Hydro‑Force Sprayer Lid NA0812 – White Screw Cap for Revolution Inline Sprayer
This genuine Hydro‑Force Sprayer Lid (official part number NA0812, also supplied as
1685‑0378) is the correct white screw cap positioned directly beneath the
Adjustable Dilution Rate Valve on the Hydro‑Force Revolution Inline Sprayer.
It forms the primary upper seal on the chemical bottle and supports the dilution valve assembly.
Inside this lid sits the
Hydro‑Force Cap Liner (1676‑2128), which provides the internal airtight seal.
Both components work together to maintain correct chemical draw and prevent air leaks.
A damaged or worn lid can cause loss of prime, air draw, chemical leaks and inconsistent spray patterns.
Replacing it restores a secure seal and keeps your Revolution sprayer performing reliably.
