Product Description

Quick Disconnect Coupling for Liquid Cooling Solutions


The UQD Series is the universal quick disconnect coupling in our liquid cooling family. One body design covers 2, 4, 6 and 8 inch equivalents, so a facility can standardise on a single coupling type across its loops instead of stocking a different part for every line size, and it is rated as universal for both load and working medium.

The body is built on a SUS304 or SUS316 stainless base, which keeps the wetted surfaces corrosion-resistant in glycol, aqueous solution and deionized water. Both halves seal themselves the moment they separate, so a loop can be opened and re-made without draining it; seals are available in EPDM (-45°C to 150°C with ethylene glycol), FKM and NBR, and the interface can be thread, flange, barb or union.

CGQ Series › Quick Connector Light Load Glycol, Aqueous Solution Direct steel ball fastening for rapid manual operation.
CGB Series › Blind Connection Light Load Glycol, Aqueous Solution Locked by external structure (e.g., chassis), no internal fastening.
UQD Series › Universal Universal Various Available in 2/4/6/8 inch equivalents, SUS304/316 Base.

Product Features

Universal quick disconnect coupling for 2/4/6/8 inch lines

One Universal Body for 2/4/6/8 Inch Lines

The UQD Series is the universal member of the family: the same body design is offered in 2, 4, 6 and 8 inch equivalents, so a single coupling type can be specified across a whole facility instead of matching a different part to every line size. Both halves are self-sealing, so a loop can be opened and re-made without dumping its coolant.


SUS304 and SUS316 Stainless Base

The UQD Series is built on a SUS304 or SUS316 stainless base, which keeps the wetted surfaces corrosion-resistant in glycol, aqueous solution and deionized water loops. Seal options are EPDM (rated -45°C to 150°C with ethylene glycol), FKM for aggressive media and NBR, and the interfaces can be supplied as internal thread, external thread, flange, pagoda (barb) or union.

FAQ


1. What is the difference between Self-Fastening and Blind Connection?
Self-Fastening (e.g., CGN/CGQ) uses an internal steel ball mechanism to lock the connection manually. Blind Connection (e.g., CGB) has no internal lock and relies on external force (like sliding a server into a chassis) to maintain connection, enabling automatic docking.
2. Which sealing material should I choose for data center cooling?
For standard data center coolants like Ethylene Glycol (EG) or Deionized Water, EPDM is recommended due to its excellent compatibility and temperature range (-45°C to 150°C).
3. Do you support customized interfaces?
Yes, we offer a variety of interface modes including Internal Thread, External Thread, Flange, Pagoda (Barb), and Union connectors to match your existing piping infrastructure.
4. What sizes and base materials does the UQD Series cover?
The UQD Series is offered in 2, 4, 6 and 8 inch equivalents, which makes it the option to specify when one coupling type has to serve several line sizes in the same facility. The base material is SUS304 or SUS316 stainless, and the seal package (EPDM, FKM or NBR) is chosen to match the coolant actually in the loop.
