An improved Type C air conditioning hose is provided that meets or exceeds SAE J2064 and J3062 requirements, offers good flexibility and fracture resistance, and exhibits improved permeation ratings for refrigerants including R134a and R1234yf. The multilayer type C barrier air conditioning hose includes an inner elastomeric tube layer capable of direct bonding to plastic without an intervening adhesive. The inner elastomeric layer is prepared from a first elastomeric composition comprising a blend of an ethylene propylene diene terpolymer rubber (EPDM) and a chloroprene rubber (CR), phenylenedimaleimide, and a maleated compound.

Low permeation type C air conditioning hose

Low permeation fuel hose is provided comprising an outer cover layer prepared from a composition comprising a polyvinyl chloride (PVC), a thermoplastic copolyester elastomer and, optionally, a thermoplastic polyurethane (TPU), wherein the hose exhibits improved low and high temperature performance compared to conventional fuel hoses having an outer layer consisting of industrial grade PVC.

Low permeation fuel hose

A fuel hose is provided for use in diesel fuel, biodiesel fuel, gasoline, crude oil, lubricating oil and synthetic oil applications. The hose comprises an HNBR tube layer, a reinforcement layer and a rubber cover layer to improve ease and cost of manufacture.
