The modern design of these nozzle offers the convenience of a more rational alignment system, with a copper seal used between nipple and nozzle tip. The nozzle efficiency is enhaced by means of a carefully designed flow stabilizer, which minimizes turbulence due to sharp direction change at the inlet from the main manifold. Provision is also made for a filter to be mounted at the nozzle inlet, minimizing nozzle clogging and abrasion.
