Abstract
Described herein is a novel method and apparatus for preventing spark propagation from a hydraulic joint to a surrounding medium, such as a fuel source. The hydraulic joint includes a fitting and a tube. A tip seal may be placed about the edge of the hydraulic fitting or a sleeve may be placed about the joint, each resulting in an independent mechanical barrier between the joint and surrounding medium, thereby preventing spark propagation to the surrounding medium.
