Part 890-114 is a replacement urethane o-ring used in fluid sections and pump assemblies on compatible spray equipment. This o-ring creates a positive seal between components, preventing fluid leaks and maintaining pressure. Urethane material provides excellent abrasion resistance and compatibility with a wide range of coatings. When the original o-ring becomes cut, flattened, or brittle, replacement restores leak-free operation.

The 890-114 urethane o-ring is a direct replacement seal for fluid sections and pump assemblies on Admiral, Commander, and PowrTex 15-1 spray equipment. This o-ring fits into precision grooves to create a leak-proof barrier between mating components, preventing fluid bypass and maintaining consistent pressure. Urethane material offers superior abrasion resistance compared to standard rubber, making it ideal for abrasive coatings and high-wear applications. It also resists swelling and degradation from solvents commonly found in paints and stains. A damaged or worn o-ring can cause pressure loss, erratic spray patterns, or external leaks. Replacing with this urethane o-ring restores proper sealing and extends pump life. Installation requires careful cleaning of the groove and light lubrication. Regular inspection during pump service helps identify o-rings that have taken a set or developed cuts.
| Fluid sealing | Prevents leaks between fluid section components |
|---|---|
| Pressure retention | Maintains system pressure for consistent spraying |
| Abrasion resistance | Urethane material withstands abrasive coatings |
| Visible cuts or nicks | Damage allows fluid bypass |
|---|---|
| Flattened / compressed | O-ring no longer provides adequate sealing force |
| Brittleness | Material has hardened and lost elasticity |
| Fluid leakage | External leaks at sealed joint |

When replacing o-rings, inspect these associated components to ensure proper sealing.
Check for scoring or wear that could damage new o-ring.
Ensure sealing surfaces are clean and free of burrs.
Replace if used in application and worn.
