Each flange (4,6) includes a bore and a counterbore. The seal comprises a compression sleeve seal (12) having a length that is greater than a counterbore (8) -to-counterbore length of two flanges (4,6) ; a fastener (16) configured to extend through the compression sleeve seal (12); and a nut (14) threadable on each end of the fastener (16). The compression sleeve seal (12) is compressible between each flange (4,6) and each nut (14) to create a first seal and is radially extensible to create a second seal against each bore (10).</p> |
