Problems solved by technology

[0008] The development of fuel hoses that do not increase the sulfur and / or gum content of the fuel conveyed therein has proven difficult
For example, dispensing fuel through most existing commercially available hoses results in unacceptably high sulfur levels in the fuel, for example, reaching sulfur in the range of 50 ppm to 100 ppm after a period of rest (eg, not used overnight), and 300 mg / 100ml or even more than 1000mg / 100ml of unwashed gum extract
[0009] Difficult to meet today's standards as fuel hoses must possess a range of physical and chemical properties that cannot be compromised

Abstract

A hose includes a fluorothermoplastic tube layer, a nitrile rubber friction layer disposed over the tube layer, a reinforcement layer disposed over the friction layer, the reinforcement layer comprising braided steel wire, and a cover layer disposed over the reinforcing layer, where the cover layer may comprise chlorinated polyethylene. The tube layer defines a lumen in the hose, and a vapor return line may further be disposed within the lumen of the hose. Hose embodiments of the disclosure may be useful in fueling applications for vehicles using fuels such as gasoline, gasohol, diesel, biodiesel, avgas or jet fuel.

Description

[0001] Related application information [0002] This patent document claims priority to US Provisional Patent Application No. 62 / 094174, filed December 19, 2014, which is incorporated herein in its entirety. technical field [0003] The present disclosure generally relates to hoses suitable for use in conveying fuels such as gasoline, gasoline, diesel, biodiesel, aviation gasoline, and jet fuel. These hoses are especially valuable for use with conventional and vapor recovery fuel dispensing pumps such as those used to refuel cars, trucks, agricultural equipment, locomotives, aircraft, etc. Background technique [0004] This section provides background information to facilitate a better understanding of various aspects of the disclosure. It should be understood that the descriptions in this section of the document are to be read in this light and not as descriptions of prior art. [0005] There are various performance requirements for hoses used in fuel pumps such as those ...
