Chemfluor® Conductive PFA Fluoropolymer Smooth Inner Tube
EPDM Rubber Cover

Features and Benefits
  • Electrostatic dissipating conductive inner tube
  • Improved I.D. surface finish
  • Excellent bend radius
  • Increased maximum lengths up to 100 ft.
  • CTLCT is manufactured to have a maximum resistance of 106 Ω when inducing a charge of 500 volts D.C.
  • Autoclavable
  • Imparts no taste or odors
Note:
Extended Service Life Tip:
Flexible Components Suggest using full-length anti-kink armor casing or at least 16" to 24" long anti-kink cuffs see Hose Cover Options at each fitting end to help reduce the strain on the crimp collar and fittings in high load installations.
Prolonged service at elevated temperature will reduce total service life.

Pressure Rating

N/A Burst Pressure ratings at ambient 70ºF (21ºC). See applicable notes below on vacuum/pressure ratings at temperatures other than ambient.
Working Pressure is given @ 70ºF; Decrease working pressure 1% for every 2ºF above 212ºF.
Vacuum Rating is given @ 70ºF; Decrease vacuum rating 1% for every 2ºF above 212ºF. For 1-1/2'' and 2'' sizes, vacuum rating decreases when installed less than 2X min. Bend radius.
Flare-Thru fittings are pressure rated. Not rated for vacuum service.
Extended Service Life Tip: Flexible Components Suggest using full-length anti-kink armor casing or at least 16" to 24" long anti-kink cuffs see Hose Cover Options at each fitting end to help reduce the strain on the crimp collar and fittings in high load installations.
Prolonged service at elevated temperature will reduce total service life.

  • 1 Working Pressure is given @ 70ºF; Decrease working pressure 1% for every 2ºF above 212ºF.
  • 2 Burst Pressure ratings at ambient 70ºF (21ºC). See applicable notes below on vacuum/pressure ratings at temperatures other than ambient.
  • 3 Vacuum Rating is given @ 70ºF; Decrease vacuum rating 1% for every 2ºF above 212ºF. For 1-1/2'' and 2'' sizes, vacuum rating decreases when installed less than 2X min. Bend radius.
