Why Use This Valve

Installing the Graco 15B565 ensures precise control over flow in critical systems like Fusion‑AP guns or texture sprayers. A high-quality OEM ball valve maintains a positive seal, reducing fluid leaks, preventing air bleed, and preserving system integrity even under repeated cycles.

  • If the valve feels loose or leaks when actuated, replace it with the correct OEM part.
  • During installation, use Teflon tape or approved sealant on threads to ensure a tight, leak-free fit.
  • Cycle the valve a few times after installing to check for smooth operation and reliable sealing.
