CPI Compression

XD+ Divider Blocks

Designed to perform at higher pressures, XD+ Divider Blocks are built tough to keep your compressor running, reduce the size of lubricator boxes and maximize lubrication system efficiency.


  • Symmetric element design adds mass around the piston for improved performance at higher pressures by reducing piston bore warping and expansion
  • Improved piston-to-bore geometry for consistent oil output and longer product life
  • Improved overall sealing with precision CPI custom 1/8 ORB (O-Ring Boss) port geometry
  • Dual inlet ports on top and bottom of divider block assembly for added flexibility
  • Complete assembly standard with O-ring seals eliminates leakage and need for sealant
  • Each assembly comes standard with Custom ORB inlet tube fitting and ¼” NPT adapter fitting
  • Improved corrosion resistance with all components nickel plated
  • All base plate assemblies feature internal check valves for added performance protection
  • Standard O-ring seals are VITON® O-Rings (FKM) for improved chemical and heat resistance
  • Each divider block assembly is easily configured to your specific lubrication needs


  • Extreme performance for applications up to 8,000 PSI (551 BAR)
