Abstract

An assembly is provided for a fluid system. This fluid system assembly includes a fluid conduit and a plug. The fluid conduit has an internal bore. The internal bore is configured as or otherwise includes a smooth-walled internal bore. The plug includes a protrusion and a head. The protrusion is connected to the head. The protrusion projects axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug. The head is seated against the fluid conduit. The head seals an opening in the fluid conduit to the internal bore.

Claims (33)

1. An assembly for a fluid system, comprising:

a fluid conduit with an internal bore, the internal bore comprising a smooth-walled internal bore; and

a plug including a protrusion and a head, the protrusion connected to the head and projecting axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug, and the head seated against the fluid conduit and sealing an opening in the fluid conduit to the internal bore;

wherein at least a portion of the protrusion is twisted about the axial centerline.

2. The assembly of claim 1 , wherein at least a portion of the protrusion has a polygonal cross-sectional geometry.

3. The assembly of claim 1 , wherein the head comprises a wrenching feature.

4. The assembly of claim 3 , further comprising:

a nut securing the plug to the fluid conduit;

the head projecting axially through an aperture in the nut towards the wrenching feature.

5. The assembly of claim 1 , wherein the head is seated against the fluid conduit at a cone seal interface.

6. The assembly of claim 1 , further comprising a nut securing the plug to the fluid conduit.

7. The assembly of claim 6 , wherein

the nut includes a sleeve and an inner rim;

the sleeve is mated with the fluid conduit at a threaded interface; and

the head is sandwiched axially between the inner rim and an end of the fluid conduit.

8. An assembly for a fluid system, comprising:

a fluid conduit with an internal bore, the internal bore comprising a smooth-walled internal bore; and

a plug including a protrusion and a head, the protrusion connected to the head and projecting axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug, and the head seated against the fluid conduit and sealing an opening in the fluid conduit to the internal bore;

wherein the plug further includes a flexible wire bristle pack arranged within the internal bore and attached to the protrusion.

9. The assembly of claim 8 , wherein the head comprises a wrenching feature.

10. The assembly of claim 9 , further comprising:

a nut securing the plug to the fluid conduit;

the head projecting axially through an aperture in the nut towards the wrenching feature.

11. The assembly of claim 8 , wherein the head is seated against the fluid conduit at a cone seal interface.

12. The assembly of claim 8 , further comprising a nut securing the plug to the fluid conduit.

13. The assembly of claim 12 , wherein

the nut includes a sleeve and an inner rim;

the sleeve is mated with the fluid conduit at a threaded interface; and

the head is sandwiched axially between the inner rim and an end of the fluid conduit.

14. An assembly for a fluid system, comprising:

a fluid conduit with an internal bore, the internal bore comprising a smooth-walled internal bore; and

a plug including a protrusion and a head, the protrusion connected to the head and projecting axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug, and the head seated against the fluid conduit and sealing an opening in the fluid conduit to the internal bore;

wherein at least a portion of the axial centerline is non-straight and the protrusion comprises flexible material.
