Title: Hose coupling

Abstract: A hose coupling secures a flexible hose member having a radially outwardly facing exterior hose surface and a radially inwardly facing interior hose surface. The hose coupling includes a housing having a radially outwardly facing exterior surface and a radially inwardly facing interior surface defining a longitudinal passageway, a first axial end, and a second axial end. The interior surface includes a first ramped portion and a first seating portion. A tube support member has a tube portion disposed in the interior longitudinal passageway of the housing and a base portion fixedly coupled to the housing at the second axial end of the housing. The base portion has a seal seat region, and the tube portion has a radially outwardly facing exterior surface that includes a first grip ring for supporting the interior hose surface. The first grip ring is circumferentially disposed about the exterior hose surface. A seal is disposed between the first seating portion of the housing and the seal seat region of the tube support member. A grip/release mechanism is disposed in the longitudinal passageway of the housing concentrically exteriorly of the tube portion of the tube support member. The grip/release member is axially moveable relative to the housing and has a third axial end, a radially inwardly facing, axially extending interior surface defining an interior longitudinal passageway, and a radially outwardly facing, axially extending exterior surface. The grip/release member interior surface includes a circumferentially disposed sealing grip ring and a circumferentially disposed barbed grip ring disposed toward the third axial end relative to the grip ring. The sealing grip ring exerts a compressive force on the exterior hose surface and the barbed grip ring grips the exterior hose surface by exerting an expansive force. The grip/release mechanism exterior surface includes a second ramped portion.
