PrimoChill CTR Hard Mount D5 Reservoir 360mm Black POM TX Matte Black

SKU CH-XCV6-4GH9P

A 360 mm hard-mount reservoir with compression-ring end caps that seal a 57 mm inner-diameter acrylic tube without cutting or tapping, includes a D5 pump head and G 1/4 ports.

  • Compression-ring end caps seal without cutting tube
  • 57 mm inner diameter supports high-flow D5 pump
  • 360 mm reservoir length fits tall-case builds
  • Black POM construction resists cracking under compression
  • Includes three low-profile port caps and anti-vibration pads

What this is

The PrimoChill CTR Hard Mount reservoir is a 360 mm acrylic tube designed for custom liquid-cooling loops. It uses compression-ring end caps that seal without cutting or tapping the tube, reducing stress on the acrylic. A D5 pump head and three-port mountable end cap come pre-installed. The reservoir accepts G 1/4 fittings and compatible Laing D5 or PrimoChill PWM D5 pumps, which are sold separately.

Who it suits

Builders who want a rigid, high-flow reservoir with a matte black POM finish and tool-free tube sealing will appreciate the CTR system. It suits loops that can accommodate a 445 mm overall length once the pump is mounted. Buyers needing a pump included, a different tube diameter, or a shorter reservoir for compact cases should look elsewhere.

Deciding specification

The inner diameter is 57 mm (2.25 in) and the outer diameter is 63 mm (2.5 in), so the tube fits PrimoChill CTR compression rings and standard G 1/4 fittings. Verify that your loop design has clearance for the 445 mm installed length and that you will supply a compatible D5 pump variant.

Questions about this item

Does the box include a D5 pump or only the reservoir and mounting hardware?

The package contains the reservoir body, a pre-installed D5 pump head, three low-profile port caps with O-rings, three knurled mount rings, two rubber anti-vibration pads and all sealing O-rings. A Laing D5 or PrimoChill PWM D5 pump must be purchased separately.

What does the 360 mm designation refer to on this CTR reservoir?

The 360 mm figure indicates the nominal tube length class; the actual outer diameter is 63 mm (2.5 inches) and the overall length with a pump installed measures 445 mm.

How does the 57 mm inner diameter affect flow when a D5 pump is fitted?

The 57 mm bore matches standard D5 pump tops, providing an unobstructed high-flow path that supports the pump's rated throughput without restriction.
