Reinforced to ensure that not only do they withstand greater temperatures and pressure when compared to the original Hoses, but they also look amazing in a choice of different colors.
All supplied within our coolant hoses range are manufactured with a protective inner lining, as standard, to ensure the compatibility with modern coolants. Some of the first vehicle coolants or antifreezes contained methanol, which is still found in windshield washer fluid. As these mixtures require constant replenishment due to the evaporative properties, and can increase the corrosion of aluminum, which at this time is becoming more widely used, a new coolant was developed.
This was Ethylene Glycol mixtures, though less corrosive, it still required regular attention to maintain it's antifreeze properties. More recently OAT or Organic Acid Technology coolants have been developed and used. These are normally orange in colour to differentiate them from the glycol-based coolants, which are green or yellow. OAT coolants have an extended service life of around five years use. Whilst standard silicone hoses have a high resistance to the Ethylene Glycol coolants, they can quickly deteriorate, if not protected, when OAT coolants are used. It is for this reason that our unbeatable range of Silicone Hoses for Cars include an internal lining of Fluorosilicone to protect and ensure the longevity of the product.
