Abstract

A plug for closing a hose connector termination includes a hollow cylindrical body closed by a rounded end portion and open at the opposite end. The plug comprises tensioned fibrous material that extends in a continuous manner across the width of the rounded end and to the sides of the body.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A combination of a plug and hose connector termination, comprising:
a plug having a hollow cylindrical body closed by a rounded end portion and open at the opposite end, wherein the cylindrical body and rounded end portion are continuously joined, wherein the plug comprises tensioned fibrous material that extends in a continuous manner from one side of the cylindrical body in a lengthwise manner along the body, then across the width of the rounded end, and then to an opposite side of the cylindrical body in a lengthwise manner along the body; and
a hose connector termination, wherein the plug is placed over the connector termination and the hollow cylindrical body fits juxtaposed outside on the hose connector termination and seals the connector termination.

2. The combination of claim 1 , wherein the fibrous material comprises a plurality of discrete filaments.

3. The combination of claim 1 , wherein the fibrous material comprises a mesh.

4. The combination of claim 1 , wherein the plug comprises more than one layer, each layer having tensioned fibrous material and resin.

5. The combination of claim 1 , wherein the plug comprises at least one layer having a cured resin, and further comprises the fibrous material within the resin.

6. The combination of claim 5 , wherein the plug comprises more than one layer of cured resin and fibrous material.

7. The combination of claim 1 , wherein the plug is made from an elastomer.

8. The combination of claim 7 , wherein the elastomer is silicone rubber, butyl rubber, ethylene propylene rubber, ethylene propylene diene rubber, polyisoprene rubber, polybutadiene rubber, or nitrile rubber.
