Abstract
The hose sub-assembly is provided with a nozzle assembly at each end which includes a fitting with a flat transverse end surface. In addition, a nut which carries an O-ring in a recess at the end surface is threaded into a sleeve in which the nozzle assembly is mounted. The O-rings provide a flat surface-to-surface sealing arrangement to reduce the risk of damage to the O-ring while enhancing the sealing characteristics. Each nut and O-ring is biased against the nozzle assembly by a stretched outer metal casing.
