Data Centre Cooling Solutions & Semi-Conductor Infrastructure
Your Premier Hose Solutions Partner for Data Centre Cooling Solutions
Liquid cooling is the future of data centres. In a rapidly growing market, the right hose is no longer a commodity — it is a critical component that determines system reliability, energy efficiency and long-term performance. At Flextech we design and manufacture bespoke flexible hose assemblies engineered specifically for liquid cooling systems. We understand that liquid cooling only works if the hose works. That is why we select and build with polymers that are not just compatible with your coolant, but precisely engineered for it. Whether you are scaling high-performance computing clusters, designing AI-ready infrastructure, or optimising thermal management in high-density environments, our tailored hose solutions help ensure uninterrupted operation and maximum uptime.
Why Flextech's Hose Assemblies for Data Centre Applications?
Strategically located along the M4 corridor, Flextech is uniquely positioned to support the investment and growth in the UKs data centre infrastructure. Europe’s largest data centre cluster is in Slough, which is home to around 35 data centres. Slough is easily accessible, sits along high-speed fibre-optic cables connecting London with Ireland and the United States, and is close enough to London to provide the City’s financial institutions with the extremely low-latency connectivity they need.

Explore our HPC hose range for Data Centres
High-Performance Computing (HPC) Series: Bespoke hose assemblies designed for thermal efficiency.
The HPC (High-Performance Computing) Series is developed to meet the needs of modern data centre infrastructures. This portfolio of hose specifications combines engineering innovation, advanced customisation, and precision industrial manufacturing, with every component designed to guarantee long-term performance and seamless integration under critical operating conditions. All HPC hoses for data centers are designed to withstand high mechanical loads while maintaining optimal flexibility, ensuring consistent performance in high-density operating environments.
EPM (EPDM Category of Rubber) Hoses: Resistance and Compatibility with Glycol-Based Fluids.
EPM (EPDM rubber category) is a heat-resistant polymer offering excellent compatibility with PG25 and other water-glycol coolant solutions. To preserve fluid purity and composition, the compound is peroxide-cured. Fungicides and bactericides added to the conveyed fluid prevent microbial growth, ensuring long-term safety and reliability.
PTFE Hoses: Chemical Inertness and Extreme Flexibility.
PTFE is a heat-resistant polymer with a very low friction coefficient (0.02), ensuring excellent fluid circulation. It offers outstanding chemical compatibility with PG25 and other water-glycol solutions and is also suitable for immersion cooling systems using dielectric fluids. Being chemically inert, PTFE prevents absorption and release of substances, maintaining fluid purity and composition.
Silicone Hoses: wide temperature range and insulating properties
Silicone offers excellent heat resistance across a wide temperature range (-60°C to +200°C / -76°F to +392°F), while maintaining flexibility. It provides excellent insulating properties, resistance to ozone and UV, and low flammability. Its low thermal conductivity ensures outstanding insulation performance. Compatible with PG25 and other glycol-water solutions. The gray silicone cover compound and hose construction are classified V-0 according to UL 94:2023.
Performance & Benefits: reliability, efficiency, and operational safety.
The hoses developed in the HPC hose range are developed to ensure reliability and operational continuity in liquid cooling systems for data centres. All hoses are designed to minimise the risk of failures and leaks, extending equipment life. Manufactured from selected materials, they guarantee thermal stability and resistance to intensive loads, reducing downtime. Our hose assemblies are designed for use with various fittings, providing maximum flexibility of integration into different systems.
Contamination Protection and Failure Risk Reduction
Polymeric compounds and chemical inertness preserve the purity and composition of the coolant, preventing contamination that could damage system components.
Energy Efficiency and Cost Optimisation
The low internal friction coefficient (especially PTFE with 0.02) ensures efficient fluid circulation, optimizing cooling performance and reducing pump energy consumption. These solutions support companies in transitioning toward more efficient infrastructures, lowering energy costs and inefficiencies associated with traditional systems.
Flame Resistance and Durability
Covers compliant with UL 94:2023 V-0 criteria provide an additional safety level in high-temperature environments, mitigating fire propagation risks. Hoses maintain high flexibility under extreme conditions, facilitating installation and routing in confined spaces while reducing mechanical stress on connections. They are tested to withstand bending cycles and vibrations typical of data centre environments. Covers are resistant to abrasion, aging, ozone, and UV, ensuring long-term durability.
Hoses for Semi-Conductor Industry
With our expertise and understanding of hose technology, we are committed to providing to and supporting semiconductor manufacturers worldwide. Our hose assemblies are designed to optimise performance, reliability, and safety in semiconductor applications.
