## Abstract

The fluid line segment can have a body having an inlet, an outlet, and a gas path extending between the inlet and the outlet, a containment cavity extending between the gas path and a cavity bottom, the containment cavity in fluid communication with the gas path, a projection protruding from the cavity bottom of the containment cavity towards the gas path, an orifice defined in the projection, and an evacuation passage extending from the orifice, across the projection and leading outside the body, the evacuation passage being in fluid communication with the containment cavity and the gas path via the orifice.

## Claims

### Claim 1

A fluid line segment comprising :
a body having an inlet, an outlet, and a gas path extending between the inlet and the outlet,
a containment cavity extending between the gas path and a cavity bottom of the containment cavity, the containment cavity in fluid communication with the gas path,
a projection protruding from the cavity bottom of the containment cavity towards the gas path, an orifice defined in the projection, and
an evacuation passage extending from the orifice, across the projection and leading outside the body, the evacuation passage being in fluid communication with the containment cavity and the gas path via the orifice.

### Claim 2 (depends on 1)

The fluid line segment of claim 1 wherein the orifice is located at a tip of the projection.

### Claim 3 (depends on 1)

The fluid line segment of claim 1 wherein the containment cavity is annular around the projection.

### Claim 4 (depends on 1)

The fluid line segment of claim 1 wherein the gas path forms an elbow, the containment cavity extending downwardly from a vertex of the elbow.

### Claim 5 (depends on 1)

The fluid line segment of claim 1 wherein the containment cavity, projection and evacuation passage are formed in a component which is selectively removable from the body of the fluid line segment.

### Claim 6 (depends on 1)

The fluid line segment of claim 1 further comprising a screen extending across the gas path, downstream of the containment cavity.

### Claim 7 (depends on 1)

The fluid line segment of claim 1 wherein the gas path extends straight between the inlet and the outlet, and the containment cavity branches off transversally from the gas path.

### Claim 8 (depends on 1)

The fluid line segment of claim 1 forming of a fitting including an inlet connector at the inlet and an outlet connector at the outlet.

### Claim at position 9

9-20. (canceled)
