Chemfluor®FEP Fluoropolymer Smooth Inner Tube
EPDM Rubber Cover

Features and Benefits
  • Unexcelled chemical resistance
  • Full vacuum rated
  • Durable, kink resistant, with no external wire reinforcement to potentially fray
  • Easy-to-clean, non-stick smooth tube for assured sterility
  • Can be cleaned with steam, caustics, solvents or other cleaning agents
  • Resistant to chemicals, ozone and abrasion
Note:
Extended Life Service Tip:
Flexible Components suggests using full-length anti-kink armor casing or at least 16'' to 24" long anti-kink cuffs at each fitting end to help reduce the strain on the crimp collar and fittings in high toad installations. Prolonged service at elevated temperatures will reduce total service life.

Pressure Rating

N/A Burst Pressure rating at ambient 70ºF (21ºC). See applicable notes 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 1-1/4'' and larger sizes, vacuum rating decreases when installed less than 2X min. bend radius
Flare thru fitting are pressure rated only. Not rated for vacuum service
Extended Service Life Tip: Flexible Components suggests using full-length anti-kink armor casing or at least 16'' to 24" long anti-kink cuffs at each fitting end to help reduce the strain on the crimp collar and fittings in high toad installations. Prolonged service at elevated temperatures will reduce total service life.

  • 1 Working Pressure is given @ 70ºF; Decrease working pressure 1% for every 2ºF above 212ºF
  • 2 Burst Pressure rating at ambient 70ºF (21ºC). See applicable notes 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 1-1/4'' and larger sizes, vacuum rating decreases when installed less than 2X min. bend radius.
