RCT Reichelt Chemietechnik

Ground joint seals and bellows made of polytetrafluoroethylene (PTFE) ensure reliable sealing in demanding laboratory applications. These precision components enable gas- and liquid-tight standard ground joint connections for vacuum applications up to 0.1 mbar and temperatures up to 300°C.

High-Vacuum Ground Joint Seals for Critical Applications

PTFE ground joint seals offer exceptional chemical resistance and thermal stability. The reusable flat sealing rings ensure permanent sealing between glass ground joint connections. Flanged cone ground joint seals cover standard ground joint sizes from NS 10/19 to NS 100/60 and are suitable for high-vacuum connections in gas and liquid lines.

Flexible Bellows as Compensation Elements

Standard ground joint bellows made of PTFE function as highly flexible compensation elements between structural components. The special fold geometry compensates for pressure loads and thermal expansion. With vacuum-tight construction and standard ground joint ends (socket/core), these components are optimally suited for valve technology and industrial applications up to 200°C.

FDA-Compliant Solutions for Regulated Areas

The sterilizable PTFE components meet FDA requirements and are suitable for food and pharmaceutical industries. Extension elements enable individual adaptations of standard lengths.
