(PVDF FLEX) Altafluor 550

ALTAFLUOR® 550 PVDF Flex Tubing

PVDF FLEX (polyvinylidene fluoride – commonly known by the trade name KYNAR FLEX®) is a more flexible version of PVDF. ALTAFLUOR® 550 Tubing is resistant to many commonly used industrial fluids and gases, including ozone, and does not support the growth of fungi. For this reason ALTAFLUOR® 550 tubing is preferred for water disinfecting processes involving ozone such as aquarium, spa, pool and agriculture.

Additionally, it is ideal for applications with exposure to less aggressive chemicals and lower temperature exposure (over FEP or PFA) or those requiring low extractable levels.

ALTAFLUOR® 550 is available in many standard sizes available to ship from stock.

Custom sizes are available upon request.* ALTAFLUOR® 550 tubing is compatible with most standard fittings (not suitable for use with flare fittings).
