Compatible Assemblies for the Graco 114830 Flat Washer
- Any Graco spray-pump or fluid-handling assembly where the parts diagram lists 114830 – Washer, Flat (e.g. Monark-type airless spray pumps, fluid regulators, mounting brackets). ([Graco manual](#))
- Bolt- and nut-based joints — such as fluid-fitting mounts, housing covers, pump body assemblies — needing load distribution and surface protection under fasteners.
Product Overview
The 114830 Flat Washer is a genuine OEM washer from Graco, intended to sit under bolt heads or nuts to distribute load, protect mounting surfaces and ensure secure, stable fastening. It helps prevent bolt-head or nut from digging into or damaging equipment housing or fittings, and ensures consistent tightness — important in high-pressure or vibration-prone equipment.
Key features include:
- OEM-specified flat washer — correct dimensions and compatibility for Graco assemblies.
- Load-distribution under bolt / nut — reduces risk of surface deformation or cracking under pressure/tightening.
- Ensures secure, stable fastening — especially important where fluid pressure, vibration or mechanical stress exists (e.g. pumps, fittings, housings).
Why Use This Washer?
Using the OEM-specified washer (part number 114830) ensures that bolts or nuts have the correct bearing surface, load distribution and fit as designed by the manufacturer. Substituting with a generic or incorrect washer may result in improper load distribution — risking leaks, cracked housings, loose fittings or premature wear. OEM washer helps maintain long-term reliability and structural integrity of your Graco equipment.
Frequently Asked Questions
Replace when washer shows signs of wear, deformation, corrosion, or if you disassemble and reassemble the joint — especially if bolt/nut is reused, to ensure proper bearing and sealing.
While a generic flat washer might seem similar, OEM washer ensures correct diameter, thickness and material compatibility — which is important for maintaining sealing, structural integrity and avoiding damage over time. For best results, use the Graco-specified 114830 washer.
