SprayTech part 0277425 is a Viton o-ring used to create a leak-proof seal between fluid handling components on compatible sprayers. Viton material provides excellent chemical resistance and durability, making it ideal for use with paints, solvents, and aggressive coatings. A worn, hardened, or damaged o-ring can cause fluid leaks, pressure loss, and air ingestion into the system. Replacing with this genuine SprayTech Viton o-ring restores proper sealing and reliable operation on CS 55 and CS 5100 models.

The 0277425 Viton O-Ring is a high-performance sealing component used in critical fluid pathways of SprayTech CS series sprayers. Manufactured from Viton® fluoroelastomer, this o-ring offers exceptional resistance to paints, solvents, thinners, and aggressive chemicals commonly used in professional coating applications.
O-rings create positive seals between mating components such as pump housings, valve assemblies, fluid manifolds, and fittings. Over time, o-rings can harden, crack, compress, or lose elasticity due to chemical exposure, heat, and age. A compromised o-ring can lead to external leaks, air ingestion, pressure loss, and erratic spray performance. Replacing worn o-rings with this genuine Viton component restores leak-free operation and ensures system integrity.
| Fluid sealing | Prevents leaks between mating fluid components |
|---|---|
| Pressure containment | Maintains system pressure by sealing high-pressure connections |
| Contamination barrier | Prevents air and debris from entering fluid path |
| Chemical resistance | Viton material withstands paints, solvents, and aggressive coatings |
| Fluid leakage | Visible material escaping from sealed connection |
|---|---|
| Hardened / brittle | O-ring has lost elasticity and no longer compresses properly |
| Flattened / compressed | Permanent deformation that prevents proper sealing |
| Cut or nicked | Physical damage from installation or wear |
SprayTech part 0277425 is compatible with the following SprayTech sprayer models. Always confirm fitment using the correct parts diagram for your exact model and revision.
| SprayTech Model | Component |
|---|---|
| SprayTech CS 55 | O-Ring, Viton |
| SprayTech CS 5100 | O-Ring, Viton |
When replacing o-rings, consider inspecting these associated components for wear or damage.
May include multiple o-rings and seals for comprehensive pump service.
Inspect mating surfaces for damage that could affect sealing.
Compatible lubricant helps install o-rings without damage and improves sealing.
