1. A method of coupling two pipes, comprising:
- placing an assembled coupling over one end of a first pipe, wherein the coupling comprises;
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 and having a concave outer diameter, wherein the gasket is comprised of two primary seals, one on each outer edge of the gasket;
sliding the coupling over the end of the first pipe so that at least a portion of the first pipe is extending beyond each edge of the gasket;
aligning a second pipe with the first pipe;
