Data Center Hose

ExtremeFlex DataGuard™ for Source Line & External Feed Applications

Choosing the right data center cooling hose assembly is critical to system performance, safety, and uptime. ExtremeFlex DataGuard™ by ContiTech is a purpose-built data center liquid cooling hose engineered for external source line and feed applications. Designed specifically for modern thermal management systems, it delivers superior flexibility, UL flame-rated performance, and peroxide-cured EPDM construction to protect both coolant integrity and mission-critical equipment. We can fabricate the DataGuard hose with any crimped fitting configuration. Full hose assembly testing and tracking also available. 

If you are a mechanical contractor or OEM designing liquid cooling systems, ExtremeFlex DataGuard provides the reliability today’s data centers demand.

Why Data Centers Require Specialized Cooling Hose

Not all industrial hoses are suitable for data center liquid cooling.

Modern cooling infrastructure requires:

  • Flame-rated materials for fire safety compliance

  • Low-extractable tube compounds to protect coolant purity

  • Dimensional stability in confined routing spaces

  • Superior flexibility for tight bends and compact CDU layouts

  • Reliable crimp and clamp termination options

ExtremeFlex DataGuard is engineered specifically to meet these critical-to-quality (CTQ) requirements in data center cooling environments.

ExtremeFlex DataGuard™

A High-Performance Data Center Liquid Cooling Hose

ExtremeFlex DataGuard is designed for source line / external feed hose applications that connect CDUs to rack manifolds and facility cooling loops.

Key Features & Benefits

Peroxide-Cured EPDM Tube

  • Minimizes material extraction into cooling fluids

  • Protects sensitive IT equipment

  • Supports long-term coolant cleanliness

  • Withstands continuous thermal cycling

For OEM system designers, this means lower contamination risk and improved system longevity.
