Gates 3/4 in. Data Master Data Center Coolant Hose

3/4-Inch EPDM Hose for High-Density Liquid Cooling

The Gates 3/4 in. Data Master Data Center Cooling Hose is a high-performance fluid transfer hose engineered to maintain the operational integrity of critical IT infrastructure. This hose is specifically designed to meet the thermal management requirements of modern data centers, where transitioning to liquid or hybrid cooling can result in up to 40% energy savings.

Gates Data Master hoses feature a proprietary metal-free, peroxide-cured EPDM tube that prevents fluid contamination and ensures long-term compatibility with deionized water-glycol mixtures like PG25. It's made with synthetic fiber braid reinforcement and a flame-resistant cover that meets UL94V-0 and UL224 VW-1 standards for fire safety in data center white spaces.

This 3/4-inch hose has a narrow profile and superior flexibility to simplify installation in complex, high-density layouts, reducing the force required to achieve tight connections in cramped server racks where space is at a premium.

• Broad Temperature Range: Maintains structural integrity from -40° F to 212° F (-40° C to 100° C)
• High-Pressure Integrity: Maximum working pressure of 300 psi (2.1 MPa) with a minimum burst rating of 1,200 psi (8.3 MPa)
• Precision Routing: 1.02-inch O.D. and a 4.1-inch (105mm) minimum bend radius for easier routing around sensitive components
• Durable Materials: The EPDM cover provides excellent ozone resistance to prevent degradation caused by proximity to high-voltage equipment
• Compatible with: Push-lock, lock-on, and crimped (GLX & SS) fittings for secure, leak-free cooling loops
