ABSTRACT:
A machine part (24) is provided with a resilient seal (28) having an in-use condition in which the seal (28) protrudes beyond a sealing face (32) of the machine part (24). The seal (28) has an alternative condition in which it is accommodated in a cut-out portion (52) in the sealing face (32) of the machine part (24). The arrangement can be used in an apparatus comprising a number of machine parts, a first machine part (24) being provided with the resilient seal (28) which protrudes beyond a sealing face (32) of the first machine part (24) to seal the first machine part (24) to a second machine part (30). The arrangement enables such an apparatus to be dis-assembled with reduced risk of damaging the seal or tearing it from its mounting.
