S4R PFA Straight Union Reducers are designed to connect two fluoropolymer tubes with different outside diameters in laboratory, chemical and fluid-handling systems. Their PFA construction provides broad chemical resistance while the compact straight configuration enables clean transitions between selected tubing sizes in analytical, electrochemical and laboratory fluid-transfer assemblies.

Key Features

✓ PFA fluoropolymer construction
✓ Straight connection between different tube outside diameters
✓ Broad chemical resistance for demanding laboratory fluids
✓ Compact inline configuration
✓ Selected metric and fractional size combinations
✓ Designed for fluoropolymer laboratory tubing systems

Typical Applications

• Laboratory chemical and reagent transfer
• Electrolyte and solvent handling systems
• Electrochemical and battery research equipment
• Analytical and scientific instrumentation
• Transitions between different tubing diameters
• Corrosive fluid-handling assemblies

Chemical & Installation Compatibility
Verify tubing outside diameter, fitting size and chemical compatibility before installation. Metric and fractional tubing sizes are separate dimensional standards and should not be considered interchangeable. Operating pressure and temperature limits depend on the complete fitting and tubing system and are not specified here because these values have not yet been confirmed for this reducer series. For pressurized, vacuum-critical or safety-critical applications, verify the intended operating conditions before use.
