Hose Expansion Rings

    These must be installed with an internal expansion machine and can be reused (except expansion rings and possibly the tail gasket). When installing these fittings it is critical that the internal tail gasket is compressed by the expansion ring - or a hose leak or failure will result within several feet from the end of the hose.  

    The 'bowl size' of a fire hose coupling represents the inside diameter of the expansion side (the thicker the hose wall is, the larger the bowl size).
