0533567 Regulator Cap is a genuine OEM replacement cap for the pressure regulator on Titan PowrCoat and AirCoat sprayers. This cap seals the regulator body, protects internal components, and often houses the adjustment knob or provides a mounting point for the pressure gauge. A cracked, stripped, or missing regulator cap can cause fluid leaks, loss of pressure control, and contamination of internal parts. Replacing the cap restores proper regulator sealing and protects the regulator assembly.

The Titan 0533567 Regulator Cap is a protective cover that seals the top or side of the pressure regulator assembly on compatible sprayers. It prevents dirt, debris, and coating material from entering the regulator mechanism, while also retaining internal components such as the spring and diaphragm. On some models, the cap also serves as a mounting point for the pressure gauge or adjustment knob.
Over time, regulator caps can become cracked from overtightening, chemical exposure, or impact. A damaged cap may allow fluid leaks, cause loss of spring tension, or permit contaminants to enter the regulator. Replacing the cap with an OEM component ensures a proper seal and protects the regulator's internal parts for reliable pressure control.
