Description:

Features and Benefits:

  • Drawn over mandrel (DOM) pressure cylinder for a smoother surface and less resistance, resulting in increased service life
  • O-ring provides constant pressure to the inner tube and makes the valve less susceptible to dirt, wear, and fatigue leading to longer service life
  • Piston seal adjusts as it wears to maintain a tight seal between the piston and pressure tube. This minimizes leak paths for a longer, more consistent, product life.
  • Super-finished chromed piston rod inhibits corrosion and provides a more consistent wear surface
