Handle the Heat Without Breaking a Sweat
Thermal demands aren’t slowing down, and today’s systems can’t afford weak links. As heat loads rise across high-performance computing, data centers, and advanced electronics, liquid cooling has moved from a nice-to-have to a necessity.

Parker liquid cooling quick disconnects are designed to perform under pressure, maintaining secure, reliable connections where temperature control matters most. They’re built to handle increasing thermal loads without adding complexity or stress to the system, helping operators manage the heat without breaking a sweat.

Why Trust Parker’s Liquid Cooling Quick Disconnect Couplings:

  • Designed for Demanding Thermal Environments: Parker liquid cooling quick disconnects are engineered to maintain secure, reliable connections as thermal loads increase, helping systems perform consistently where temperature control is critical.
  • Built for Smooth Integration: Across a range of system architectures, Parker quick disconnects are designed to connect cleanly and predictably, supporting efficient installation, service, and long-term operation without unnecessary complexity.
  • Confidence in Every Connection: With designs focused on secure engagement and dependable sealing, Parker liquid cooling quick disconnects help reduce the risk of connection issues—so operators can focus on performance, not second-guessing the interface.

Elevate System Reliability with Parker’s Liquid Cooling Quick Disconnects

Reliable liquid cooling depends on connections that perform consistently under pressure—often without being noticed at all. Parker liquid cooling quick disconnects are designed to operate quietly in the background, maintaining flow, managing heat, and supporting stable system performance as thermal demands increase.
That reliability shows up where it matters most. Secure, leak-resistant connections help keep systems clean and controlled. Efficient thermal performance supports consistent operation without unnecessary slowdowns. And as heat is managed effectively, the systems, and the data they support, remain protected.
It’s not about drawing attention to the connection. It’s about knowing it will do its job, every time.

  • Reduced pressure drop for superior energy efficiency and system performance
  • High resistance to vibrations and rotation
  • Broad selection of sealing materials compatible with temperature and fluids 
  • Manufacturing process that eliminates contamination of liquid cooling couplings
  • Global manufacturing and service capabilities

Featured Couplings from Parker's Quick Coupling Division

Parker’s liquid cooling quick disconnects reflect a long-standing commitment to reliable thermal management across a wide range of system designs. Engineered for secure connections and consistent performance, these couplings are designed to integrate smoothly into demanding environments where heat control and uptime are critical.

NSP1 Series
NSP1 Series quick disconnects are built for data center liquid cooling, with an internal flow path engineered to reduce pressure drop and improve system efficiency. Stainless-steel construction and a range of port configurations make integration easy across rack manifolds, flexible hoses, and IT equipment.  The couplings feature a push-to-connect design allowing users to connect and disconnect the products with one hand.
UQD Series
Universal Quick Disconnect (UQD) v1 and v2 couplings are OCP and NVIDIA Partner Network approved for data center liquid cooling. These clean-room assembled, helium leak-tested stainless-steel couplings connect rack manifolds, flexible hoses and IT equipment. The plugs and sockets are interoperable with OCP-approved suppliers. UQD v2 adds defined geometry and improved flow.
CDT Series
Designed for interchangeability and interoperability with OCP LQC Version 2.0.0, CDT Series is a flat-face, dry-break coupling for liquid cooling of electronics, servers and supercomputers. Its thread-to-connect design delivers low pressure drop, durability and leak protection.

UQDB Series
UQDB Series
The Universal Quick Disconnect Blind-Mate (UQDB) v1 and v2 Series are dry-break quick disconnects that are fully interchangeable with other Intel approved UQD suppliers. They offer excellent resistance to vibration and mechanical stresses and offer an advanced internal design for cooling applications. The plug features a floating element to accommodate 1mm of axial misalignment.
NSE Series
BQC Series
BQC Series quick disconnects are aligned to Open Compute Project’s PBMC (Pivoting Blind Mate Coupling) specification, specifically built for high-flow liquid cooling in high-density server systems. Developed for multi-supplier interoperability, these stainless steel, non-spill connectors are designed to manage higher flow rates for liquid-cooled infrastructure.

MQD Series
MQD Series, quick disconnects are optimized for liquid cooling applications in data centers, servers and supercomputers. Multi Quick Disconnect, MQD, is based on an Nvidia-driven interchange to accommodate in-tray, inner manifold liquid connections. Both plugs and sockets are interoperable and interchangeable with other approved MQD manufacturers.
