Smooth Chemfluor® PTFE Fluoropolymer Smooth Inner Tube
304 Stainless Steel High Tensile Strength Braid

Features and Benefits
  • Greater wall thickness of Chemfluor® PTFE tube
    -Up lo 33% thicker than most competing products (tube wall .040 minimum)
    -Superior kink resistance
    -Improved vacuum ratings
    -Better damage resistance
  • Neutral to taste, color and odor
  • Non-stick, non-contaminating
  • Cleans easily -- steam, detergent or caustic
  • Can be autoclaved
  • Full ID sizes
    -Greater flow rate per given size
    -Less pressure drop through fitting area than hoses with tube size ID
Note:
Extended Service Life Tip:
All 3/4", 1", and 1-1/2" TS/TB/TD/TDB assemblies 36" and longer are strongly recommended to use full-length anti-kink casing to help prevent potential kinking and/or liner vacuum collapse

Pressure Rating

N/A Burst Pressure 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 350ºF
Vacuum Rating is given @ 70ºF; Decrease vacuum rating 1% for every 2ºF above 350ºF. 1-1/2" size (TD, TDB) vacuum rating decreases when installed less than 2X min. bend radius.
Extended Service Life Tip: All 3/4". 1". and 1-1/2" TS/TB/TD/TDB assemblies 36" and longer are strongly recommended to use full-length anti-kink casing to help prevent potential kinking and/or liner vacuum collapse.

  • 1 Working Pressure is given @ 70ºF; Decrease working pressure 1% for every 2ºF above 350ºF
  • 2 Burst Pressure 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 350ºF. 1-1/2" size (TD, TDB) vacuum rating decreases when installed less than 2X min. bend radius.
