Titan part 221-012 is a Viton fluoroelastomer O‑ring used to seal fluid passages, pump housings, and valve assemblies on a wide range of compatible sprayers. Viton provides excellent chemical resistance against solvents, paints, and coatings, as well as high-temperature durability. Replace when the original O‑ring is hardened, cracked, or leaking.

The Titan 221-012 Viton O‑ring is a high‑performance sealing component made from fluoroelastomer (FKM). It is designed to resist degradation from aggressive solvents, paints, thinners, and high temperatures that would damage standard rubber O‑rings. This O‑ring is used in pump fluid sections, valve housings, and manifold connections across dozens of sprayer models.
A worn, flattened, or hardened O‑ring will cause fluid leaks, air ingestion, loss of prime, or pressure instability. Replacing with a genuine Viton O‑ring restores leak‑tight sealing and ensures compatibility with chemical‑based coatings.
| Fluid sealing | Prevents leaks of paint, solvent, or water under pressure |
|---|---|
| Chemical resistance | Viton withstands aggressive coatings that damage standard rubber |
| Temperature stability | Maintains seal integrity at elevated operating temperatures |
| Hardening / loss of elasticity | O‑ring feels brittle or no longer rebounds after compression |
|---|---|
| Cracks or nicks | Visible damage that creates a leak path |
| Flattening / compression set | O‑ring no longer fills the groove, causing bypass |
Titan part 221-012 is a direct replacement for the Viton O‑ring used in the following sprayers. Always confirm size and location using your equipment's parts diagram.

When replacing a worn O‑ring, inspect these associated sealing components.
Used with O‑rings in high‑pressure or dynamic applications to prevent extrusion.
Scratches, corrosion, or debris in the O‑ring groove will cause premature failure of the new seal.
Worn or damaged metal surfaces can compromise O‑ring sealing.
