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.
Claims18
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, wherein the main body component further comprises a tube stop extending radially inwardly from the interior surface into the cavity, wherein the tube stop comprises an axially extending wall and first and second radially extending walls, and wherein the interior surface extends at an acute angle to the axis from the first radially extending wall of the tube stop to an axially outer rim of the axially inner portion of the first segment of the main body component, whereby a piping element inserted into the cavity can slidingly contact the interior surface from the axially outer rim of the axially inner portion of the first segment to the tube stop.
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 and a second segment each 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 being integrally formed and each comprising a respective interior radius from the axis to the interior surface, and wherein the interior radius of the axially inner portion increases from a radially innermost point to an axially outer rim of the axially inner portion of the main body component, and the interior surface of the axially inner portion extends at an acute angle to the axis from the radially innermost point to the axially outer rim, and the interior surface of the first segment and the interior surface of the second segment connect each other at the radially innermost point such that two piping elements can be respectively secured within the first segment and the second segment of the main body component so as to abut the radially innermost point.
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, wherein the interior surface extends at an 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, whereby a piping element inserted into the cavity can slidingly contact the interior surface from the axially outer rim of the axially inner portion of the first segment to the radially innermost point of the interior surface.
