The 0533559 O-ring, Regulator, 423 is a sealing component used in the high-pressure fluid regulator assembly of the AirCoat 423 airless spray system. This O-ring provides a leak‑tight seal between the regulator housing and the adjustment stem, preventing pressurized fluid from escaping the regulator assembly. Over time, O-rings can harden, crack, or become contaminated, leading to fluid leakage around the adjustment knob or pressure instability. If you observe fluid seepage around the regulator, or if the regulator fails to maintain a consistent set pressure, inspect the O-ring for damage. When servicing the regulator, always replace O-rings with genuine Titan components to ensure proper sealing and system integrity. Lubricate the O-ring with compatible grease before installation to prevent binding and ensure a long‑lasting seal.
