Typical uses of exhaust hose include engine exhaust and vacuum and collection service, conveying, ventilating lines and protective casing for cable and tubing. They are commonly used as accessories for corrugated hose assemblies as well. Interlocked liners reduce flow velocity while interlocked armor prevents overbending near the end fittings.

The strip thickness, and thus the hose weight, can be selected to match the application depending upon the degree of rough handling and the abrasive conditions of the service. Penflex makes three different weights of exhaust hose as indicated in the following tables.

Series	Weight Designation	Strip Thickness
IE30	Light	.010″ to .012″
IE40	Mid-Weight	.015″
IE50	Standard	.018″ to. 020
