Custom silicone radiator hoses

SIC Hungary offers an extensive range of silicone coolant hoses in different sizes, shapes and colors. In addition to our custom coolant hoses with unique shapes and coloring we also produce standard blue Silicone/Polyester hoses that perfectly meet the criteria of SAE J20 R1 Class A. Depending on the specific pressure requirements of industrial environments our hoses’ thickness can be increased or decreased by changing the number of Polyester fabric layers in the hose. Our hoses have been intensively tested for 6 years by Erik Hugyecz professional motocross racer both in European and Hungarian Championships. He won the Hungarian championship two times. SIC chose motocross industry for testing because it has the highest RPM ranges, high engine heat and very intense movement of parts. This was an important part of our research and development cycle.

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.

Several industries require flexible yet strong spiral silicone hoses. Bending radius increases exceedingly when our high-quality spiral hoses are reinforced with a 1,2 mm thick metal fiber, making hoses flexible – even up to 160 degrees – and super-strong at the same time.

Our high-end turbo hoses are made of FKM fluorocarbon or FVMQ fluoro-silicone transferring high-pressure air. We have various automotive companies among our clientele using SIC’s strong and pressure-resistant silicone turbo hoses for decades.
