A high pressure fluid transmission nozzle. The nozzle comprises a circular fluid transmitting tubing threaded in close proximity to a tubing discharge end for receiving a complementary threaded, circular collar. Overriding the tubing and collar is a circular gland nut, where the circular gland nut may include an externally threaded shank portion. The circular collar and circular gland nut are each characterized by a pair of radially aligned through holes, where a given pair are diametrically aligned to pass through the axis of the circular fluid transmitting tubing. The holes are adapted to receive a hand tool, such as a spanner tool, to disengage the collar and gland from the tubing. Further, to facilitate the disengagement, the contact engaging surfaces are impregnated with a permanent film lubricant, such as a thermosetting resin.
