Titan 0294788 Belleville Washer Kit
OEM SprayTech Pressure Control Component
Titan 0294788 Belleville Washer Kit is a genuine OEM set of conical spring washers for compatible SprayTech airless sprayers. Confirmed in the official EP2300 manual for the dump valve assembly, these washers provide consistent tension and compensate for wear in the pressure control stack.
Compatibility
Replace Belleville washers as a complete set. Inspect the piston rod and packing nut for scoring or wear. Lubricate washers with pump oil during reassembly. Follow the correct stacking orientation per your service manual.

Titan 0294788 Belleville Washer Kit for SprayTech Airless Sprayers
Titan 0294788 is a genuine OEM Belleville washer kit containing conical spring washers that provide precise preload and compensation for thermal expansion and wear in the pump's pressure control assembly. These washers are installed in the dump valve assembly of compatible SprayTech EP-series sprayers. Over time, Belleville washers can lose their spring rate due to metal fatigue, corrosion, or permanent flattening. A weakened stack results in inadequate sealing force, causing pressure loss, leakage past packings, or difficulty building prime. Replacing the entire kit restores factory-spec spring tension and extends pump life.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine OEM Belleville washer kit for SprayTech EP-series sprayers. Conical spring washers provide precise preload in the dump valve assembly, compensating for wear and thermal expansion. |
| Function | Maintains packing tension (keeps packings compressed against piston rod); compensates for wear (automatically adjusts as packings wear down); absorbs vibration (dampens pressure pulses); provides consistent preload (delivers precise spring force regardless of temperature). |
| Compatible Models | SprayTech Airless EP2300; EP2300 SE; EP2400; EP2510. Always verify with your machine's parts diagram for exact placement and quantity. |
| OEM Part Number | 0294788 Belleville Washer Kit. |
| Replacement Indicators | Pressure loss or surging (pump fails to maintain steady pressure); packing leakage (paint leaks past rod even after tightening packing nut); loss of prime (difficulty building pressure); flattened or cracked washers (visible deformation or breakage). |
| Related Parts Commonly Serviced Together | Packing set and seals (worn packings are often the root cause); piston rod and plunger (scored or corroded rod will damage new packings); packing nut and retainer (check for damaged threads). |
| Why Genuine OEM | Correct dimensions and spring rate ensure proper preload and pump performance. Belleville washers lose spring force over time even without visible damage. Always install new washers from the kit to ensure correct preload. |
Service guidance: Replace Belleville washers as a complete set. Inspect the piston rod and packing nut for scoring or wear. Lubricate washers with pump oil during reassembly. Always follow the correct stacking orientation (alternating or nested) per your service manual. Belleville washers lose spring force over time even without visible damage; always install new washers from the kit to ensure correct preload and pump performance. Always relieve system pressure and disconnect power before servicing.
