Abstract
A pipe end fitting or coupling including an elongated tubular body having a bore at its first end and a counterbore at its second end with the counterbore being formed as a plurality of frusto-conical grooves and with each of the grooves converging toward its second end. A support sleeve is mounted within the bore and extends throughout the counterbore to form an annular chamber. A cylindrical pipe may be fitted into the annular chamber to form respective chambers with each of the grooves. The respective chambers are filled with a hardenable epoxy resin to complete the end fitting connection.
