The 0508330 Knob Label is an OEM replacement decal or insert designed for the pressure control knob on a wide range of SprayTech airless sprayers. It displays the pressure scale (typically in PSI or numerical settings) and directional icons, allowing the operator to accurately adjust output pressure for different materials and tip sizes.
Over time, knob labels can wear off due to repeated handling, chemical exposure from paint solvents, or UV fading. A missing or illegible label makes it difficult to set the correct pressure, leading to poor finish quality, tip clogging, or excessive overspray. Replacing the label with the 0508330 restores clear pressure markings and professional appearance.

When replacing the knob label, these related components are often inspected or replaced at the same time.
If the knob itself is cracked or worn, replace it along with the label.
For sprayers with multiple decals, inspect other labels for wear.
Use a mild solvent to clean the knob surface before applying the new label.
