The 700-159 Pressure Control Knob is a direct replacement for the original Titan 507740 knob and is compatible with a wide range of airless sprayer models. This knob connects to the pressure control mechanism, allowing the operator to adjust spray pressure according to the requirements of the coating and application.
Over time, pressure control knobs can become stripped, cracked, or worn from frequent use. A damaged knob can make pressure adjustment difficult or impossible, leading to improper spraying pressure and poor finish quality. Replacing a worn or broken knob with this new component restores precise pressure control and operator convenience.

|---|---|
| Fine-tuning | Enables precise pressure setting for different coatings |
| User interface | Provides tactile control for pressure regulation |
| Stripped knob | Knob spins freely without engaging the pressure control mechanism |
|---|---|
| Cracked or broken | Visible cracks or missing pieces prevent proper grip/use |
| Hard to turn | Knob is difficult to rotate due to internal damage |
| Missing knob | Knob has fallen off or been lost during operation |
