Natural PTFE tube
The original fluoropolymer, extruded to tight tolerances.
PTFE tube
Virgin, unfilled PTFE. Near-universal chemical resistance, −200 to +260 °C, smooth non-stick bore.
Natural PTFE tube is virgin polytetrafluoroethylene paste-extruded into a flexible, semi-transparent white tube. It is unfilled and unpigmented, so it keeps the full PTFE property set: near-universal chemical resistance, a −200 °C to +260 °C working range and a smooth, non-stick bore.
We make it by ram and paste extrusion for consistent dimensions and minimal wall eccentricity, with every length traceable under ISO 9001:2015.
