Description

Our ‘Organic-Acid-Technology’ hoses are designed to resist extended life anti-freeze coolants containing sebacate or 2-ethylhexanoic acid. In this case, standard blue coolants hoses will fail to provide the necessary protection. Our OAT hoses are available in 3 different models: Silicone Bolt, EPDM+ and Silicone Bolt+. We recommend the 4-ply reinforced Silicone Bolt with a temperature range of -50°C to +215°C for gases that permeate the silicone liner and damage polyester fabrics. In case of potassium/sodium 2-ethylhexanoic acid presence in the coolant, our EPDM+ hose with a temperature range of -40°C to 150°C is an ideal choice with a special grade of EPDM reinforced with 1-ply Aramid. Silicone Bolt+ hoses are manufactured with an impermeable inner liner that withstand the harshest gases and chemicals that could otherwise permeate a silicone liner. This hose has a temperature range of -25°C to 225°C.
