The Graco 239914 Prime/Drain Valve Repair Kit restores proper pressure relief and drainage in your airless sprayer. Over time, drain valves wear and can start to leak fluid back into the paint container, or fail to relieve pressure when needed. Replacing the worn valve stops leaks and ensures the sprayer primes and drains correctly. This kit includes thread sealing paste for secure fitting. It fits a wide range of Graco airless sprayer models, including popular mid‑range and pro series units. Keep this repair kit on hand to reduce downtime and maintain consistent performance job after job.
