Key Benefits of ETFE Tubing
- Excellent chemical resistance
- Constructed with genuine Tefzel™ resin
- Holds pressure up to 4,000 psi (276 bar)
- 1/16” or 1/8” outside diameter available
- Maximum continuous operating temperature: 80 ºC
ETFE (ethylene-tetrafluoroethylene) tubing is an excellent fluoropolymer product that offers several benefits over tubing manufactured from PTFE, FEP, or PFA. These benefits include enhanced pressure holding capabilities, increased mechanical stability and lower gas permeability.
Application Note
ETFE tubing is an ideal choice for the fluid pathway between the vacuum degasser and the system’s pump. Its low gas permeability will help ensure the mobile phase solvents do not regas while in transit.
