Features & Benefits
Universal Chemical Resistance
PTFE withstands virtually all acids, bases, solvents, and oxidisers except molten alkali metals and elemental fluorine.
FDA Compliant Virgin PTFE
Pure virgin PTFE is FDA compliant for pharmaceutical, food-grade, and high-purity water process contact.
Convoluted Multi-Directional Movement
Convoluted profile provides axial, lateral, and angular flexibility in a compact face-to-face length.
Vacuum Rated SS316 Wire
Stainless steel wire helix prevents PTFE collapse under vacuum or negative pressure, maintaining full flow area.
No Metal Process Contact
All wetted surfaces are PTFE; steel flanges do not contact process fluid, eliminating corrosion and contamination risk.
