Data center hose Data Master™

coolantEPDMhalogen-free

Overview Gates Data Master™ is a family of data center cooling hoses engineered for liquid cooling applications. The product family is developed to minimize coolant contamination, tolerate repeated thermal cycling and system pressure, offer improved flexibility for tight routing, and provide variants with reduced environmental impact for sustainable installations.

Product lines

• Data Master: Zinc-free, peroxide-cured EPDM tube material engineered for contaminant-free coolant handling; narrow ID options from 7/32" to 1" for compact installations.
• Data Master MegaFlex™: Large-ID solution using MegaFlex proprietary technology; available in sizes up to 4" ID for high-flow or high-demand cooling circuits.
• Data Master Eco: Small-diameter option (3/16", 1/4", 3/8") featuring a halogen-free, flame-resistant cover and manufacturing changes aimed at reducing CO2e emissions.

Key features & benefits

• Cleaner systems: Zinc-free, peroxide-cured EPDM tube reduces risk of coolant contamination and supports longer service intervals.
• Coolant compatibility: Formulated to be compatible with a broad range of coolants, including PG25 mixes, for closed‑loop liquid cooling architectures.
• Superior flexibility: MegaFlex proprietary constructions and optimized hose designs enable easier routing in constrained in-rack and in-row layouts.
• Flame-resistant options: Selected covers and constructions meet UL94V-0 and are tested to UL224 VW-1 where specified for electrical and rack safety requirements.
• Ozone resistance: Elastomer selections resist cover degradation in electronics environments.
• Sustainable option: Data Master Eco offers a halogen-free cover and manufacturing process adaptations claimed to reduce up to 75% CO2e in production.

Applications

• Chilled water distribution and connection lines in data centers (CRAC/CRAH units and chilled piping).
• Direct-to-chip liquid cooling for motherboards, cold plates and high-density compute nodes.
• In-row and in-rack cooling systems that require tight bends and reliable flow performance.
• Any closed‑loop low‑ to high‑flow liquid cooling architecture in data center environments.

Resources Sell sheets, family brochures and technical flyers are provided for the Data Master family, Data Master MegaFlex™ and Data Master Eco to support selection and specification. Product literature and technical documents are available for download from the manufacturer's resources.
