A hollow first gland part has a counterbore at one end to receive an end portion of a hollow second gland part that is axially located relative to the first gland part. A seal assembly is connected to the end portion of the second gland part for sealing engagement with a cable extending through the first and second gland parts. The seal assembly includes a diaphragm extending inwardly from an outer sleeve mounted on the end portion of the second gland part and an annular backplate for supporting the diaphragm. The diaphragm and backplate are both convergent away from the end portion of the second gland part so as to maintain sealing engagement of the diaphragm when a higher pressure exists on the side of the diaphragm remote from the end portion of the second gland part.

A cable gland comprising: a hollow first gland part; a hollow second gland part, said first and second gland parts being axially located relative to each other when the gland is assembled with a first end portion of said second gland part received in a receiving end of said first gland part, said first end portion having an axially disposed outer surface and a radially disposed end surface; and sealing means connected to said first end portion of said second gland part for sealing around a cable extending through said first and second gland parts, said sealing means including a seal and a seal support, said seal having an axially disposed outer sleeve mounted on said outer surface of said first end portion of said second gland part, and a diaphragm extending inwardly from said outer sleeve with said diaphragm converging away from said end surface of said first end portion of said second gland part for engagement with the cable; wherein said seal support is arranged in axially located relationship to said end surface of said first end portion of said second gland part and converges away from said end surface of said first end portion of said second gland part to support said diaphragm of said seal for maintaining engagement of said diaphragm with the cable when said diaphragm is subjected to a higher pressure on that side remote from said end surface of said first end portion of said second gland part.
