A hose conducts high-temperature steam combined with cleaning solution in a cleaning operation. The hose comprises an external liner, an intermediate conduit, and an internal liner. The external liner comprises first braiding and is disposed along a longitudinal length of the hose. The intermediate conduit is disposed in the external liner along the longitudinal length of the hose. The intermediate conduit has a plurality of corrugations disposed laterally in the tubular wall of the intermediate conduit. The internal liner comprises second braiding and is disposed in the intermediate conduit along the longitudinal length of the hose. The internal liner provided a full bore for the hose configured to conduct the high temperature steam combined with the cleaning solution in a volatilized mixture.

In an implementation, a hydraulic assembly comprising an end section of a hydraulic hose formed from a volume of material, the end section having a first outer diameter and an open end, is formed by molding a flange in the end section of the hydraulic hose, and threading an annular gasket onto the end section of the hydraulic hose between the flange and the open end of the hydraulic hose, and adjacent to the flange. The flange is formed in the volume of material, and has a second outer diameter greater than the first outer diameter. The molding of the flange may include applying heat to a mold, inserting the open end of the end section of the hydraulic hose into the mold, and thermally deforming a portion of the end section of the hydraulic hose to form the flange.

A fluid connector assembly comprising a reversible connector body having female and male end portions. The male end portion having an outer diameter smaller than the outer diameter of the female end portion. The female end portion including an internal bore extending through the female end portion from an annular opening to an inner seat. The male end portion including an internal bore extending from an abutment face at a head end of the male end portion to an opening at the female end portion inner seat. A first tube having a concave flared end installed on the inner seat of the reversible connector body engages a spherical/convex flared end of a second tube installed on the abutting face of another reversible connector body when the male end portion of the another reversible connector body is installed in the female end portion of the reversible connector body.

A fitting body includes a tubular end whose outer periphery has an external thread and whose inner periphery has an annular groove or protrusion. A sleeve connects a tube to the tubular end of the fitting body. A union nut includes a first axial end that receives the tube therein and a second axial end to be screwed onto the external thread of the fitting body. The fitting body includes first and second regulating portions extending in directions that intersect an axial direction of the fitting body to contact the union nut being screwed onto the external thread and then sharply raise torque to be transmitted through the union nut to a hand of a worker. When being screwed onto the external thread, the union nut contacts the first regulating portion and subsequently the second regulating portion.
