A hose assembly (100, 200) comprising: an inner core tube (110, 210); a first coupling member (132, 232) having an inboard nose portion (133, 233) extending into a flared first end (111, 211) of the inner core tube; a metal outer tube (120, 220) surrounding the inner core tube and terminating at a first end (121, 221) axially inward of the first end of the inner core tube, with an outer cavity disposed between the inner core tube and the metal outer tube; and a first collar (131, 231) having: an outboard clamping portion (137, 237) surrounding the nose portion for clamping retention of the first end of the inner core tube therebetween; and an inboard venting portion (147, 247) welded to the first end of the metal outer tube, the inboard venting portion including a venting port (148, 248) in fluid communication with the outer cavity; wherein: an outboard end (137a, 237a) of the outboard clamping portion has a first inner diameter sized to accommodate the flared first end of the inner core tube; an inboard end (137b, 237b) of the outboard clamping portion includes a radially inward protrusion (138, 238) having a second inner diameter smaller than the first inner diameter and sized to impede withdrawal of the flared first end of the inner core tube from the first collar; and the inboard venting portion has a third inner diameter larger than the second inner diameter and sized to permit fluid flow between the outer cavity and the venting port. an inner core tube (110, 210); a first coupling member (132, 232) having an inboard nose portion (133, 233) extending into a flared first end (111, 211) of the inner core tube; a metal outer tube (120, 220) surrounding the inner core tube and terminating at a first end (121, 221) axially inward of the first end of the inner core tube, with an outer cavity disposed between the inner core tube and the metal outer tube; and a first collar (131, 231) having: an outboard clamping portion (137, 237) surrounding the nose portion for clamping retention of the first end of the inner core tube therebetween; and an inboard venting portion (147, 247) welded to the first end of the metal outer tube, the inboard venting portion including a venting port (148, 248) in fluid communication with the outer cavity; an outboard clamping portion (137, 237) surrounding the nose portion for clamping retention of the first end of the inner core tube therebetween; and an inboard venting portion (147, 247) welded to the first end of the metal outer tube, the inboard venting portion including a venting port (148, 248) in fluid communication with the outer cavity; an outboard end (137a, 237a) of the outboard clamping portion has a first inner diameter sized to accommodate the flared first end of the inner core tube; an inboard end (137b, 237b) of the outboard clamping portion includes a radially inward protrusion (138, 238) having a second inner diameter smaller than the first inner diameter and sized to impede withdrawal of the flared first end of the inner core tube from the first collar; and the inboard venting portion has a third inner diameter larger than the second inner diameter and sized to permit fluid flow between the outer cavity and the venting port.
