Pipe coupling system and method

A coupler assembly for forming a fluid-tight seal during use with a pipe or piping sections, the coupler assembly comprising:

• a unitary annular body extruded to form first and second cylindrical openings for surrounding a pipe or piping sections during use;
• the unitary annular body comprises an undulating medial portion and first and second longitudinal portions integrally extruded to opposite ends of the medial portion;
• and
• extending from the first and second longitudinal portions away from the medial portion are respective first and second locking arrangements for securing the coupler assembly to a pipe or piping sections;
• wherein said first and second locking arrangements further comprise a support end and a spaced engagement end located at opposite ends of a locking body, the locking body being transversely oriented to said longitudinal portions such that said support end extending from said engagement end trusses the coupler, strengthening the coupler from deflection or separation during use.

A coupler assembly for forming a fluid-tight seal during use with a pipe or piping sections, the coupler assembly comprising:

• a unitary annular body extruded to form first and second cylindrical openings for surrounding a pipe or piping sections during use;
• the unitary annular body comprises a medial portion and first and second longitudinal portions integrally extruded in opposite ends of the medial portion;
• and
• extending from the first and second longitudinal portions away from the medial portion are respective first and second flex members having relatively flexible material structure relative to the remaining unitary annular body, allowing for rotational movement about the flex member, the flex member further for securing the coupler assembly to a pipe or piping sections, the flex members transversely oriented radially inward through a first region then expanding radially outward through a second region wherein said flex members further comprise a first material having a first durometer value and said medial portion and longitudinal portions having a second material having a second durometer value wherein said second durometer value is higher than said first durometer value.
