 mm overall length mean once the D5 pump is installed?

With a compatible Laing D5 or PrimoChill PWM D5 mounted, the assembly measures 205 mm end-to-end, so verify your case clearance before ordering.

Will the G 1/4 threads limit my fitting choices or flow rate?

All ports use standard G 1/4 threads, accepting any G 1/4 fitting; the 57 mm inner diameter keeps restriction low for high-flow loops.
