The Fuji Spray 2098 kit supplies the wearable components you’ll need to service the newer bottom-feed cup used on the Fuji 2095 1-quart assembly. These parts are consumables—replacing them at the first sign of wear helps avoid leaks, pressure loss, and messy cleanups.\n\n\u003ch3\u003eHow do these parts stop paint from backing up into the gun?\u003c\/h3\u003e\n\u003cp\u003eThe diaphragms, gaskets, and pressure tubes with check valves work together to isolate fluid from the air path. The diaphragm creates a flexible barrier; gaskets ensure a tight seal between mating surfaces; the pressure tube and check valve let pressurizing air enter the cup while blocking liquid from returning. Together they reduce the risk of paint entering the turbine or air supply.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDiaphragms flex to accommodate pressure changes without leaking.\u003c\/li\u003e\n  \u003cli\u003eGaskets maintain a consistent seal at cup joints and lid interfaces.\u003c\/li\u003e\n  \u003cli\u003ePressure tubes with check valves allow one-way airflow into the cup only.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat exactly comes in the 2098 kit and what are the parts made of?\u003c\/h3\u003e\n\u003cp\u003eThis kit includes nine pieces: three diaphragms, three gaskets, and three pressure tubes fitted with check valves—sufficient for multiple service cycles.
