The Y14742001 is a .218" diameter replacement check ball for pressure washer chemical injectors. Inside the injector, the ball sits against a seat in the chemical inlet and acts as a one-way valve: it lifts to let chemical be drawn into the water stream, then seals to keep water from flowing back up the chemical line. When a check ball wears, pits, corrodes, or sticks, it can’t seal properly, which typically shows up as weak or no chemical draw, inconsistent mixing, or water backing up into the chemical container.
The ball is made from 440 stainless steel, a hardened grade that resists wear and holds its round shape longer than softer stainless steels, while still offering good corrosion resistance against soaps, degreasers, and many common cleaning chemicals. Replacing a worn ball is a quick, low-cost way to restore reliable chemical draw without replacing the whole injector.
Key features:
- .218" diameter check ball
- Hardened 440 stainless steel for wear resistance
- Corrosion resistant for use with common cleaning chemicals
- Restores one-way sealing to prevent backflow
