Titan 221-012 Viton O-Ring
OEM Titan Sealing Component
Titan 221-012 Viton O-Ring is a genuine OEM fluoroelastomer seal used in the prime/spray valve assembly and fluid section of compatible Titan airless sprayers, providing excellent chemical resistance against solvents, paints, and coatings while maintaining a leak-tight seal under high pressure.
Compatibility Overview
Replace if the O-ring is hardened, cracked, flattened, or if fluid leaks, air ingestion, loss of prime, or pressure instability occurs.

Titan 221-012 Viton O-Ring for Prime/Spray Valve and Fluid Section Service
Titan 221-012 is a genuine OEM Viton (fluoroelastomer) O-ring engineered to provide a high-performance seal in the prime/spray valve assembly and fluid section of compatible Titan airless sprayers. Official Titan parts references identify it as the "O-Ring, Viton, housing" for models including the RentSpray 700, Impact 400, and 660 ix. This precision O-ring sits inside the prime/spray valve assembly, creating a critical seal between the valve and the pump block. Viton material provides excellent chemical resistance against aggressive solvents, paints, thinners, and coatings, as well as high-temperature durability that would damage standard rubber O-rings.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine Titan OEM Viton O-ring for compatible airless sprayers. Used in the prime/spray valve assembly and fluid section to seal fluid passages, pump housings, and valve assemblies. |
| Function | Provides a tight seal between the prime/spray valve and the pump block. Prevents fluid leaks under pressure, stops air ingestion that causes loss of prime, and maintains pressure stability. Viton material resists degradation from aggressive solvents, paints, thinners, and high temperatures. |
| Specifications | Material: Viton (fluoroelastomer / FKM). Sold individually. |
| Compatible Airless Sprayers | 330, 340, 440, 440I, 440IX, 440XC, 540IX, 550XC, 640I, 640IX, 660XC, 690GXC, 740I, 740IX, 840I, 840IX, 1100XC, 1140I, 1140IX, 1200GXC. |
| Compatible Epic / Impact Models | Epic 440E, 447EX, 447HPX, 660EX, 660HPX, 690GX, 1200HPG; Impact 410, 440, 640, 640 I and IA. |
| Compatible RentSpray / PowrLiner / Other | RentSpray 450, 500, 600, 700, Plus; PowrLiner 2800, 3100; PowrTex 1200SF; Helix LP; Performer 640I, 1140IX; Advantage GPX 220; ProFinish TS40, TS50; ProMark II. |
| OEM Part Number | 221-012 Viton O-Ring. |
| Replacement Indicators | Hardening or loss of elasticity (O-ring feels brittle or no longer rebounds); visible cracks or nicks creating a leak path; flattening or compression set causing bypass; fluid leaks, air ingestion, loss of prime, or pressure instability. |
| Related Parts Commonly Serviced Together | Prime/spray valve assembly (700-258), gasket (700-537), PTFE O-ring (222-012), valve stem O-ring (700-721). |
| Why Genuine OEM | Exact dimensions and Viton material composition ensure proper fit and sealing effectiveness under high pressure. A low quality or incorrect O-ring may fail to seal, allow fluid leaks, or degrade prematurely when exposed to aggressive solvents. |
When replacing the 221-012 O-ring, always lubricate the new O-ring with a compatible grease or coating material before installation. Inspect the groove and mating surfaces for scratches or debris. Do not over-stretch the O-ring during fitting. Always replace O-rings when servicing the prime/spray valve to ensure a proper seal.
