PrimoChill

PrimoChill CTR Hard Mount D5 Reservoir Black POM 240mm TX Matte Black

SKU CH-6K2P-CYVST

A 240 mm hard-mount reservoir with compression-ring end caps for Leak-free D5 pump integration, G 1/4 ports and 57 mm inner diameter

  • Compression-ring end caps seal without cutting or tapping the tube
  • Hard-mount design secures Laing D5 pump variants directly to the reservoir
  • 240 mm clear acrylic tube with 57 mm inner diameter for high flow
  • Black POM end caps and TX Matte Black knurled rings resist corrosion
  • Includes three low-profile port caps, anti-vibration pads and all O-rings installed

Reservoir design and audience

The PrimoChill CTR Hard Mount reservoir uses compression-ring end caps to seal a 57 mm inner-diameter acrylic tube without cutting or tapping. The 2.5 inch outer diameter and G 1/4 threaded ports suit custom-loop builders who want a secure, leak-free reservoir that accepts a Laing D5 or PrimoChill PWM D5 pump. It is not for buyers who need an integrated pump or a reservoir with a different mounting footprint.

Bundled accessories and their effect

Three low-profile port caps, a three-port mountable end cap, a D5 pump head and three knurled mount rings come pre-installed in black POM with a TX matte black finish. Two rubber anti-vibration pads, four CTR O-rings and a pump O-ring are also included. These parts eliminate separate fitting purchases and provide vibration damping, but they do not add lighting, temperature sensors or additional port configurations beyond the three G 1/4 ports.

Capacity and headroom

The reservoir measures 325 mm overall length with a pump installed and offers a 240 mm tube section, giving a 2.25 inch internal bore for high-flow coolant volume. This size handles typical single-loop builds with one D5 pump and multiple radiators, but it will not fit cases limited to shorter reservoir lengths or builders who require dual-pump redundancy in a single body.

Questions about this item

Will the G 1/4 fitting threads need re-taping or replacement after repeated disassembly?

The G 1/4 threads are metal and designed for repeated use; the included low-profile port caps and O-rings maintain the seal without thread tape.

What limits continuous flow in a 240 mm long reservoir with 57 mm inner diameter?

The 57 mm inner diameter and 325 mm overall length set the hydraulic cross-section; flow is limited by the installed D5 pump head, not the reservoir tube.

How much heat does the Black POM pump head add during all-day operation?

The POM pump head and acrylic tube are passive; all heat comes from the D5 pump motor, which the reservoir does not amplify.
