DURAN Wheaton Septa (224168) PTFE Face Gray Butyl

DURAN Wheaton Septa (224168) PTFE Face Gray Butyl

The DURAN Wheaton Septa (224168) PTFE Face Gray Butyl septum designed for unlined aluminum seals with a 20 mm outer diameter. It ensures a tight, chemically inert, and long-lasting seal, ideal for analytical, pharmaceutical, and chemical laboratory environments.

The DURAN Wheaton Septa combines a PTFE (polytetrafluoroethylene) face for superior chemical resistance with a gray butyl backing that provides low gas permeability and excellent mechanical strength. This dual-layer design delivers optimal performance in applications requiring sample integrity, solvent resistance, and airtight closure.

The gray butyl layer maintains elasticity and low extractable content, making it ideal for use in chromatography, reagent storage, and quality-control testing. The PTFE surface prevents sample interaction, ensuring purity and accuracy during analysis or long-term containment.
