Hydra part 441-026 is an O-ring designed to create a leak-proof seal in fluid connections on compatible Hydra M and Hydra Pro Super sprayers. This precision-molded seal prevents fluid bypass and maintains system pressure in critical sealing applications. Replacing a worn, compressed, or damaged O-ring restores proper sealing and prevents costly fluid leaks.

The Hydra 441-026 O-Ring is a precision-molded sealing component used in various fluid connections on compatible Hydra sprayers. Manufactured from high-quality elastomer, it provides excellent resistance to oils, solvents, and pressure while maintaining flexibility for effective sealing.
O-rings are critical for preventing fluid leaks at connection points throughout the sprayer system. Over time, O-rings can become compressed, dried out, cracked, or nicked due to temperature cycling, chemical exposure, or normal wear. A compromised O-ring allows fluid to escape, leading to pressure loss, material waste, and potential damage to surrounding components. Replacing worn O-rings restores system integrity and ensures reliable operation.
| Fluid sealing | Creates a leak-proof barrier between mating components |
|---|---|
| Pressure containment | Helps maintain system operating pressure |
| Contamination prevention | Blocks debris from entering fluid passages |
| Visible leaks | Fluid escaping at connection points |
|---|---|
| Flattened / compressed | O-ring no longer has round cross-section |
| Cracks / cuts | Surface damage compromising the seal |
| Hardened / brittle | Loss of flexibility due to age or chemical exposure |
Hydra part 441-026 is compatible with the following sprayer models. Always verify fitment using the correct parts diagram for your exact model and serial number.
| Model | Component |
