ABSTRACT:
A pipe coupling is disclosed for coupling together complimentary flexible hoses. The pipe coupling includes a first tubular member having a first and a second end, the first end of the first member defining a first bore and a first counterbore. A second tubular member has a first and a second end and the first end of the second member defines a second bore and a second counterbore. The second counterbore is of the same diameter as the first counterbore and is aligned with the first counterbore when the first and the second members are coupled together. A tubular insert includes a first and a second end and the insert extends between the first and the second bores such that the external surface of the insert engages the first and the second bores with the first end of the insert being disposed adjacent the first bore and the second end of the insert being disposed adjacent the second bore. An annular seal is disposed in an annular space defined by the first and the second counterbores and the insert. The annular seal seals the first and the second members together when the members are coupled together.
