Model A Seal Kit
Replacement seal and 'O' ring for the leakless pack nut. The leakless style pack nut is an older style that was machined on the exposed portion to accept a modern lip type seal. The square O-ring in the kit slid over the threads of the rear bushing assembly and then the pack nut sandwiched the O-ring between the pump casting and the pack nut. This seal kit will not fit in a standard style pack nut.
