Kink Resistance
The braided construction ensures superior kink resistance and tight bend radius for easy installation and replacement.
EPDM Tube
The peroxide cured, calcium and zinc free, EPDM tube guarantees high purity of the cooling solutions.
Our peroxide‑cured, calcium‑ and zinc‑free EPDM hose is engineered specifically for the demands of modern liquid‑cooling systems. The high‑purity EPDM tube maintains coolant integrity by eliminating additive leaching and preventing contamination within closed‑loop water‑glycol circuits.
Peroxide curing enhances thermal and chemical stability, ensuring the hose performs reliably under continuous operation. The braided construction provides exceptional kink resistance, making installation safer and reducing mechanical stress in tight rack environments. Combined with excellent flexibility, long service life, and dependable performance at typical data‑centre coolant temperatures, this EPDM hose offers a clean, robust, and durable solution tailored for high‑density liquid‑cooling applications.
313AA ALFAGOMMA LIQUID COOLING HOSE
The Alfagomma 313AA is our recommended hose for secondary liquid‑cooling loops, offering the strength and stability required for longer pipe runs and harsher operating conditions. Its spiral‑braided reinforcement and integrated helix wire provide excellent structural integrity, helping the hose maintain shape, resist collapse, and perform reliably across extended distances. Engineered for durability and consistent coolant flow, the 313AA is ideally suited to the more demanding installation and operating environments typically found in secondary cooling circuits.

People World-Wide
Do you provide ultra‑clean hoses and assemblies for liquid‑cooling systems?
Yes. We supply ultra‑clean hoses and assemblies that are flushed and cleaned with demineralised water, including fine‑particle cleaning down to <0.25 μm where required. This supports the purity levels expected in high‑density data‑centre cooling loops and helps maintain coolant quality over long service intervals.
Are your hoses and fittings certified leak‑free?
Absolutely. Our assemblies are helium leak‑tested and built to deliver Farma‑grade quality, but without the cost typically associated with pharmaceutical‑level components. This ensures long‑term reliability and confidence in mission‑critical cooling environments.
Can you support large volumes?
Yes. Backed by the Alfagomma Group’s global manufacturing footprint, we offer strong production capacity, commonly able to provide domestic support. We also provide co‑engineering for projects that require tailored routing, assemblies, or system integration.
Are your assemblies easy to install and fully traceable?
They are. Our liquid‑cooling assemblies are designed for simple, error‑free installation, with clear identification and full traceability. We apply the same automotive‑grade processes used in our hose‑assembly production — ensuring consistency, reliability, and documentation throughout the build.
Do you offer bent tubing and orbital‑welded stainless‑steel solutions?
Yes. In addition to flexible hose assemblies, we can supply bent stainless‑steel tubing and orbital‑welded pipework, giving customers an alternative to standard OEM offerings. These solutions are ideal for secondary‑loop systems or areas requiring rigid, high‑purity pipework.
Do you supply stainless‑steel hose options as well as EPDM rubber hoses?
Yes. While our EPDM rubber hoses are widely used in both primary and secondary liquid‑cooling loops, we also offer stainless‑steel hose assemblies, including ultrasonic‑cleaned options, to support customers and contractors who prefer metal hose for its purity, durability, or regulatory alignment. We also offer welding options, offering systems with as few leak points as possible.
