Because official documentation for part number 112830 is limited, users are advised to verify their specific model’s parts manual or exploded diagram before purchasing. No comprehensive model list is publicly provided.

Use with any Graco machine or pump assembly where the original parts diagram lists **112830** as the required packing O‑ring.
If your model’s manual does not list 112830, this may not be the correct part — confirm with serial/model and Graco support.

Key Features

OEM genuine part by Graco.
Designed to restore or maintain sealing performance inside fluid/pump housings.
Easy to replace when visible wear, leakage or loss of pressure occurs.
Fits as long as the machine’s manual indicates part number 112830; direct fitment is based on that match.

Installation & Service Tips

Always depressurize the system and follow the manufacturer’s service safety procedures before removal.
Inspect the sealing groove and mating surfaces for wear, debris or damage; clean if needed.
Lightly lubricate the new O‑ring (if specified by your machine’s manual) and install carefully—avoid twisting or stretching the O‑ring during installation.
After installation, reassemble per the manual, restore pressure and check for leaks. If drips or loss of pressure persist, reassess the O‑ring seating and groove condition.

Frequently Asked Questions

If your exact machine model is not explicitly listed for part 112830, you should cross‑check the machine’s exploded parts diagram or service manual for the packing O‑ring call‐out. Confirm whether that call‑out lists 112830 before ordering.

It's generally **not recommended** to reuse an O‑ring once it has been in service, even if it appears intact. O‑rings can flatten, set, or suffer micro‑damage. Replacing with a fresh genuine part ensures better sealing reliability.

Signs include: visible fluid leakage or seepage around the sealed joint, inability to hold system or pump pressure, frequent priming issues (in pump systems), or visible deformation of the existing O‑ring.

Note: Always refer to your equipment’s official parts manual for part verification, and ensure that the correct part is specified for your serial number and machine version.
