    Abstract: A hose assembly, preferably a garden hose assembly, including a fabric jacketed tube that is lightweight, durable and versatile. The tube is radially expandable when pressurized by a fluid, such as water, but does not increase in length. The two layer construction of the hose assembly allows for storage in relatively compact spaces, similar flow rates, approximately one-half the weight, and improved maneuverability when compared to conventional hose constructions. In one embodiment the jacket is formed around the tube in a continuous process that welds a fabric, preferably using hot air, into the jacket. The welded joint forms a region of jacket that is preferably about twice the thickness of the rest of the jacket. This thicker region results in a stiffer section of jacket that makes the hose more controllable and consistent in use.

    Abstract: Thermoplastic elastomer compositions, in particular derived from one or more styrenic block copolymers, a relatively high molecular weight isobutylene-containing (co)polymer, and a biorenewable processing aid. The isobutylene-containing (co)polymer imparts desirable oxygen barrier performance to the composition and the biorenewable processing aid acts as a barrier synergist as well as a processing aid useful during compounding. Low oxygen permeability sealing elements can be formed from the compositions. Processes for preparing the compositions and sealing elements are disclosed.
