Maximum Working Pressure (psig)


  • Using the same base linerar low-density polyethylene (LDDPE) as the E-Series tubing, PEFR tubing has the following advantages:
    • Resistant to environmental stress cracking exceeding that of ordinary polyethylene tubing as measured by ASTM D-1693 (10% IGEPAL)
    • The recommended operating temperature range for service at rated pressures with compatible fluids is -85°F to 150°F (-65°C to 66°C)

Use with The Following Parker Fittings

  • Compression
  • Compress-Align
  • Hi-Duty
  • Fast & Tite
  • Flow Control
  • Prestolok Brass
  • Dubl-Barb

A tube support should be used with this tubing for maximum holding power where end loading, vibration or pressure spikes may occur. See compatibility chart for plastic tubing with fittings.
