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.

1. A coupler assembly for use with pipe comprising: a unitary annular body 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 comprising a medial portion and first and second lateral portions integrally connected at opposite ends of said medial portion, the medial, and first and second lateral portions being made from a first material having a first durometer;annular sealing members integrally co-extruded with the first and second lateral portions, the annular sealing members being made from a second material having a second durometer relatively lower than said first durometer of said first material for forming a fluid-tight seal around a pipe or between piping sections; and a reinforcing section constructed of said first material integrally formed within said first material in said first and second lateral portions, the reinforcing sections covering at least a portion of said annular sealing members wherein said reinforcing sections in said first and second lateral portions have a reduced cross-sectional area relative to the cross-sectional area of said lateral portions surrounding said reinforcing sections. 2. The coupler assembly of claim 1 wherein said reduced cross-sectional area formed by said reinforcing sections in said first and second lateral portions range approximately between .002 and 005 inches in thickness. 3. The coupler assembly of claim 1 wherein said reduced cross-sectional area formed by said reinforcing sections comprise a cross-sectional thickness ranging between one (1) and four (4) percent of the total thickness of the cross-sectional area in said first and second lateral portions surrounding said reinforcing sections. 4. The coupler assembly of claim 1 wherein said medial portion further comprises an undulating medial section comprising first and second stops having a uniform cross-section, the first and second stops functioning as an indicator for positioning piping sections during assembly. 5. The coupler assembly of claim 4 wherein said medial portion farther comprises a riser located between said first and second stops that provides flexibility in the coupler assembly during assembly. 6. The coupler assembly of claim 1, wherein said first durometer ranges between 35 and 50 on a Shore D scale and said second durometer ranges between 40 and 60 on a Shore A scale. 7. A coupler assembly for use with pipe comprising: a unitary annular body forming first and second cylindrical openings for surrounding a pipe or piping sections to facilitate fanning a fluid-tight seal therein, the unitary annular body comprising a medial portion and first and second lateral portions integrally connected at opposite ends of said medial portion, the medial, and first and second lateral portions being made from a first material having a first durometer;annular sealing members facing radially inward of said annular body and integrally formed with the first and second lateral portions, the annular sealing members being made from a second material having a second durometer relatively lower than said first durometer of said first material for forming a fluid-tight seal around a pipe or between piping sections;a plurality of lobes extending from said annular sealing members, the plurality of lobes projecting away from said reinforcing section toward said medial portion for forming a fluid-tight sealing connection in a pipe or between piping sections such that insertion of a pipe into either of said first or second openings biases the contacting sealing members to a pressure enhancing seal; anda reinforcing section integrally formed in said first material in said first and second lateral portions, the reinforcing sections in the first and second lateral portions overlying at least a portion of said annular sealing members, the reinforcing sections having a reduced cross-sectional area relative to the cross-sectional area of first and second lateral portions surrounding said reinforcing section. 8. The coupler assembly of claim 7 wherein said reduced cross-sectional area formed by said reinforcing sections in said first and second lateral portions range approximately between .002 and .005 inches in thickness and the total thickness of the cross-sectional area in said first and second lateral portions surrounding said reinforcing sections ranges approximately between .125 and .187 inches in thickness. 9. The coupler assembly of claim 7 wherein said reduced cross-sectional area formed by said reinforcing sections comprise a cross-sectional thickness ranging between one (1) and four (4) percent of the total thickness of the cross-sectional area in said first and second lateral portions surrounding said reinforcing sections. 10. The coupler assembly of claim 7 wherein said medial portion further comprises an undulating medial section comprising first and second stops having a uniform cross-section, the first and second stops functioning as an indicator for piping sections during assembly. 11. The coupler assembly of claim 10 wherein said media, portion further comprises is riser located between said first and second stops that provides flexibility in the coupler assembly during assembly. 12. The coupler assembly of claim 7 wherein said first durometer ranges between 35 and 50 on a Shore D scale and said second durometer ranges between 40 and 60 on a Shore A scale. 13. The coupler assembly of claim 7 wherein said annular body and seal members comprising first and second durometer materials, respectively, are co-extruded to form the coupler assembly. 14. A coupler assembly for use with pipe comprising: is unitary annular body 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 comprising a medial portion and first and second lateral portions integrally connected at opposite ends of said medial portion to form a continuous structural body, the medial, and first and second lateral portions forming the continuous structural body being made from a first polymeric material having a first durometer;at least one annular sealing member co-extruded with and along a select portion of said continuous structural body, the at least one annular sealing member being made from a second polymeric material having a second durometer relatively lower than said first durometer of said first polymeric material;said medial portion further comprising an undulating medial section having a arcuate riser and first and second arcuate lobes spaced about said arcuate riser, the first and second arcuate lobes curved radially inward and said riser being curved radially outward of said unitary annular body; anda reinforcing section located within and along a select portion of said continuous structural body, the reinforcing section overlying at least a portion of said annular sealing member, the reinforcing sections having a reduced cross-sectional area relative to the cross-sectional area of remaining portions of said continuous structural body.
