A coupling member for use in a fluid coupling, the coupling member comprising:
- a removable seal in a seal cavity defining a generally square shaped cross-section including an upper face, a circumferential face and a lower face, the removable seal comprising an upper portion, and a lower portion including a first part including an external ledge that extends perpendicularly away from the upper portion and generally parallel to the upper face defined by the seal cavity, the external ledge being configured, during use of the coupling member, to contact against the upper face defined by the seal cavity of the first coupling member, and a second part including a generally downwardly extending vane, wherein a length of the vane tapers away from the first part of the lower portion of the removable seal and terminates at a tip.
A coupling member for a fluid coupling fitted with a seal comprising:
- an upper portion;
- and
- a lower portion including:
- a first part including an external ledge that extends away from the upper portion and which is configured, during use to contact against an upper face defined by a seal cavity defining a generally square shaped cross-section including the upper face, a circumferential face and a lower face, and
- a second part.
A fluid coupling comprising:
- two coupling members each defining a seal cavity defining a generally square shaped cross-section including an upper face, a circumferential face and a lower face, and
- a seal including:
- an upper portion, and
- a lower portion including:
- a first part including an external ledge that extends away from the upper portion and which is configured, during use of one of the coupling members, to contact against the upper face defined by the seal cavity of that coupling member, and
- a second part.
