Abstract

A gas fitting comprises an integral tubular connection member, one end of which is adapted to engage a first conduit and a second opposite end of which is fixed fastly to a second conduit extending therefrom.

Description

ABSTRACT (Designate Figure 1) A gas fitting comprises an integral tubular connection member, one end of which is adapted to engage a first conduit and a second opposite end of which is fixed fastly to a second conduit extending therefrom.

It is a problem when installing gas supplies, that connections must be made between different types of gas conduit such as plastics hosing or copper pipe. For safety reasons, it is desirable to have as few intermediate connections as possible between respective conduits.

According to the present invention there is provided a gas fitting comprising an integral tubular connection member, one end of which is adapted to engage a first conduit and a second opposite end of which is fixed fastly to a second conduit extending therefrom.

An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: ic you2// - 2 Figure 1 is a perspective view of a gas fitting according to the invention; .

Figure 2 is a cross-sectional view along a longitudinal plane of the gas fitting of Figure 1.

Referring now to the drawings, there is shown a gas fitting generally indicated at 10 according to the invention. The gas fitting 10 comprises a tubular connection member 11 having a first end 13 which is adapted to be fixedly fitted into a plastics hosing (not shown) and a second opposite end 12 which is adapted to engage a pipe 14. A mid-portion 30 of the connection member 11 is hexagonal shaped so that the connection member 11 may be engaged by a spanner.

The pipe 14 shown is commonly known as a 'hockey stick’, and is provided at one end 16 with a tubular stop fixture 18 and nut 21 for connection of the end 16 of the pipe 14 to further conduits (not shown).

A shoulder 19 is provided on the internal surface of the second end 12 of the connection member 11, so that when the pipe 14 is inserted into the connection member 11, it abuts against the shoulder 19. When in position the pipe 14 is soldered into the connection member 11. The internal diameter 40 of the pipe 14 and the smaller internal diameter of the connection member 11 are equal so as to provide a cylindrical conduit of constant internal diameter offering minimum resistance to gas flow.

In use the first end 13 of the connection member 11 is push fitted into a plastics hosing (not shown). The external surface of the first end 13 is provided with annular ribs 28,29 to ensure positive IE 930277 - 3 engagement with the internal surface of the plastics hosing. A plastics annular ring 27 is pushed over the succession of annular ribs 28,29 to lie in a recessed section 31 between the mid-portion 30 of the connection member 11 and the raised rib 28.

In the case of when the plastics hosing is enclosed in a housing (not shown), the connection member 11 is pushed through an aperture in the housing so that an annular face of the ring 27 engages the internal periphery of the aperture. A horseshoe clip 26 is then pushed over the connection member 11 on the other side of the aperture so that the connection member 11 is held in a stable position relative to the housing. it 930277 - 4 CLAIMS:

Claims

1. A gas fitting comprising an integral tubular connection member, one end of which is adapted to engage 5 a first conduit and a second opposite end of which is fixed fastly to a second conduit extending therefrom.

2. A gas fitting as claimed in claim 1 wherein the first conduit is a plastics hosing.

3. A gas fitting as claimed in claim 1 or claim 2 wherein the second fitting is a tubular pipe.

4. A gas fitting as claimed in claims 1,2 or 3 wherein 15 a mid-portion of the connection member is hexagonal shaped.

5. A gas fitting substantially as hereinbefore described with reference to the accompanying drawings. F. R. KELLY & CO., Agents for the Applicants IE 930277 1/2 Ο c
