Abstract
A diaphragm seal (101) for a cable gland (FIG. 1) has concentric inner (103) and outer (105) cylindrical seal walls connected at one end by a diaphragm (107) to define a cavity (121). The cavity (121) contains a plurality of support webs (125) that extend between the inner (103) and outer (105) seal walls. The webs (125) are provided on an exit side of the seal (101) and deform to assist insertion of the cable through the seal (101) from an entry side of the seal (101). The webs (12) resist inversion of the seal (101) when the pressure on the exit side is higher than the pressure on the entry side to create a pressure differential across the diaphragm (107).
