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.
