Standard low pressure coolant convoluted hoses which assist with greater flexibility or misalignment of pipework. Supplied with various convolutions, dependant upon length, with or without restraining stainless steel rings. Charge Air Cooler (CAC) hoses and Turbocharger hoses are available in straight and convoluted forms, with stainless steel restraining rings for control of dilation and maintenance of axial flexibility under pressure. The benefits of convolutions can also be used where shaped or elbow hoses must be used, and the restraining stainless steel rings can be used on larger hoses to restrict the pressure being applied to the hose clamp. For more information about hose design, see our question and answer pages. Charge Air Cooler (CAC) and Turbocharger connector hoses for the automotive industry. -50ºC to +180ºC (polyester fabric) -50ºC to +250ºC (Aramid fabric) -50ºC to +305ºC (glass fabric) Pressure rating is dependant upon bore and construction. 6.5mm to 152mm in standard 1m lengths. Longer lengths and other diameters available by request. Silicone rubber reinforced with polyester or Nomex* Tape bound (Standard finish) Cellulose bound (Extra smooth finish) Coolant hose is not adversely affected by antifreeze solution or corrosion inhibitors*. For conveyance of oil or fuel, the hose can be supplied with a Fluorosilicone liner. The standard colours are blue for coolant hose, and Red Iron Oxide (RIO) for turbocharger/CAC hoses. * Rust inhibitors used without Anti-Freeze could have an adverse effect on silicone hose.
