Abstract
A flexible hose adapter configured for engagement with a coupling, the flexible hose adapter including an end piece, the end piece defining an inner end and an outer end, the end piece defining an axis extending from the inner end to the outer end, the end piece defining a raised lip, a sealing surface, and a groove, the raised lip axially positioned at the inner end, the sealing surface positioned between the raised lip and the groove; and a flexible hose attached to the outer end of the end piece.
Claims16
A pre-assembled coupling assembly comprising:
- a coupling defining a first ridge and a second ridge positioned opposite from the first ridge, the coupling defining a coupling bore extending from the first ridge to the second ridge, the coupling comprising a gasket positioned within the coupling bore between the first ridge and the second ridge, the gasket defining a sealing ridge;
- and
- a hose adapter comprising:
- an end piece defining an inner end and an outer end, the end piece defining an axis extending from the inner end to the outer end, the end piece defining a raised lip, a sealing surface, a groove, and a stop lip comprising a circumferential gap, the stop lip positioned at the inner end, the sealing surface axially positioned between the raised lip and the groove, the inner end axially positioned between the first ridge and the second ridge, the coupling retained on the inner end when the coupling is in a relaxed position wherein:
- the sealing ridge is axially positioned between the raised lip and the groove;
- and
- a radially innermost portion of the sealing ridge is positioned radially inward from a radially outermost portion of the raised lip.
A pre-assembled coupling assembly comprising:
- a hose adapter comprising an end piece defining a raised lip, a sealing surface, a groove, and a stop lip comprising a circumferential gap, the stop lip positioned at a first end opposite the groove, the sealing surface axially positioned between the raised lip and the groove;
- and
- a coupling retained on the first end and coupled to the coupling when the coupling is in a relaxed position,
- wherein the coupling comprises a gasket defining a sealing ridge axially positioned between the raised lip and the groove, and the sealing ridge contacts the sealing surface in the relaxed position.
