Abstract
A push-to-connect fitting assembly, device and method allows for continual contact of inserted tubing with a main body member so as to maintain conductivity for electrical applications and a tight, rotation-restricting seal. In various embodiments, an axially internal portion of the device has an interior surface that tapers from a narrower radius to a wider radius as it extends outwardly from a tube stop element to an outer rim.

A fitting, comprising:
- a main body component comprising an interior surface and an exterior surface, wherein the interior surface defines a cavity extending along an axis through the main body component, wherein the main body component further comprises a first segment having an axially inner portion, an axially intermediate portion and an axially outer portion, with the axially inner portion, axially intermediate portion and axially outer portion of the first segment being integrally formed and each comprising a respective interior radius from the axis to the interior surface, wherein the interior surface extends at a first acute angle to the axis from a radially innermost point of the interior surface to an axially outer rim of the axially inner portion of the first segment of the main body component, wherein the main body component further comprises a second segment having a second segment axially inner portion, wherein the interior surface extends at a second acute angle to the axis from the radially innermost point of the interior surface to an axially outer rim of the second segment axially inner portion, wherein the axially outer portion comprises an axially outer rim extending radially inwardly from the interior surface of the main body component, wherein the axially outer rim comprises a radially inner edge having an axially inner edge and an axially outer edge, wherein the axially inner edge of the radially inner edge of the axially outer rim has an internal radius that is substantially the same as the interior radius of the axially intermediate portion of the first segment of the main body component, wherein the internal radius of the axially inner edge of the radially inner edge of the axially outer rim is less than the internal radius of the axially outer edge of the radially inner edge of the axially outer rim, and wherein the first element is configured to receive a piping element abutting the radially innermost point of the interior surface, wherein the received piping element has an outer diameter that is larger than an internal diameter of the radially innermost point of the interior surface.
A method of forming a fitting conduit, comprising:
- forming a main body component with an interior surface and an exterior surface, wherein the interior surface defines a cavity extending along an axis through the main body component;
- wherein the main body component comprises a first segment having an axially inner portion, an axially intermediate portion and an axially outer portion, with the axially inner portion, axially intermediate portion and axially outer portion of the first segment being integrally formed and each comprising a respective interior radius from the axis to the interior surface, wherein the interior surface is formed so as to extend at a first acute angle to the axis from a radially innermost point of the interior surface to an axially outer rim of the axially inner portion of the first segment of the main body component, wherein the main body component further comprises a second segment having a second segment axially inner portion, and wherein the interior surface extends at a second acute angle to the axis from the radially innermost point of the interior surface to an axially outer rim of the second segment axially inner portion, wherein the axially outer portion comprises an axially outer rim extending radially inwardly from the interior surface of the main body component, wherein the axially outer rim comprises a radially inner edge having an axially inner edge and an axially outer edge, wherein the axially inner edge of the radially inner edge of the axially outer rim has an internal radius that is substantially the same as the interior radius of the axially intermediate portion of the first segment of the main body component, and further wherein the internal radius of the axially inner edge of the radially inner edge of the axially outer rim is less than the internal radius of the axially outer edge of the radially inner edge of the axially outer rim;
- and
- inserting a piping element within the first segment of the main body component so as to abut the radially innermost point of the interior surface, wherein the interior surface of the main body component has an internal diameter, and wherein the piping element has an outer diameter that is larger than the internal diameter of the radially innermost point of the interior surface.
