Teflon Ring(White Color)

A Teflon Ring (White Color) is a circular sealing or support component made from PTFE (Polytetrafluoroethylene) — commonly known by the brand name Teflon. These rings are chemically inert, thermally stable, and mechanically durable, making them ideal for high-performance applications in laboratory, industrial, and chemical environments. The white color is characteristic of pure virgin PTFE, signifying a high level of purity and non-contamination — critical in applications where chemical resistance and non-reactivity are essential.

Teflon rings may be used as:

• Sealing gaskets in glassware joints or flanges

• Spacer rings in reactor vessels or filter assemblies

• Insulating components in electrical or thermal setups

They offer exceptional resistance to corrosive chemicals, solvents, acids, bases, and extreme temperatures (from -200°C to +260°C). Unlike rubber or silicone, PTFE does not degrade or leach contaminants, making it ideal for cleanroom, pharmaceutical, and analytical chemistry applications.
