Parker FTC-4 Compression Tube Union 1/4 in Pfa Ptfe

Product Description

The PARKER FTC-4 is a compression tube union designed to join two lengths of tubing with matching outside diameters in a single inline fitting. It accepts 1/4-inch OD tubing and relies on a plastic compression grip rather than ferrules or solder, making it suitable for clean, leak-resistant connections in fluid handling and instrumentation lines. The fitting body is constructed from PFA (Perfluoroalkoxy) with PTFE (Polytetrafluoroethylene) components, giving it strong resistance to aggressive chemicals, high-purity process fluids, and wide temperature swings. Plumbers, instrumentation technicians, and specialty fluid system installers typically handle this fitting in process piping, laboratory, or industrial service applications.

The FTC-4 is suited for applications where chemical compatibility, cleanliness, or corrosion resistance rules out metal fittings. Typical install scenarios include high-purity fluid lines, chemical dosing systems, laboratory tubing runs, and similar process environments where PFA or PTFE wetted surfaces are specified. The plastic compression grip design allows connection without special tooling, supporting efficient field assembly or bench fabrication of tubing assemblies.

Key Features

• Accepts 1/4-inch OD tubing on both ends for a straight inline union connection
• PFA and PTFE construction provides broad chemical resistance and high-purity compatibility
• Plastic compression grip style — no ferrule crimping or soldering required
• Lightweight at 0.1 pounds, suitable for space-constrained instrument panels or enclosures
• Single-piece union configuration simplifies tubing layout with no additional adapters

Compatibility

Designed as an OEM-style compression union for 1/4-inch OD tubing runs in chemical, laboratory, and high-purity fluid handling systems where PFA or PTFE wetted materials are required.

Installation Notes

Installation is typically performed by plumbers or instrumentation technicians familiar with plastic compression fittings. Shut off all fluid supply and depressurize the line fully before disassembly or fitting installation. Ensure tubing ends are cut cleanly and squarely to achieve a proper compression seal — do not use damaged or out-of-round tubing. Follow applicable plumbing or process piping codes and the fitting manufacturer guidelines for makeup torque and pressure testing after installation.
