• Compatible Models：for Graco Husky 1050 Pump，Directly replaces your original 25A857 pump repair kit with no modifications needed.
• PTFE Seat: Features exceptional corrosion resistance and high/low temperature tolerance, suitable for transporting various fluids, solvents, and strong chemical media. Resists deformation and aging, offering over three times the service life compared to standard rubber seats.
• Acetal Ball Valve: High hardness and excellent wear resistance ensure stable sealing performance. Effectively reduces internal leakage risks during fluid transfer, maintains stable pump pressure, and minimizes flow rate decline caused by valve failures.
• TPE (Thermoplastic Elastomer) Diaphragm: Combines rubber's high elasticity with plastic's weather resistance. Features strong tear resistance and fatigue endurance, withstands high-frequency reciprocating motion, and accommodates fluids of varying viscosities. Prevents fluid leakage and equipment damage caused by diaphragm rupture.
• Kit includes: 4 PTFE valve seats with 8 PTFE O-rings, 4 polyoxymethylene balls, and 2 Hytrel diaphragms. This integrated kit significantly optimizes pump sealing performance and fluid transfer efficiency, minimizing pressure loss and flow instability caused by component wear.
