Description / Abstract:
This specification covers the materials and performance of turbo charger hoses either in four (4) layer extruded constructions or in wrapped elastomeric constructions for higher temperature resistance.
Material Description. Materials covered by this specification are divided into the following types: "continuous and excursion". Temperature limits are defined by the Vehicle Technical Specifications (VTS).
Type A: Fluoroelastomer (FKM) lining, peroxide cured with Silicone Elastomer (VMQ) intermediate layer and cover for +180 °C continuous and +200 °C excursion.
Type B: FKM lining, bisphenolic cure system with higher elongation, with VMQ intermediate layer and cover for +200 °C continuous and +225 °C excursion.
Type C: FKM lining, peroxide cured with VMQ intermediate layer and cover for +200 °C continuous and +225 °C excursion.
Type D: Fluorosilicone elastomer (FVMQ) lining with VMQ intermediate layer and cover for +180 °C continuous and +200 °C excursion.
Type E: Drawing defined (e.g., using SAE J200 or ASTM D2000 line callout).
Type F: FKM lining, peroxide cured with better dynamic properties, intermediate layer and cover of VMQ for +200 °C continuous and +225 °C excursion. This material is resistant to exhaust gas and can be used for turbo charger systems with Exhaust Gas Recirculation.
Type G: FVMQ or FKM lining with wrapped construction of reinforcement embedded in VMQ for +200 °C continuous and +225 °C excursion. Lining shall be specified selecting one (1) of Type B to Type F.
Type H: FKM lining, peroxide cured with better dynamic properties for +225 °C continuous and +250 °C excursion; intermediate layer and cover of VMQ for +210 °C continuous and +250 °C excursion. This material is resistant to exhaust gas and can be used for turbo charger systems with Exhaust Gas Recirculation. For this specification, if no type is defined, the type required by default is Type A.
All extruded hoses shall have textile reinforcement between the intermediate and cover layers that is suitable to fulfill the requirements of the material and durability tests.
Symbols. Not applicable.
Applicability. Turbo Charger Hoses.
