Titan 0551661 is an OEM inlet valve housing with a long tube for the fluid section of compatible Advantage and EPX sprayers. It houses the inlet valve components that regulate paint flow during the intake stroke and prevent reverse flow, ensuring proper material supply to the pump. Titan 662-539 is an SC-6 Plus reversible airless spray tip with a 0.039 inch orifice, 50 degree spray angle, and approximately 10 to 12 inch fan pattern for professional-grade coating application.
| Detail | Technical / Commercial Information |
|---|---|
| Housing Overview | OEM Titan/SprayTECH 0551661 inlet valve housing with long tube. Listed in official Titan parts diagrams for the EPX2355 Fluid Section Assembly (Upright Cart P/N 0551675, item 21) and the Advantage 600 (item 21, "Inlet valve housing, long tube (upright cart)"). |
| Housing Function | Contains the inlet valve assembly that regulates paint flow during the intake stroke. Houses the inlet seat, ball, spring, and cage. Prevents reverse flow and ensures proper material supply to the pump for uninterrupted spraying and uniform finish quality. |
| Housing Compatible Models | Titan Advantage 600 (Upright Cart configuration), SprayTECH EPX2355 (Upright Cart P/N 0551675). Verify fitment against your specific model parts diagram before ordering. |
| Tip Overview | Titan 662-539 SC-6 Plus reversible airless spray tip. 0.039 inch (0.99 mm) orifice, 50 degree spray angle, approximately 10 to 12 inch fan pattern, white color coding. Maximum working pressure 5000 PSI (53.1 MPa). Up to 22% wider fan pattern compared to standard tips. |
| Tip Features | Reversible design for quick clog clearing without disassembly. Tungsten carbide orifice for extended life and consistent film thickness. Fits all Titan and most industry standard spray gun guards. Laser etched markings for quick size identification. |
| Tip Applications | Professional airless spraying for latex, oil-based paints, primers, and other coatings in residential and commercial applications. The 0.039 inch orifice and 50 degree angle are suitable for general purpose spraying with good coverage and flow rate. |
| Common Failure Symptoms | For housing: loss of prime, poor material draw, visible cracks or stripped threads in the housing body, fluid leaks at the inlet connection. For tip: uneven spray pattern, reduced fan width, spitting or dripping from the tip, visible wear or damage to the orifice. |
| Commercial Benefits | Genuine OEM components restore proper material intake and precision spray patterns, maintaining consistent pressure and reliable finish quality while reducing downtime from priming issues and tip clogs. |
The 0551661 Inlet Valve Housing and 662-539 SC-6 Plus Tip are practical service components for contractors maintaining compatible Titan and SprayTECH sprayers. If the pump struggles to draw material, loses prime, or exhibits poor inlet flow, inspect the inlet valve housing for cracks, worn threads, or damaged internal components. When replacing the housing, also inspect the inlet seat, ball, spring, and O-rings, and consider a complete inlet valve rebuild for best results. For the SC-6 Plus tip, replace when the spray pattern becomes uneven, fan width decreases, or finish quality degrades despite proper cleaning and pressure adjustment. Both components are critical for reliable material delivery and consistent finish quality.
