  • Stack height value in technical data table includes seal retainer plate.
  • This installation requires a seal retainer plate and seal kit which are purchased separately. See "Related Accessories" section.
  • For detailed information regarding the cartridges contained in this assembly, click on the models codes shown in the Included Components tab.
  • Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
