Abstract
A sleeve (19) arranged to be slidably received within a passage (9) defined in a body of a cable gland (1), the sleeve (19) arranged to receive a settable sealing material for forming a seal to a cable passing through the sleeve, wherein the sleeve (19) comprises: an annular side wall (79) extending along an axial length and having a first end and a second end; and an end wall (100) capping the first end of the annular side wall (79), in which the annular side wall (79) and the end wall (100) define a void (106) within them into which settable sealing material can be received.

A sealing apparatus for a cable gland, comprising:
- a sleeve arranged to be slidably received within a passage defined in a body of a cable gland, the sleeve arranged to receive a settable sealing material for forming a seal to a cable passing through the sleeve,
- wherein the sleeve comprises:
- an annular side wall extending along an axial length and having a first end and a second end;
- and
- an end wall capping the first end of the annular side wall,
- in which the annular side wall and the end wall define a void within them into which settable sealing material can be received;
- a hollow member for delivering settable material into the void;
- and
- a further hollow member for exhausting air from the void.
A method of installing a cable having at least one core in a cable gland comprising:
- a body having a wall defining a passage extending in an axial direction from a first end to a second end, the passage of the cable gland arranged to receive a cable;
- adjacent the first end of the cable gland body, a cable sleeve arranged to be slidably received within the passage, the sleeve arranged to receive a settable sealing material for forming a seal to the cable, wherein the sleeve comprises;
- an annular side wall extending along an axial length and having a first end and a second end;
- and an end wall capping the first end of the annular side wall, in which the annular side wall and the end wall define a void within them into which settable sealing material can be received, claim the method comprising:
- passing the cable at least partially through the cable gland;
- exposing at least one core of the cable at an end of the cable;
- placing the sleeve over each core at the end of the cable;
- puncturing the sleeve with a first hollow member and a second hollow member;
- filling the sleeve with sealable setting material by introducing the sealable setting material with the hollow member and using the first hollow member for delivering the sealable setting material into the void;
- exhausting air from the void through the second hollow member as the sealable setting material is introduced;
- and
- assembling the cable gland over the sleeve so as to seal the cable gland over the cable.
A sealing apparatus for a cable gland, comprising:
- a sleeve arranged to be received within a passage defined in a body of the cable gland, the sleeve arranged to receive a settable sealing material for forming a seal to a cable passing through the sleeve, wherein the sleeve comprises:
- a side wall extending along an axial length and having a first end and a second end;
- and
- a first end wall sealed against the first end of the side wall,
- a second end wall sealed against the second end of the side wall
- wherein the side wall, the first end wall, and the second end wall define a void within them into which settable sealing material can be received;
- a hollow member configured to deliver settable sealing material into the void;
- and
- a further hollow member configured to exhaust air from the void.
