Abstract: An improved fluid jet apparatus which may be used to ensure a consistent and precise jet of fluid in a vibrating or otherwise unstable environment and a method of manufacturing such an apparatus. The apparatus generally comprises stainless steel base and nozzle members which are securely attached to each other by a silver braze down the length of a drilled hole and a needle valve which is set with a recessed set screw, such set screw being protected by hot wax in the recessed area. The apparatus may further be mounted upon a stainless steel standoff with another recessed set screw which is adapted to sustain sufficient pressure for anchoring the nozzle apparatus in an unstable or vibrating environment.
