0533930 Kit, Body Connector O-Ring is a genuine OEM replacement o‑ring kit for the body connector on Titan AirCoat 423 sprayers. This kit contains the precision o‑rings needed to seal the connection between the regulator body, manifold, or fluid housing, preventing fluid leaks and air ingestion. Worn, hardened, or cracked o‑rings in body connectors can cause fluid seepage, loss of prime, and pressure instability. Replacing the o‑rings with this kit restores leak‑free sealing and reliable sprayer operation.

The Titan 0533930 Kit, Body Connector O-Ring is a set of precision elastomeric seals used in the fluid connections between major components of the AirCoat 423 sprayer. These o‑rings seal joints such as the regulator body to the manifold, fluid housing to the pump, or other critical body connector points. A proper seal is essential to prevent coating material leaks and to stop air from being drawn into the fluid system.
O‑rings in body connectors are exposed to coatings, solvents, and mechanical stress. Over time, they can harden, flatten, crack, or swell, leading to fluid leaks, loss of prime, pressure fluctuations, or foaming material. Replacing the o‑rings with this OEM kit restores leak‑free sealing and ensures consistent spray performance.
| Fluid sealing | Prevents leaks between regulator body, manifold, and fluid housing |
|---|---|
| Air exclusion | Stops air from entering the fluid system through connector joints |
| Pressure integrity | Maintains hydraulic pressure by blocking bypass paths |
| Fluid leak at body joint | Visible material seeping from connector seams |
|---|---|
| Pressure instability | Erratic pressure or inability to build full pressure |
| Visible o‑ring damage | Flattened, cracked, hardened, or swollen seals during inspection |
The 0533930 o‑ring kit is designed for the following Titan sprayer model. Always verify with your machine's parts diagram.

When replacing body connector o‑rings, inspect or replace these related components.
If the regulator is being serviced, consider a full seal kit for the pressure control section.
Inspect the manifold sealing surfaces for nicks, corrosion, or debris.
Bolts or screws that hold the connector together; check for proper torque.
