Compatible Machines / Systems
The 116514 nut is relevant for systems that include a regulator module and specify this part number in their parts list or schematic. Typical use‑cases include:
- Graco air‑control or air‑panel assemblies for spray or proportioning equipment which list “NUT, regulator” as 116514 in parts documents. :contentReference[oaicite:7]{index=7}
- Sprayers, proportioners, or pump systems where regulator units are used for air supply control and must be securely mounted.
- Any Graco equipment requiring regulator mounting hardware — especially when replacing or servicing regulators.
Note: Because this is a hardware part (nut), its usefulness depends on correct matching with the regulator housing/thread specification. Always verify your machine’s parts diagram before ordering. :contentReference[oaicite:8]{index=8}
When & Why Replace 116514?
- If the existing regulator nut is damaged, cross‑threaded, worn, or missing — replacement ensures regulator is properly secured.
- During maintenance — if regulator assembly is disassembled (e.g. to service or replace regulator), replacing hardware can prevent leaks or loosening under vibration/pressure.
- When upgrading or re‑assembling regulator modules — using genuine 116514 nut ensures correct fit and alignment per manufacturer design.
