Abstract
An assembly configured to be press joined with a pipe by a pressing tool includes a piping component, which includes a body, a first end having a rim and an inner surface having a plurality of grooves, and a sealing recess wall positioned between the first end and the body and defining a sealing recess. The assembly also includes a sealing element received within the sealing recess of the piping component and having a sealing element thickness. The sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element.
Claims20
An assembly configured to be press joined with a pipe by a pressing tool, comprising:
- a piping component, comprising:
- a body;
- a first end having a rim and an inner surface having a plurality of grooves;
- and
- a sealing recess wall positioned between the first end and the body and defining
- a sealing recess;
- and
- a sealing element received within the sealing recess of the piping component and having a sealing element thickness, wherein the sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element.

An assembly configured to be press joined with a pipe by a pressing tool, comprising:
- a piping component, comprising:
- a body
- a first end having a rim;
- and
- a sealing recess wall positioned between the first end and the body and defining a sealing recess;
- and
- a sealing element received within the sealing recess of the piping component, wherein a sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element,
- wherein the pressing tool comprises:
- first and second pressing jaws each having a proximal end and a distal end and being operable between an open condition, wherein the distal ends are separated from each other, and a closed condition, wherein the distal ends are in contact with each other,
- wherein the first pressing jaw includes a first pressing geometry that forms a first end-crimping portion configured to crimp a first end of the piping component, a second pressing geometry that forms a sealing recess-pressing portion configured to receive and press a sealing recess wall of the piping component, and a third pressing geometry that forms a body-crimping portion configured to crimp a body of the piping component,
- wherein the first pressing geometry is spaced apart axially from the second pressing geometry and extends axially from an inner periphery that is a first distance from the second pressing geometry to an outer periphery that is a second distance from the second pressing geometry, wherein the second distance is greater than the first distance, and
- further wherein the third pressing geometry is spaced apart axially from the first pressing geometry, such that the second pressing geometry is positioned axially between the first and third pressing geometries, and the third pressing geometry extends axially from an inner periphery that is a third distance from the second pressing geometry to an outer periphery that is a fourth distance from the second pressing geometry, wherein the fourth distance is greater than the third distance, and
- wherein if the sealing recess wall is received within the sealing recess-pressing portion and a crimp width of the pressing tool is about equal to and not greater than a Maximum Crimp Width Value of the pressing tool, the outer periphery of the first pressing geometry is positioned axially between the rim of the first end and the sealing recess wall.
10 more elements
A method of press joining a piping component with a pipe via a pressing tool, comprising the steps of:
- inserting the pipe into the piping component, wherein the piping component has a sealing element received within a sealing recess defined by a sealing recess wall of the piping component, wherein the sealing element has a sealing element thickness and the sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element;
- and
- pressing the pipe and piping component with the pressing tool, such that a sealing recess-pressing portion of the pressing tool presses the sealing recess wall of the piping component and a first end-crimping portion of the pressing tool crimps a first end of the piping component between the sealing recess wall and a rim of the first end positioned distally from the sealing recess wall, and such that the pipe is operable to withstand 2 million vibration cycles at an amplitude of 0.125 inches and a frequency of 16.67 Hertz under a UL 109 vibration test without breakage along the rim of the first end.
