Abstract
A connection and a method of providing a connection includes a fluid tight communication between a valve and a tube. The valve includes a first surface, a second surface, a cavity, and an aperture extending through the valve between the first and second surfaces. The tube includes a first portion, a second portion and a third portion between the first and second portions. The first portion penetrates the first surface and extends through the aperture into the cavity. The third portion is deformed so as to engage the second surface.
Claims6
A connection for communicating fluid, the connection comprising:
- a body having an exterior surface, an interior surface defining a generally cylindrical volume having a central axis, and a passage extending along an axis generally perpendicular to the central axis and connecting the interior and exterior surfaces;
- and
- a tube extending along the axis and being at least partially located within the passage, the tube including:
- a first portion,
- a second portion spaced alone the axis from the first portion, and
- a third portion axially spaced between the first and second portions, the third portion being deformed to engage the interior surface and prevent rotation of the tube about the axis;
- wherein the interior surface includes a saddle formation surrounding the passage, the saddle formation being defined by the intersection of the passage with the interior surface, and the third portion includes deformation engaging the saddle formation so as to prevent the tube from rotating about the axis.
