Hose inner layer formed of ECO blended with NBR/PVC

A hose comprising:

• an inner tube comprising an alloy of NBR/PVC mixed with ECO, wherein the inner tube has a tube wall thickness of from 2 mm to 4 mm;
• a first reinforcement layer surrounding the inner tube, wherein the first reinforcement layer comprises a first yarn layer spiral wound over the inner tube in a first winding direction, and a second yarn layer spiral wound over the first yarn layer in a second winding direction opposite the first winding direction;
• a friction layer disposed over the first reinforcement layer;
• a second reinforcement layer surrounding the friction layer, wherein the second reinforcement layer comprises a third yarn layer spiral wound over the friction layer in a third winding direction, and a fourth yarn layer spiral wound over the third yarn layer in a fourth winding direction opposite the third winding direction;
• and,
• a cover layer disposed over the second reinforcement layer.

A fuel transfer hose comprising:

• an inner tube comprising an alloy of NBR/PVC mixed with ECO, wherein the inner tube has a tube wall thickness of from 2 mm to 4 mm, and wherein the NBR/PVC and ECO are mixed at a ratio of from 1:3 by weight to 3:1 by weight;
• a first reinforcement layer surrounding the inner tube;
• a friction layer disposed over the first reinforcement layer;
• a second reinforcement layer surrounding the friction layer;
• and,
• a cover layer disposed over the second reinforcement layer;
• wherein the fuel transfer hose has a burst pressure of up to 3500 psi at a temperature of −40 deg C.
