Pexco / Altaflo
UHP PFA, dual-containment tube-in-tube tubing, and PVDF — built for semiconductor, pharmaceutical, and other high-purity chemical delivery where a leak has to be both contained and visible.
Pexco is the manufacturer behind Altaflo fluoropolymer tubing. The 480 line uses 100% virgin Daikin AP-231SH UHP PFA, resistant to fluorosurfactants, with a tube-in-tube dual containment version whose clear FEP outer tube makes inner-tube leaks visible. The range also includes PTFE, FEP, THV, and PVDF tubing for semiconductor, pharmaceutical, and high-purity delivery.
What LibertyCES specifies from Pexco / Altaflo
Inner tube: 100% virgin Daikin AP-231SH UHP PFA, SEMI F-57 and C-90 approved. Outer tube: clear FEP so a leak in the inner tube is visually detectable without disassembly. Named for semiconductor and pharmaceutical critical chemical delivery.

Made exclusively from high molecular weight, high-purity resin. Resistant even to fluorosurfactants known to attack lower PFA grades, lowest permeation and smoothest surface finish in the line. Named applications: semiconductor, chemical process, gas analyzing, emissions monitoring, pharmaceutical.
200 FEP: 400°F service, outstanding clarity and UV transmission for sight-glass and UV-purification service. 350 THV: a distinct fluoropolymer chemistry chosen for UV transmission combined with flexibility.
500: 100% virgin Kynar 740 homopolymer, NSF 61 and NSF 372 certified, extremely low extractables — called out for ultrapure water systems. 550 Flex: Kynar Flex, explicitly ozone-resistant, named for semiconductor and water purification.

Frequently Asked Questions
Who actually manufactures Altaflo tubing?
Pexco is the manufacturer behind the Altaflo® fluoropolymer tubing brand. Distributors like Harrington Industrial Plastics sell Altaflo product, but Pexco is the source manufacturer.
What makes Altaflo 480 Dual Containment tubing different from a standard double-contained line?
It is a purpose-built tube-in-tube design, not a pipe retrofitted with an outer sleeve: a 100% virgin Daikin AP-231SH UHP PFA inner tube (SEMI F-57 and C-90 approved) inside a clear FEP outer tube, so a leak in the inner tube is visually detectable through the outer tube without disassembly.
Is Altaflo UHP PFA resistant to fluorosurfactants?
Yes — the 480 UHP PFA grade is explicitly rated resistant to fluorosurfactants, a chemical class the vendor specifically calls out as capable of attacking lower PFA grades. Not every PFA grade offers the same resistance.
