The 773-153 needle and nozzle set is a precision-matched pair of components that control fluid flow and atomization in compatible HVLP spray guns. It is specifically designed for use with HVLP Airspray C100 Gun; HVLP Airspray ProFinish Gun; and HVLP Airspray Profinish TS40 TS 50 models. The nozzle contains a precisely sized orifice that meters the fluid, while the needle has a tapered tip that fits into the nozzle to start and stop the flow. When the trigger is pulled, the needle retracts, allowing fluid to pass through the nozzle and be atomized by the air stream. The precise fit between the needle and nozzle is critical for achieving a consistent spray pattern and a high-quality finish. These components are manufactured from wear-resistant materials such as hardened stainless steel to withstand the abrasive nature of paints. Over time, needles and nozzles can wear, causing the spray pattern to deteriorate, leading to issues such as spitting, uneven distribution, or overspray. Symptoms of a worn set include a change in spray pattern, difficulty adjusting fluid flow, or the gun dripping when shut off. Replacing a worn needle/nozzle set with this genuine matched pair restores the gun's performance, ensuring a smooth, even finish. When replacing, it is important to clean the gun thoroughly and ensure the new components are correctly installed.
