Applications

PTFE and PFA tubing carries aggressive media in chemical plant, analytical equipment and dosing systems.

The smooth bore resists deposits and can be flushed clean; PFA is chosen where a transparent, weldable tube is needed. Assembly is by compression ring fittings or support sleeves.
