Altaflo® 550 PVDF Flex Tubing
Flexibility that is preferred for water disinfecting processes
PVDF FLEX (polyvinylidene fluoride – commonly known by the trade name KYNAR FLEX®) is a more flexible version of PVDF. Altaflo® 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 Altaflo® 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.
Altaflo® 550 is available in many standard sizes available to ship from stock. Custom sizes are available upon request.* Altaflo® 550 tubing is compatible with most standard fittings (not suitable for use with flare fittings).

The above information is based on tests performed at 73° F and can vary in individual applications based on parameters such as temperature, chemical concentration, pressure, etc. Please consult factory for details. For an estimate on burst pressure at ambient temperature we consider a 3:1 ratio when exposure temperature is 73° F. However Altaflo does not recommend exceeding the suggested Working Pressure listed.
