Gates 1 in. Data Master Data Center Coolant Hose

High-Efficiency 1-Inch EPDM Hose for Scalable Data Center Liquid Cooling

The Gates 1 in. Data Master Data Center Cooling Hose is a high-performance fluid transfer hose engineered to meet the thermal management needs of modern, high-density IT environments. This 1-inch hose is specifically designed for efficient coolant circulation, helping data centers transition to liquid or hybrid cooling methods that can save up to 40% in cooling energy.

Featuring a metals-free, peroxide-cured EPDM tube, the Data Master hose prevents fluid contamination and ensures best-in-class compatibility with deionized water-glycol mixtures such as PG25. Its synthetic fiber braid reinforcement and flame-resistant EPDM cover (which meets UL94V-0 and UL224 VW-1 standards) provide a reliable, non-combustible barrier for critical infrastructure.

Designed for complex routing in tight server racks, this hose has a slim profile and superior flexibility to simplify installation in space-constrained layouts. The 1-inch model supports high-capacity flow along with the durability required to withstand mechanical stress and ozone-induced cover degradation from high-voltage electronics.

• Broad Temperature Range: Maintains structural integrity from -40° F to 212° F (-40° C to 100° C)
• High-Pressure Integrity: Rated for a maximum working pressure of 300 psi (2.1 MPa) and a minimum burst pressure of 1,200 psi (8.3 MPa)
• Flexible Precision: 1.33-inch O.D. and minimum bend radius of 5.3 inches (135mm) for easy routing
• Versatile: Ideal for use in chilled water systems, direct-to-chip cooling, and in-rack/in-row cooling configurations
