Description

Field of the Invention

A gasket installation guide used to aid in the installation of a rubber gasket into the joint between a female flare fitting and a service hose.

Background of the Invention

In order to properly connect a male flare fitting on a piping system to a female flare fitting of a hose, a sealing gasket or gasket is used in the female flare fitting to complete the seal. The confined space of a female flare fitting makes it difficult to insert a gasket into the opening at the bottom of the female flare fitting. Specifically, the female flare fitting frequently has a non-retractable internally threaded sleeve that protrudes above the opening into which the gasket needs to be inserted. The non-retractable sleeve obstructs the access to the opening, making it difficult to insert the gasket into the opening. The present disclosure aids in the installation of a gasket into a female flare fitting by allowing the body of the gasket installation device to be inserted into the sleeve of the female flare fitting, and having a shaft through the gasket installation device directly to the opening where the gasket is to be inserted. The sphero-conical shape of the shaft also causes the gasket to be slightly compressed prior to insertion, further simplifying the installation process. Extending the gasket slightly beyond the bottom of the gasket installation guide further aids in the alignment of the gasket with the female flare fitting. With this useful and proper positioning of the gasket in the gasket installation guide and the gasket installation guide properly inserted into the sleeve of the female flare fitting, a push rod is used to push the gasket into place in the opening of the female flare fitting. Then the gasket installation guide can then be slid out from the sleeve of the female flare fitting, to complete the gasket's insertion.

SUMMARY OF THE INVENTION

The present disclosure reveals a gasket installation guide to aid in the insertion a gasket into a female flare fitting of a hose connection as well as a method of use of the gasket installation guide. The gasket installation guide consists of a body with a tapered shaft passing though the body and a pushrod that facilitates the movement of the gasket through and out of the shaft. At the bottom end of the body, the shero-conical shaft is the same diameter as the interior diameter of the female flare fitting into which the gasket will be inserted. At the top of the body of the gasket installation guide, the diameter if the shaft is larger than the diameter of the gasket for easy insertion of the gasket into the body. The shaft is tapered towards the end that aligns with the female flare fitting to reduce the diameter of the gasket to slightly smaller than the female flare fitting into which the gasket will be inserted. When the lower portion of the body of the guide is inserted into the sleeve of the flare hose connection, the shaft aligns with the opening of the female flare fitting into which the gasket will be inserted. Once the body is positioned and the shaft is aligned, the pushrod is used to push the gasket into place. Having the gasket protrude beyond the end of the gasket installation guide further aids in the alignment of the gasket installation guide with the female flare fitting.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure reveals a gasket installation guide 1 to aid in the insertion of a gasket 100 into a female flare fitting 101 of a flare hose connector.

A female flare fitting 101 for a flare hose connector comprises a thread diameter 102, an inner diameter 103, a thread depth 104, a prospective gasket placement location 105, and a sleeve 106.

said gasket installation guide 1 comprising a body 2 and a pushrod 3. The body 2 and pushrod 3 being made from at least one of plastic, iron, steel, aluminum, copper, brass, nickel, or wood.

The body 2 consists of an upper portion 4 and a lower portion 5. The upper portion 4 comprising of an outer diameter 6, a height 7, a top 8, a lower edge 9, and a center hole 10. The outer diameter 6 of the upper portion 4 is larger than the inner diameter of the female flare fitting 101 into which the gasket installation guide 1 is to be inserted.

The lower portion 5 of the gasket installation guide 1 comprises an upper edge 12, a bottom 13, a depth 14, and an outer diameter 15. The lower portion 5 extends out from the lower edge 9 of the upper portion 4 to the bottom 13 of the lower portion 5. The outer diameter 15 matches the thread diameter 102 of the female flare fitting 101, so as to allow the lower portion 5 to be inserted into the female flare fitting 101. The depth 14 of the lower portion 5 is at least the thread depth 104 of the female flare fitting 101. There is a taper 16 between the lower edge 9 of the upper portion 4 to the upper edge 12 of the lower portion 5.

The center hole 10 is located in the center of the top 8 of the upper portion 4, consists of a shaft 11 that extends perpendicularly through the upper portion 4 and the lower portion 5 and is sphero-conical from the top 8 of the upper portion 4 to the bottom 13 of the lower portion 5. At the top 8 of the upper portion 4, the diameter 17 of the center hole 10 of the shaft 11 is larger than the inner 5 diameter 103 of the female flare fitting 101 into which the gasket 100 is to be inserted but not so large as to allow the allow the gasket 100 to rotate within the shaft 11. The shaft 11 tapers from the top 9 of the upper portion 4 to the bottom 13 of the lower portion 5 and is designed to slightly compress the gasket prior to insertion so as to make insertion into the female flare fitting 101 easier.

The pushrod 3 possesses a cylindrical shape and comprises a first end 18, a second end 19, a diameter 20, and a length 21. The diameter 20 of the pushrod 3 is such that the pushrod 3 can pass through the entire depth 14 of the shaft 11 while still pushing the gasket 100. The length 21 of the pushrod 3 is greater than the depth 14 of the shaft 11 of the body 2 so as to allow for easy operating 5 of the pushrod 3 into and through the shaft 11. The second end 19 of the pushrod may be flat 24 or a spherical dome 25.

The gasket installation guide 1 may further consist of a grip 21 on the pushrod 3, said grip 21 may include but not be limited to a thickening of the diameter of the pushrod near the first end.

The gasket installation guide 1 may further include a handle 22 near the first end 18 of the pushrod 3, said handle 22 to be in at least one of a loop or an extension.

The gasket installation guide 1 may further consist of threading 23 on the lower portion 5 of the gasket installation guide 1 so that the gasket installation guide 1 can be screwed into the female flair fitting 101.

The method of use of the gasket installation guide 1 comprising:

The step of inserting a gasket 100 into the center hole 10 in the top 8 of the gasket installation guide 1;

The step of inserting the lower portion 5 of the body 2 gasket installation guide 1, into the sleeve 106 female flare fitting 101 until the bottom 13 lower portion 5 of the gasket installation guide 1 aligns with the inner diameter 103 female flare fitting 101;

The step of depressing the second end 19 of the pushrod 3 through the shaft 11 until the gasket 100 is installed.

An optional additional step of protruding the gasket 100 beyond the bottom 13 of the lower portion 5 of the gasket installation guide 1 to aid in the alignment of the gasket installation guide 1 with the inner diameter 103 female flare fitting 101.
