A mechanical seal comprises an elastomeric member (3), a spring biasing member (8), a longitudinally floating first member (5), a longitudinally non-floating second member (4), a longitudinally floating third member (9) and a longitudinally floating seal face (7). The elastomeric member is in sealing engagement with the seal face and the first and second members and the spring biasing member is longitudinally pointed between the seal face and the third member. The first and second members are longitudinally restrained and rotationally coupled by male longitudinally protruding portions (12) engaging with female portions (11). |
