## Abstract

A fluid handling swivel joint and fluid conveyance equipment incorporating the same includes a first flanged portion, a tail portion that form a conduit. The fluid handling swivel joint also includes a body secured to the first flanged portion and at least partially surrounding the tail portion, where the body and the tail portion form a raceway. The fluid handling swivel joint further includes a primary seal positioned between the first flanged portion and the tail portion, and a secondary seal positioned between the first flanged portion and the tail portion and radially outward of the primary seal. The fluid handling swivel joint also includes a first environmental seal and a second environmental seal positioned to contact two of the first flanged portion, the tail portion, and the body to form an isolated volume around the plurality of roller elements.

## Claims

### Claim 1

a plurality of roller elements positioned within the raceway;
a primary seal positioned between the first flanged portion and the tail portion, the primary seal comprising a spring energized seal comprising a jacket that surrounds a spring, the spring being opened in a radially inwards direction such that the spring biases the jacket into contact with the first flanged portion and the tail portion;
a secondary seal positioned between the first flanged portion and the tail portion and radially outward from the primary seal;
a leak detection port having a leak detection tap positioned between the primary seal and the secondary seal and in fluid communication with the primary seal; and
a first environmental seal and a second environmental seal positioned to contact at least two of the first flanged portion, the tail portion, and the body to form an isolated volume around the plurality of roller elements.

### Claim 2 (depends on 1)

The fluid handling swivel joint of claim 1, wherein the tail portion further comprises a step extending towards and engaging the body in a circumferential orientation.

### Claim 3 (depends on 1)

### Claim 4 (depends on 1)

The fluid handling swivel joint of claim 1, wherein the first and second environmental seals are positioned between the tail portion and the body.

### Claim 5 (depends on 1)

The fluid handling swivel joint of claim 1, wherein the first environmental seal is positioned between the tail portion and the body and the second environmental seal is positioned between the first flanged portion and the body.

### Claim 6 (depends on 1)

The fluid handling swivel joint of claim 1 further comprising a second flanged portion coupled to the tail portion.

### Claim 7 (depends on 6)

The fluid handling swivel joint of claim 6 further comprising a primary static seal positioned between the second flanged portion and the tail portion and a secondary static seal positioned between the second flanged portion and the tail portion and radially outward of the primary static seal.

### Claim 8 (depends on 7)

The fluid handling swivel joint of claim 7 further comprising a leak detection port that is in fluid communication with the primary static seal and the secondary static seal.

### Claim 9 (depends on 1)
