ABSTRACT:
A coupling joint for nylon-lined hose comprising a nipple having annular ribs thereon, an o-ring seal disposed in a groove between adjacent ribs and a metal sleeve crimped over the hose. The diameter of the ribs is greater than the ID of the hose requiring a forced insertion therein. The volume of the uncompressed seal is greater than the volume of the groove in which it is disposed. The crimps in the sleeve disposed over the ribs, place the inner liner into contact with the nipple for substantially the entire length thereof in gripping engagement with the ribs and compressing the seal completely into the groove.
