Supplier's note

  1. Technical Breakthroughs:

    • The ball check valve design minimizes grease leakage under high pressure.
    • Zinc/Chrome plating provides 20% better corrosion resistance than uncoated steel.
    • Precision threading ensures a 15% tighter seal compared to industry standards.
  2. Optimal Version Selection:

    • Base Model: Ideal for standard automotive maintenance (e.g., truck transmissions) where medium pressure (≤3000 PSI) is sufficient.
    • Advanced Model: Suited for industrial machinery (e.g., mining equipment) requiring corrosion resistance and higher pressure tolerance.
    • Pro Model: Best for extreme applications like offshore drilling or aerospace, where ultra-high pressure (6000 PSI) and chemical resistance are critical.

With the Pro Model’s duplex stainless steel, you can handle abrasive fluids while maintaining structural integrity. Pair its precision valve with high-viscosity grease for seamless lubrication in confined spaces.
