Parker GEC-6 Compression Tube Union 3/8 in Pfa Ptfe

Product Description

The PARKER GEC-6 is a compression tube union designed to join two lengths of tubing in a straight-line connection without the use of solder, adhesives, or threaded fittings. Built from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE) materials, this fitting is suited for high-purity, chemically aggressive fluid handling systems. It accepts 3/8-inch outside diameter tubing and uses a plastic grip-type compression mechanism that creates a secure, leak-resistant seal. Plumbers, process piping technicians, and chemical handling professionals typically install this fitting in systems where corrosion resistance and purity are critical requirements.

This union fitting is commonly used in laboratory fluid distribution, semiconductor fabrication, chemical processing lines, and other industrial or commercial applications requiring inert, non-contaminating connections. Its PFA and PTFE construction makes it well-suited for use with aggressive chemicals, high-purity water systems, and environments where metallic fittings would be subject to corrosion or contamination. The compression design allows for tool-minimal installation and straightforward field assembly.

Key Features

• 3/8-inch tube OD compatibility for standard tubing sizes used in process and chemical systems
• PFA and PTFE construction provides excellent chemical resistance and low extractables
• Plastic grip-type compression mechanism eliminates the need for solder or adhesives
• Straight union configuration allows in-line tube-to-tube connections
• Compact, lightweight design at 0.1 pounds for easy handling and installation in tight spaces

Compatibility

Designed as an OEM-style compression union for use with 3/8-inch OD flexible or rigid tubing in chemical, laboratory, and high-purity fluid handling systems.

Installation Notes

Installation is typically performed by qualified plumbers or process piping technicians familiar with compression-style plastic fittings. Shut off and depressurize the fluid system fully before disassembly or fitting installation. Ensure tubing is cut cleanly and squarely to achieve a proper compression seal. Follow applicable IPC or facility-specific codes governing chemical and high-purity fluid systems when selecting and installing fittings.
