Glass thread adapters enable secure connection of laboratory glassware with GL threads to hose and pipe systems. These specialized connecting elements bridge the design differences between glass threads and standard connection technology in chemical process engineering.

Material diversity for different requirements

The adapters are manufactured from various high-performance plastics. Polypropylene (PP) offers mechanical strength and chemical resistance at temperatures from +5°C to +90°C. Polyvinylidene fluoride (PVDF) is characterized by highest purity requirements and temperature resistance up to +140°C. Perfluoroalkoxy (PFA) ensures virtually universal chemical resistance from -200°C to +200°C. Polybutylene terephthalate (PBT) offers exceptional wear resistance and dimensional stability up to +180°C.

Versatile connection options

The adapter systems cover all common GL thread sizes from GL 12 to GL 45. Depending on the design, they enable connection of elastomer hoses, rigid plastic pipes or standard G threads. Pressure loads up to 6 bar for hose and thread adapters as well as up to 1 bar for pipe connectors are achievable.

Product overview
