Fuji Spray bottom-feed cup parts kit for 2095 1Qt — 9-piece diaphragms, gaskets & check-valve tubes

Fuji Spray 2098 is a 9-piece replacement kit of diaphragms, gaskets, and pressure tubes designed to restore reliable sealing and anti-backup performance in newer Fuji 2095 bottom-feed cup assemblies.

If your Fuji 2095 1Qt cup assembly is showing signs of leaks, paint backup, or loss of cup pressure, the 2098 parts kit supplies the wearable components you need to get the cup functioning like new again. This compact set contains three diaphragms, three gaskets, and three pressure tubes with check valves, each part engineered to work together to stop paint from seeping into the pressurization path and to maintain consistent airflow for smooth spraying.

How will these parts stop paint backup in my Fuji 2095 cup?

Each component in the kit focuses on a specific sealing or flow function. The diaphragms flex to maintain pressure without letting fluid pass, gaskets create a tight barrier where cup meets lid, and the pressure tubes with check valves keep air flowing while blocking liquid return.

• Diaphragms flex to maintain air pressure without allowing paint through.
• Gaskets form the sealing surfaces between cup parts to prevent leaks.
• Pressure tubes have one-way check valves that prevent fluid from flowing back.

Which Fuji cup assemblies are compatible with this kit?

This kit is specifically made for the Fuji 2095 1Qt bottom-feed cup assembly and will fit the newer cup design. It is not compatible with the older 2042 cup assembly, so verify your cup model before purchasing to avoid fitment issues.

• Compatible only with Fuji 2095 1Qt cup assembly.
• Not compatible with Fuji 2042 cup assembly—see part 2039 for that kit.
• Intended as wearable consumable replacements for routine maintenance.

How often should I replace these parts to maintain spray performance?

Replacement intervals depend on paint types used, cleaning frequency, and operating conditions. As a guideline, inspect seals and diaphragms whenever you notice decreased pressure, leaking, or spraying inconsistencies; carrying this 9-piece kit helps you swap worn parts quickly to minimize downtime.

• Check parts during routine cup cleaning and whenever performance dips.
• Replace diaphragms and gaskets if hardened, cracked, or deformed.
• Swap pressure tubes if check valves stick or if you observe fluid in the air path.

Who is this kit for? The Fuji Spray 2098 Bottom Feed Cup Parts Kit is aimed at professional painters, body shop technicians, sprayer rental shops, and dedicated DIYers who rely on Fuji 2095 1Qt bottom-feed systems and want a fast, reliable way to maintain cup sealing and pressure integrity. If you service multiple sprayers or run extended jobs with repeated cup changes, keeping this kit on hand reduces interruptions and protects your turbine and gun from contamination. Note: if your cup assembly is the older 2042 design, choose part 2039 instead—this 2098 kit fits only the newer 2095 cup design.
