Description

Visiflon is a fully convoluted PTFE lined hose. Used in applications where extreme flexibility is required and convoluted bore will not be a disadvantage. Available with stainless steel wire braid.

HOSE BORE SIZE RANGE –
3/8” (10MM) UP TO 11/4” (50MM)

HOSE LENGTHS –
UP TO 1”, 70 FEET (20 METRES). 11/4”, 50 FEET (15 METRES)

TEMPERATURE LIMITS –
100°F (-73°C) TO 450°F (+230°C)

WORKING PRESSURE RATINGS – (stainless steel braided hose)
3/8” (10MM) = 870 PSI (60 BAR) TO 11/4” (32MM) = 25 BAR (360 PSI)

VACUUM LIMITATIONS – (stainless steel braided hose)
USABLE AT VACUUM TO -0.9 BAR FOR ALL SIZES, UP TO 266°F (130°C)

END FITTING OPTIONS – Standard design only for:
BSPT AND NPT MALE AND FEMALE, BSP AND NPSM 60° CONE SEAT AND FLAT SEAT FEMALE UNIONS, JIC THREADED MALE AND FEMALE FITTINGS, STANDPIPE FITTINGS AND MANY MORE

ALTERNATIVE DESIGN OPTIONS (to special order) –

  • ORANGE POLYPROPYLENE YARN BRAID
  • BLACK, ANTI-STATIC PTFE LINER TUBE

Specifications

Specifications listed below are for non-antistatic grades. For anti-static (AS) grades the specifications are all the same, except that “AS” is added to the grade
reference, and the part number reads “-110-” in place of “-100-”.

*Visiflon Hose assemblies require that the convolutions at the ends of the hose are opened out to accept either Hydraulic or PTFE Tail end fittings.

TEMPERATURES AND PRESSURES

  • Visiflon tube only (TO) grades - The MWP listed above applies up to a maximum temperature of 212˚F (100˚C).
  • Visiflon stainless steel (SS) grades - The MWP listed above should be reduced by 1% for each 1.8˚F above 266˚F up to a maximum of 445˚F (1% for each
    1˚C above 130˚C up to a maximum of 230˚C).
  • Visiflon polypropylene (PB) Grades - The MWP listed should be reduced by 5% for each1.8˚F above 176˚F to 212˚F (5% for each 1˚C above 80˚C up to a
    maximum of 100˚C).

VACUUM RESISTANCE
Visiflon SS grades are usable at vacuum to -0.9 bar up to 266˚F (130˚C). Visiflon TO and PB grades are vacuum resistant to -0.9 bar up to 176˚F (80˚C).

FLOW RATES
The internal convolutions restrict flow rates due to turbulent flow, and may also cause a whistling noise when gases are passed through. For any applications
where this may be a problem, the alternative Aflex Hose products Hyperline FX or Corroline+ would provide a solution.
