COMPOSITE FUEL AND VAPOR TUBE HAVING INCREASED HEAT RESISTANCE

摘要

The invention provides a composite fuel and vapor tube having increased heat resistance with a composite wall which in the example is described as having a relatively thin nylon liner (1), a metal strip (2) wrapped about the liner (1) and having a longitudinal seam (4) the tube being encased within a polyethylene jacket (5). The line thus formed has increased resistance to heat, abrasion and various fuels, is bendable and is capable of maintaining its shape after bending or forming operations.
