Titan 773-003 Retaining Ring

Retaining ring 773-003 for HVLP spray guns

The 773-003 retaining ring is a small but critical fastener used to secure components within the assembly of compatible HVLP spray guns. It is designed to fit into a precision-machined groove, holding parts such as air caps, fluid nozzles, or needle guides in place. This ring is compatible with HVLP Airspray Profinish TS40 TS 50; HVLP Airspray ProFinish Gun; and HVLP Airspray C100 Gun models. Its function is to prevent these components from shifting or dislodging during operation, which could affect spray pattern quality or cause fluid leaks. The ring is typically made of spring steel, allowing it to snap into the groove and maintain tension. Over time, retaining rings can become weak, deformed, or lost during disassembly for cleaning or repair. A missing or damaged ring can lead to loose parts, misalignment, and poor gun performance. Symptoms of a faulty retaining ring include components that feel loose, unusual vibration, or changes in spray pattern. Replacing a worn or missing ring with this genuine part restores the secure fit of internal components. It is a simple and inexpensive fix that ensures the spray gun operates reliably. When installing, care should be taken to fully seat the ring in the groove and to avoid overstretching.
