Abstract
A hose coupler generally includes a hose adapter including opposing ends, an interior surface forming a fluid passage between the opposed ends, and an exterior surface including a series of barbs for engaging an interior surface of a hose that is configured to be fluidly connected to the hose adapter. A ferrule is connected to the hose adapter and is positioned to at least partially surround the exterior surface of the hose adapter. The ferrule has an interior surface facing the exterior surface of the hose adapter. The interior surface defines at least one cutting rib having a sharp corner or edge for piercing an outer layer of the hose and a plurality of compression ribs each defining a rounded surface for compressing the hose against the barbs.
Claims19
A hose coupler comprising:
- a hose adapter including opposing ends, an interior surface forming a fluid passage between the opposed ends, and an exterior surface including a series of barbs for engaging an interior surface of a hose;
- and
- a ferrule connected to the hose adapter at an attachment point and positioned to at least partially surround the exterior surface of the hose adapter, the ferrule having an interior surface facing the exterior surface of the hose adapter, the interior surface of the ferrule defining at least one cutting rib having a sharp corner or edge for piercing an outer layer of the hose, and the interior surface of the ferrule defining a plurality of compression ribs each having a rounded surface disposed on the interior surface of the ferrule for compressing the hose against the series of barbs.
The hose coupler of claim 6, wherein one or more of the compression ribs are positioned between the cutting ribs.
The hose coupler of claim 6, wherein the cutting ribs extend to different depths as measured from the interior surface of the ferrule.
A ferrule for mounting a hose to a hose adapter, said ferrule comprising a substantially cylindrical hollow structure extending between a proximal end and a distal end, an attachment surface at the proximal end of the ferrule that is configured to be connected to the hose adapter, wherein an interior surface of the ferrule, which is positioned to face the hose adapter, includes at least one cutting rib having a sharp corner or edge for piercing an outer layer of the hose and a plurality of compression ribs each having a rounded surface for compressing the hose against the hose adapter.
