Titan part 252279 is an inlet valve housing assembly designed for use on PowrLiner 5500 and Elite 5500 sprayers. This assembly houses the inlet valve components, directing material from the suction hose into the fluid section while preventing backflow. Replacing a cracked, worn, or damaged housing restores proper material intake, eliminates air leaks, and ensures reliable priming.

The Titan 252279 Inlet Valve Housing Assembly is a genuine OEM component that forms the entry point for material entering the fluid section of PowrLiner 5500 and Elite 5500 sprayers. It houses the inlet valve seat, ball, and spring, ensuring one‑way flow from the suction hose into the pump cylinder. Precision‑cast for a perfect seal, this housing prevents air ingestion and material backflow.
Over time, the inlet valve housing can become cracked from overtightening or impact, or the internal sealing surfaces may wear. A damaged housing allows air to enter the system, causing loss of prime, erratic spray, and reduced output. Replacing with the correct 252279 assembly restores a tight seal, eliminates air ingestion, and ensures reliable priming and consistent material delivery.

When replacing the inlet valve housing, inspect these related components for wear or damage.
The housing holds the inlet valve; replace the seat and ball as a set during rebuild.
Clean or replace the strainer to prevent debris from entering the new housing.
Check the hose end and fitting for damage that may have caused overtightening.
