O-Ring for SprayTech EP2105 / EP2205 Airless Sprayers
The 9871056 O‑Ring is an OEM replacement seal designed for the fluid section or hydraulic connections of SprayTech EP2105 and EP2205 airless sprayers. It is typically used to seal static joints between pump housing sections, valve retainers, or fitting connections, preventing paint leaks and maintaining system pressure.
Over time, O‑rings can become hardened, cracked, or compressed (taking a permanent set), leading to external leaks, pressure loss, or air ingestion into the fluid system. Replacing a worn or damaged O‑ring with the 9871056 restores a reliable, leak‑tight seal and prevents further damage to surrounding components.
