A coupler assembly (10) and method of manufacture (10) for use with pipe comprising a unitary annular body (20) forming first and second cylindrical openings for surrounding a pipe or piping sections to facilitate forming a fluid-tight seal therein. The unitary annular body (20) comprises a medial portion (64) formed from a first material having a first durometer and first and second lateral portions (56, 58) integrally connected to opposite ends of the medial portion (64). The first and second lateral portions (56, 58) are made from a second material having a second durometer relatively higher than the first durometer of the first material. The coupler assembly (10) further comprises at least one clamping assembly (26) surrounding the unitary annular body member (20) adapted for compressing the coupler assembly (10) into a fluid-tight seal.
