Abstract
An adaptive seal for a cable gland including a body including a compression portion defining a distal surface and an insertion portion defining a proximal surface, the compression portion having an outer diameter greater than an outer diameter of the insertion portion, a plurality of insertion apertures in the proximal surface, a plurality of tubes extending from the distal surface, each having a closed end and each at least partially tapering in diameter from the distal end of the body to the closed end, and a plurality of channels, each defined between one of the insertion apertures of the body and one of the closed ends of a respective one of the tubes, wherein the body and the plurality of tubes are integrally formed a single piece of elastic material.

An adaptive seal for a cable gland, comprising:
- a body having a proximal surface and a distal surface;
- an insertion aperture in the proximal surface of the body;
- a tube formed integrally with and extending from the distal surface of the body, the tube having a distal end, wherein the tube at least partially tapers in diameter from the distal surface of the body to the distal end, and wherein the distal end of the tube is closed and adapted to be opened by cutting off the distal end;
- and
- a channel defined between the insertion aperture of the body and the distal end of the tube, the channel having an inner diameter with a proximal inner diameter at the insertion aperture and the distal surface of the body, and a distal inner diameter at the distal end of the tube, the proximal inner diameter being greater than the distal inner diameter,
- wherein the inner diameter of the channel at least partially tapers from the distal surface of the body to the distal end of the tube, the tube and the channel configured such that cutting off the distal end at a first distance from the distal surface of the body creates a first opening and cutting off the distal end at a second distance from the distance surface creates a second opening, the second opening having a smaller diameter than the first opening.
An adaptive seal for a cable gland, comprising:
- a body including a compression portion defining a distal surface and an insertion portion defining a proximal surface, the compression portion having an outer diameter greater than an outer diameter of the insertion portion;
- a plurality of insertion apertures in the proximal surface;
- a plurality of tubes extending from the distal surface, each having a closed end and each at least partially tapering in diameter from the distal end of the body to the closed end;
- and
- a plurality of channels, each defined between one of the insertion apertures of the body and one of the closed ends of a respective one of the tubes;
- wherein the body and the plurality of tubes are integrally formed as a single piece of elastic material,
- wherein the plurality of channels at least partially taper in inner diameter from the distal surface of the body to the distal end, the tubes and the channels configured such that cutting off the distal end at a first distance from the distal surface of the body creates a first opening and cutting off the distal end at a second distance from the distance surface creates a second opening, the second opening having a smaller diameter than the first opening.
A cable gland, comprising:
- an entry component;
- a backnut threadably engaged to the entry component;
- and
- a seal at least partially within the entry component, the seal including a body having a proximal surface and a distal surface, an insertion aperture in the proximal surface of the body, a tube extending from the distal surface of the body and having a closed end, and a channel defined between the insertion aperture of the body and the closed end of the tube,
- wherein the tube and the channel at least partially taper in diameter from the distal surface of the body to the distal end, the tube and the channel configured such that cutting off the distal end at a first distance from the distal surface of the body creates a first opening and cutting off the distal end at a second distance from the distance surface creates a second opening, the second opening having a smaller diameter than the first opening.
