A mechanical seal comprises an elastomeric member (2), a spring biasing means (7), a longitudinally non-floating first member (4), a longitudinally floating second member (5) and a longitudinally floating seal face (6). The elastomeric member is in sealing engagement with the seal face and the first and second members. The spring biasing means is longitudinally positioned between the seal face and the second member. One of the first and second members is provided with at least one longitudinally protruding male portion (12) and the other of said first and second members is provided with a corresponding female portion (13) into which the male portion is positively engageable so as to restrict the relative longitudinal movement between the members. |
