(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 tubing.*

ALTAFLUOR® 550 Tubing is resistant to many commonly used industrial fluids and gasses, 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, ALTAFLUOR® 550 tubing and pipe products are 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 PVDF tubing is available in standard and metric sizes. ALTAFLUOR® 550 PVDF tubing is compatible with most standard fittings (not suitable for use with flare-type fittings).

ALTAFLUOR® 550 PVDF pipe is available upon request.
