Patent ID: 7604261

Claim:
A pipe assembly comprising: a coupler body having a bore extending therethrough, said bore defining opposed end portions terminating in an end opening, each of said end portions having a first inner linear length and a second outer linear length, a metal conduit receivable in each of said opposed end portions, each of said first inner linear length having a shape and size to snugly receive an end portion of an associated metal conduit, and each of said second outer linear length having an internal surface that diverges outwardly toward an associated end opening, a tubular sealing gland having a bore sized to be fitted onto the end portion of each of said metal conduits, each of said tubular sealing glands having a diverging outer surface complementing the diverging interior surface of said second linear length, a metallic split compression ring loosely fitted onto the end portion of each of said metal conduits, and a fastening nut fitted onto the end portion of each of said metal conduits for securing each of said metal conduits to each of said opposed end portions whereby said sealing gland is urged into sealing relationship with said internal surface of an associated second linear length, and compressing said metallic compression ring onto said metal conduit, said bore including an internal stop shoulder defining a stop to limit the distance each of said metal conduits is inserted into its corresponding end portion, and an intermediate shoulder within each of said end portions longitudinally spaced from said stop shoulder to define said first linear length from said second linear length in said end portions.
