Barrier hoses are a type of air conditioning (AC) hose that is designed with an extra layer to prevent refrigerant leakage. This layer acts as a barrier against refrigerant molecules, which are small and can escape through standard rubber hoses over time. Barrier hoses are commonly used in modern automotive AC systems to comply with environmental regulations and improve system performance.key points to cover when discussing barrier hoses:
Construction: Barrier hoses are constructed with multiple layers to enhance durability and prevent refrigerant leakage.
Refrigerant Compatibility: Barrier hoses are designed to be compatible with various types of refrigerants used in automotive AC systems, including R134a, R1234yf, and others.
Performance Benefits: Using barrier hoses in AC systems improves performance by maintaining proper refrigerant levels and pressure.

Refrigerant hoses include a permeation inhibiting layer, wherein the permeation inhibiting layer is formed of mixture based upon a polyether-ester block copolymer, a polyamide-polyether block copolymer, or a blend thereof. A tie layer surrounds the permeation inhibiting layer, and the tie layer is based on a butyl rubber. A reinforcing layer surrounds the tie layer, and a cover layer is disposed adjacent the reinforcing layer. In some cases, an innermost rubber tube is disposed inwardly adjacent the permeation inhibiting layer, and the innermost rubber tube is comprised of rubbery polymer. The refrigerant hoses may further include a second tie layer surrounding the reinforcing layer, and a second spiral reinforcing layer disposed between the cover layer and the second tie layer. Furthermore, the hoses may have a permeation rate of not greater than 0.0020 g/cm/day of R-1234yf refrigerant.
