Marine
Silflex silicone hoses are engineered to perform in these conditions, supporting marine vessels where safety, durability, and long service life are essential.
Marine environments can create some of the harshest operating conditions for hose systems. Onboard equipment can be subject to constant vibration, fluctuating temperatures, salt-laden air, and moisture and require materials that are reliable under continuous stress. Silflex silicone hoses are engineered to perform in these conditions, supporting marine vessels where safety, durability, and long service life are essential.
Our silicone hoses are used across engine rooms, hull systems, cabins, and auxiliary onboard equipment, ensuring reliability whether the vessel is operating in calm conditions, heavy seas, or variable climates. With resistance to corrosion, oils, fuels, and marine chemicals, Silflex silicone solutions ensure reliability across long service intervals and demanding duty cycles.
Engineered for harsh marine environments
Marine systems naturally demand hose materials that will not degrade when exposed to moisture, vibration, heat, or corrosive atmospheres. Silflex silicone hoses maintain flexibility and mechanical strength even after extended exposure to saltwater, oil, and fuel vapours, making them ideal for marine applications where reliability is vital.
Every silicone hose is built to withstand tight routing paths commonly found in engine bays and hull spaces, while specialist reinforcement options ensure structural stability in high-temperature or high-vibration zones.
