Titan part 0533544 is an adjustment knob used on the AirCoat 423 airless/air‑assisted sprayer. This knob attaches to the pressure regulator or control valve stem, allowing the operator to easily adjust fluid pressure by hand. A cracked, stripped, or missing knob makes pressure adjustment difficult or impossible, leading to poor spray performance. Replacing with the OEM knob restores precise, comfortable pressure control.

The Titan 0533544 Adjustment Knob is a genuine OEM replacement knob for the pressure regulator on the AirCoat 423 airless/air‑assisted sprayer. It features an ergonomic, non‑slip grip and a molded‑in stem socket that fits securely onto the regulator adjustment shaft.
Over time, adjustment knobs can become cracked from overtightening, stripped internally, or lost during maintenance. A damaged or missing knob prevents fine pressure adjustment, forcing the operator to use pliers or other tools that can damage the regulator stem. Replacing with OEM Titan 0533544 restores convenient, tool‑free pressure control.
