OCP-Standard Peroxide-Cured Zinc-Free EPDM Hoses

Overview:

OCP-standard peroxide-cured EPDM hoses are engineered to meet the demanding performance and cleanliness requirements of next-generation liquid-cooling systems. Designed specifically for use in data-center, power-electronics, and high-density computing environments, these hoses combine superior thermal stability, chemical resistance, and long-term fluid cleanliness in a flexible, serviceable construction. The peroxide-curing process ensures a cross-linked molecular structure that resists degradation, while zinc-free compounding eliminates the risk of ion leaching or coolant contamination that can compromise critical equipment.

Key Technical Advantages:

Zinc-Free EPDM Tube: Prevents metallic extractables, maintaining coolant purity and electrical isolation integrity.

Peroxide-Cured Elastomer: Offers enhanced resistance to heat aging, oxidation, and coolant chemistry compared to sulfur-cured EPDM.

Flame-Resistant Construction: Meets or exceeds UL 94 V-0 and UL 224 VW-1 standards for use in high-density electronic enclosures.

Wide Temperature Range: Typical operating range –40 °C to +120 °C (–40 °F to +248 °F), ensuring flexibility under varying thermal loads.

Ozone and Weather Resistant: Ideal for electronic-room and rooftop service where ozone exposure accelerates material fatigue.

Coolant Compatibility: Optimized for glycol-water and dielectric coolants used in direct-to-chip, immersion, and manifold distribution systems.

Data-Center Application Focus:

These hoses form the backbone of liquid-cooling distribution networks in Open Compute Project (OCP)–compliant systems. Their low-extractables formulation ensures the cleanliness required for deionized or glycol-based coolant loops feeding cold plates, CDUs, and rack manifolds. The flame-resistant cover and narrow bend radius support compact routing inside server aisles and containment zones, enabling higher rack density and serviceability. Designed for long-life performance and minimal maintenance, peroxide-cured zinc-free EPDM hoses help data-center operators achieve reliable, contamination-free thermal management while meeting OCP sustainability and interoperability standards.
