A hose includes a bisphenol A curable rubber tube layer, an optional nitrile rubber friction layer disposed over the tube layer, a reinforcement layer disposed over the tube layer or optional 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.

All rubber low sulfur and extraction PED hose

The subject invention discloses a low permeation curb pump hose comprising: (a) a tube layer, wherein the tube layer is comprised of a first nitrile rubber; (b) a barrier layer which is situated over the tube layer, wherein the barrier layer is comprised of a fluorothermoplastic; (c) a friction layer which is situated over the barrier layer, wherein the friction layer is comprised of a second nitrile rubber; (d) a reinforcement layer which is situated over the friction layer, wherein the reinforcement layer is comprised of braided steel wire, wherein the braided steel wire has a wire pack coverage of about 30 percent to about 60 percent; and (e) a cover layer which is situated over the reinforcing layer, wherein the cover layer is comprised of a chlorinated polyethylene.

Low permeation curb pump hose

A hose fitting includes a stem defining a conduit therein, a ridged axial portion, an opposing axial portion and a stem shoulder. The fitting also includes a swivel nut having threads and wrench flats, where the swivel nut defines a swivel nut end adjacent the threads, and the swivel nut is disposed on the opposing axial portion of the stem. The fitting also has a metallic wave spring washer disposed upon the stem between the stem shoulder and the swivel nut end, and a ferrule for securing a hose to the hose fitting at the ridged axial portion of the stem. In some cases, an inner fitting is disposed in the conduit at the opposing axial portion of the stem, and an inner hose may be in the conduit and attached to the inner fitting.
