Green Thermoset Plastic Caps with F217 and PTFE liners are known for providing the widest range of chemical compatibility.

• The color green easily identifies the F217 & PTFE liner system
• F217 foam-backed PTFE liners resist attack from virtually all chemicals at room temperature
• Provides odor and impact resilience for a tight seal with a low moisture transmission rate

The F217 features a low-density foam core between two LDPE discs. They are applied to the back of a PTFE liner.

Some uses for these F217/PTFE lined caps include analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents.
