Abstract
A press fitting device, components and method provide one or more indicators to provide a visual indication that the fitting has been properly pressed around a tube and that the correct amount of pressure has been provided to create a permanent seal. In embodiments, a sealing ring is retained within an indentation of a main body component of the fitting and the sealing ring is expandable upon compression to be visible through an opening in the main body component.
Claims18
A fitting, comprising:
- a main body component having interior and exterior surfaces, wherein the interior surface defines a cavity extending through the main body component along an axis, wherein the interior surface comprises an axially inner segment and an axially outer segment, wherein the axially outer segment is formed with an indentation comprising a radial distance from the axis that is greater than a radial distance from the axis to the axially inner segment, wherein the axially outer segment is further formed with an opening extending radially therethrough, wherein the opening is formed at least partially along the indentation;
- and
- a sealing ring securely maintained within the indentation, wherein the sealing ring comprises an axially outer edge that lies axially aligned with or axially inwardly of the opening when the sealing ring is at rest and lies axially outwardly of the first axial position of the opening when the sealing ring is compressed.
A fitting, comprising:
- a main body component having interior and exterior surfaces, wherein the interior surface defines a cavity extending through the main body component along an axis, wherein the interior surface comprises an axially inner segment and an axially outer segment, wherein the axially outer segment is formed with an indentation comprising an axially inner part and an axially outer part, and wherein the axially outer part is formed with an opening extending radially therethrough, wherein the axially, impart of the indentation extends from the axially inner segment on a first curve to an apex of the indentation and wherein the axially outer part of the indentation extends on a second curve from the apex of the indentation to an axially outer floor portion of the axially outer segment of the main body component, wherein the opening extends through the second curve and wherein the second curve is formed with concave portion and a convex portion;
- and
- a sealing ring securely maintained within the indentation.
A fitting, comprising:
- a main body component having interior and exterior surfaces, wherein the interior surface defines a cavity extending through the main body component along an axis, wherein the interior surface comprises an axially inner segment and an axially outer segment, wherein the axially outer segment is formed with an indentation comprising a radial distance from the axis that is greater than a radial distance from the axis to the axially inner segment, wherein the axially outer segment is further formed with an opening extending radially therethrough, wherein the opening is formed at least partially along the indentation, wherein the indentation comprises an axially inner part and an axially outer part, wherein the axially inner part of the indentation is formed with a convex portion and extends from the axially inner segment on a first curve to an apex of the indentation, and wherein the axially outer part of the indentation is formed with a concave portion and a convex portion;
- and
- B a sealing ring securely maintained within the indentation.
