Abstract
Example aspects of a tight-seal piping component, a tight-seal piping assembly, and a method for preventing leaking in a piping assembly are disclosed. The tight-seal piping component can comprise a fitting body defining a fitting inner surface, a fitting outer surface opposite the fitting inner surface, a first fitting end, and a second fitting end opposite the first fitting end, the fitting inner surface defining: an interior channel defining a fitting axis; a seal stop surface within the interior channel; and internal threading between first fitting end and the seal stop surface, the internal threading defining straight threading extending in a direction about perpendicular to the fitting axis; and a seal received within interior channel and abutting seal stop surface.
Claims26
A tight-seal piping assembly comprising:
- a connecting piping component defining a component axis and comprising:
- an outer piping surface;
- an inner piping surface opposite the outer piping surface;
- exterior threading defined in the outer piping surface;
- and
- a piping end comprising:
- a portion of the outer piping surface oriented substantially parallel to the component axis of the connecting piping component and extending from the piping end to the exterior threading on the connecting piping component;
- and
- a pipe engagement surface extending at an acute angle to the component axis from the inner piping surface to the outer piping surface;
- and
- a tight-seal piping component comprising:
- a fitting body defining a fitting inner surface, a fitting outer surface opposite the fitting inner surface, a first fitting end, and a second fitting end opposite the first fitting end, the fitting inner surface defining:
- an interior channel defining a fitting axis and an inner diameter;
- a groove defining an outer diameter;
- a seal stop surface abutting the groove within the interior channel;
- and
- internal threading spaced axially inward from the first fitting end and disposed between the first fitting end and the groove, the internal threading defining the inner diameter defined by straight threading extending in a direction about perpendicular to the fitting axis;
- and
- a seal received within the outer diameter of the groove in the interior channel and abutting the seal stop surface, wherein:
- the outer diameter of the groove is greater than the inner diameter of the internal threading;
- and
- in an engaged position defined by the connecting piping component and the tight-seal piping component, the seal is compressed in the groove between the outer diameter of the groove and the portion of the outer piping surface of the piping end.
A tight-seal piping assembly comprising:
- a fitting body defining a fitting inner surface, the fitting inner surface defining an interior channel with an inner diameter and a groove comprising an outer diameter that is greater than the inner diameter, a seal stop surface within the interior channel, and straight threading spaced axially from a first fitting end of the fitting body within the interior channel and oriented between the seal stop surface and the first fitting end of the fitting body;
- a connecting piping component comprising an outer piping surface defining mating straight threading proximate to a first piping end of the connecting piping component, and a pipe engagement surface oriented at an angle to the outer piping surface, wherein the fitting body and the connecting piping component define an engaged position in which the first piping end of the connecting piping component is received within the interior channel and the straight threading is rotationally engaged with the mating straight threading;
- and
- a seal defining an outer seal surface received within the outer diameter of the groove in the interior channel and wherein, in the engaged position:
- the outer piping surface of the connecting piping component extends into the groove;
- the seal is compressed in the groove between the seal stop surface and the first piping end of the connecting piping component;
- and
- the seal expands into the groove between the outer diameter of the groove and the outer piping surface of the connecting piping component.
