This specification covers the materials and performance of elastomeric turbocharger hoses for higher temperature resistance.
Material Description. Materials covered by this specification are divided into the following types:
Type A: Fluoroelastomer (FKM) lining, peroxide cured with Silicone Elastomer (VMQ) intermediate layer and cover for +180°C permanent and +200°C peak temperatures.
Type B: FKM lining, bisphenolic cure system with higher elongation, with VMQ intermediate layer and cover for +200°C permanent and +225°C peak temperatures.
Type C: FKM lining, peroxide cured with VMQ intermediate layer and cover for +200°C permanent and +225°C peak temperatures.
Type D: Fluorosilicone elastomer (FVMQ) lining with VMQ intermediate layer and cover for +180°C permanent and +200°C peak temperatures.
Type E: Drawing defined (e.g., using SAE J200 or ASTM D2000 line callout). If no type of material is indicated, material of type A is sufficient.
All hoses shall have textile reinforcement suitable to fulfill the requirements of the material and durability tests.
