The Xtreme collection uses engineering developments made with Samco's Formula One customers. Xtreme offers racing parts using specially formulated Aramid fabrics to reinforce the silicone polymers, this enables them to withstand temperatures of 250°C (482°F) whilst remaining lightweight and flexible.

With a reinforced external wire, XCAC hoses offer greater resistance to profile changes and improved flexibility for more demanding requirements, with the ability to absorb greater levels of engine vibration.
