FD83 series Full flow dual interlocking coupling

An industry standard, our stainless steel FD83 has been supporting data center liquid cooling reliably for decades.

• Interlock design ensures parts cannot be disconnected while liquid is flowing

• Multiple end connection configurations, including angled hose barbs are available

• Ball valve for full flow and minimal pressure drop

Light-weight, durable engineered composite design available 2021. Offers same operating performance and is interchangeable with current design.

Eaton FD83 Coupling Aninmation


Blindmate QD Self-centering double acting coupling

Made to allow easy, trouble-free connections of server blades this is the smallest size connector in our offering. Made to a standard interchange but with the design integrity and quality that Eaton is known for.

• Very low variability in valve centering to ensure proper alignment

• Force to connect below specifications requirement

• One connector mounts to rack while other installed on blade

• Designed to work directly with hose and tubing


MLDB series Flat face/dry break Coupling

Eaton’s MLDB series stainless steel coupling is a flat face/dry break coupling ideal for liquid cooling applications. Designed with a focus on high flow rate and low pressure drops this coupling is perfect for smaller connection lines.

• Safety sleeve lock prevents accidental disconnections

• Push to connect with double shut-off valving


ADB series Flat face/dry break Couplings

Eaton’s flat face aluminum (ADB) coupling is a lightweight, strong dry break coupling featuring Eaton’s proprietary profile and alignment features providing easy connection.

• Ideal for smaller supply lines when superior performance is needed compared to plastic couplings

• Optional color anodized option to aid in connection matching

Thermoformed solution

Eaton’s thermoformed hose assembly solution provides the optimum solution for liquid cooling applications. This solution removes leak points common with other systems and provides excellent flow performance giving your data center the most compact and cleanest routing.

H201 Eaton easy couple hose

Hose ideal for liquid cooling supply lines when leak free connections around electronics are required. H201 provides excellent fitting retention with no crimping required when matched with qualified Eaton’s barb connectors.


FC332 AQP High temperature Socketless  hose

Textile braid reinforcement with higher temperature performance when compared to H201. To be used in critical thermal applications.


GH109 Flexible, lightweight EPDM hose

GH109 EPDM hose is designed specifically for coolant applications. The highly engineered EPDM tube compound offers excellent fluid resistance with coolants. It is also extremely flexible making assemblies and easy to install in tight routings.

Rest easy knowing your cooling liquid will continue to provide top performance instead of risk.


EH001 Flexible flame and abrasion resistant hose

Eaton’s industrial cooling hose is designed for lower pressure systems, and is ideal for larger supply lines, in data cooling applications. Nitrile inner tube provides excellent cooling fluid compatibility and performance. Qualified hose assembly with the FD83 coupling. UL 94 V2 flame rating.



4245 Eclipse Formable thermal tubing

Nylon-based tubing that is ideal for cooling applications and can be formed to match a specific routing. Eaton’s thermal tubing has superior abrasion resistance, easy to cut, and has excellent flexibility when used in non-formed routings. Specific hose routings can use different colors for easy identification. UL 94 HB flame rating.
