Abstract

A fitting (30) for fluid communication with a fluid conduit includes a first fluid conduit connection portion (42), a second fluid conduit connection portion (42′), a header (60) disposed axially between the first fluid conduit connection portion and the second fluid conduit connection portion, and a socket (70). A fluid fitting may include a nipple (40), a radial projection (48) connected to the nipple, and an axial protrusion (120) extending from the radial projection. The axial protrusion may be configured to protrude into an axial end of a fluid conduit (80). A fluid fitting may include a fluid conduit connection portion (42) and a dynamic tip (130) connected to an end of the fluid conduit connection portion. The dynamic tip may be configured to expand in response to an increase in fluid pressure.

Claims23

Dependent claims

A fluid fitting, comprising;

a first fluid conduit connection portion forming an axial protrusion that extends to an outermost longitudinal end, wherein the axial protrusion includes a first tapered surface extending from the outermost longitudinal end, a longitudinally extending surface extending from the first tapered surface, and a second tapered surface extending from the longitudinally extending surface;
a second fluid conduit connection portion;
a header disposed axially between the first fluid conduit connection portion and the second fluid conduit connection portion;
a sealing sleeve forming an axially-extending recess including inner and outer diameters with respective inner and outer retaining features to opposingly engage corresponding inner and outer surfaces of a fluid conduit;
a nipple with a radial projection connected to the nipple;
and a socket;
wherein the axial protrusion inwardly tapers to a pointed leading end that is configured to provide a seal by protruding into an axial end of a fluid conduit;
and the axial protrusion includes a convexed arch surface extending from the second tapered surface and a second longitudinal surface extending from the convexed arch surface.
