• The following PEEK fitting tools can be used to meet needs where applicable:
  • Part number 700002875 for the "NUT EXTENDER, FLANGELESS, LONG"
  • Part number 700003123 for the "NUT EXTENDER, FLANGELESS, SHORT"

  • Part number 410001941 for the "NUT EXTENDER, FLANGELESS, RIGHT ANGLE"
    • This part is useful for accessing fittings in hard to reach spaces.
      

ADDITIONAL INFORMATION

Do not over-tighten the fittings.

• Over tightening the fittings can damage the threading of the PEEK fitting.
• Finger tighten first, then finish using the nut extender adding a quarter turn to the fitting.

Another option would be to use metal fittings rather than PEEK to hold the tubing better.
