Parker FSC-6 Compression Tube Union 3/8 in Pfa

Product Description

The PARKER FSC-6 is a compression tube union designed to join two lengths of tubing at equal outside diameters without the need for soldering, flaring, or threaded fittings. This fitting accepts 3/8 inch OD tubing and uses a plastic grip mechanism to create a secure, leak-resistant compression seal. The body is constructed from PFA (perfluoroalkoxy alkane), a fully fluorinated thermoplastic that offers broad chemical compatibility and high-purity fluid handling characteristics. It is commonly installed by plumbers, process technicians, and mechanical contractors working on fluid transfer, instrumentation, or chemical handling lines.

This union fitting is suited for tubing runs in laboratory, industrial process, semiconductor, and high-purity fluid applications where chemical resistance and low contamination risk are priorities. The compression-style connection allows for field assembly without specialized tooling, making it a practical choice for both new installations and service replacements in tight or sensitive environments. Refer to system design requirements to confirm temperature and pressure ratings for the specific application.

Key Features

• 3/8 inch tube OD compression fitting for equal-diameter union connections
• PFA body material provides excellent chemical resistance and high-purity fluid compatibility
• Plastic grip compression mechanism allows tool-free or minimal-tool field assembly
• Straight union configuration simplifies inline tube-to-tube connections
• Compact, lightweight design at 0.1 pounds

Compatibility

Designed as an OEM-style compression union for 3/8 inch OD tubing in laboratory, instrumentation, and industrial process fluid systems requiring PFA wetted components.

Installation Notes

Installation is performed by qualified plumbers or process piping technicians familiar with compression-style fluoropolymer fittings. Shut off and depressurize the fluid line completely before disassembly or installation. Ensure tubing ends are cut square and free of burrs before seating into the compression fitting to achieve a proper seal. Follow applicable system pressure and temperature ratings as well as any relevant piping codes for the installation environment.
