Part 765-087 is a nylon lock nut with integral strain relief designed to secure electrical cables and cords at entry points on compatible sprayers. It prevents cable pull-through, protects wires from abrasion, and provides vibration resistance. Replacing a damaged or missing strain relief nut restores proper cable protection and helps prevent electrical faults.

The 765-087 Nylon Lock Nut with Integral Strain Relief is a specialized fastener used to secure power cords and electrical cables where they enter control boxes, motors, or other components. The nylon construction provides electrical insulation and corrosion resistance, while the integrated strain relief grips the cable to prevent pull-through and protect internal connections from mechanical stress.
Over time, these nuts can crack from UV exposure, become brittle, or lose their gripping ability. A damaged strain relief nut may allow the cable to pull loose, causing intermittent electrical connections, short circuits, or complete power failure. Replacing with genuine part 765-087 restores proper cable protection and ensures reliable electrical operation.
| Cable securing | Holds power cord firmly at entry point to prevent pull-through |
|---|---|
| Strain relief | Absorbs tension so internal wire connections are not stressed |
| Abrasion protection | Prevents cable insulation from chafing against sharp metal edges |
| Cracks / damage | Visible cracks, breaks, or deformation of the nylon body |
|---|---|
| Loss of grip | Cable can be pulled through the nut easily |
| Missing nut | Strain relief nut is lost or missing from assembly |
| Intermittent power | Loose cable connection causing electrical faults |
