Patent Images
1. A coupling for joining a first pipe and a second pipe, the coupling comprising:
- an upper housing;
a lower housing;
at least one fastening device coupling the upper housing to the lower housing; and
a gasket positioned within the upper and lower housings, the gasket including two primary seals, each primary seal formed on an outer edge of the gasket,the coupling adapted to slide over the first pipe such that the at least a portion of the first pipe extends axially beyond each outer edge of the gasket while the coupling remains in an assembled state, the coupling further adapted to join and seal the first pipe and the second pipe while the coupling remains in an assembled state.
