Vena® MILTECH: High-Performance Silicone Hoses for Military Cooling Systems

Vena® MILTECH is Venair’s advanced silicone hose solution specifically engineered for engine cooling systems in military vehicles and other high-demand industrial sectors. This reinforced silicone hose line has been developed to meet the strictest technical and regulatory requirements, including MIL-STD A-A-52426 and SAE J20 standards.

Silicone Solutions for Extreme Conditions

Manufactured with high-performance VMQ silicone and four layers of textile reinforcement — either polyester or aramid fabric — Vena® MILTECH offers exceptional resistance to internal pressure, outstanding flexibility, and reliable performance under extreme temperatures and vibrations.

Its optimized formulation ensures:

· Thermal resistance up to +220 °C (peak) and down to -60 °C in extreme cold.

· High durability against mechanical fatigue and deformation caused by thermal cycles.

· Excellent resistance to ozone, humidity, oils, and solvents.

· Full compliance with MIL-STD A-A-52426 and superior properties to those required by SAE J20.

Customized Hoses and Silicone Parts for Defense Applications

Thanks to its versatility, Vena® MILTECH enables the production of straight hoses, custom silicone parts with lateral branches, integrated metal fittings, and tailor-made designs for intercoolers or glycol and water lines in military trucks, combat vehicles, and off-road defense systems.

This flexibility helps reduce the number of hose connections, minimizing the risk of leakage and enhancing safety in critical applications.

Certified Quality for International Military Projects

Vena® MILTECH has passed rigorous validation tests, maintaining stable mechanical properties under demanding conditions. Its proven reliability makes it a strategic choice for military vehicle manufacturers, system integrators, and OEMs operating in the U.S., Europe, and Asia.
