Parker MFT-04 Parflare Tube Flare Mandrel 1/4 Inch Od

Product Description

The PARKER MFT-04 is a Parflare tube flare mandrel designed to create precision flared ends on 1/4-inch OD tubing for compression-style tube connections. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE) materials, this mandrel delivers chemical resistance and dimensional stability required in demanding fluid and gas handling applications. Weighing 0.22 pounds, the MFT-04 is a compact, single-use-per-operation hand tool used by plumbers, HVAC technicians, and industrial piping professionals who work with fluoropolymer tubing systems where leak-free flared connections are required.

The MFT-04 is suited for use with 1/4-inch OD fluoropolymer tubing in systems that require Parflare-style compression fittings. Typical applications include chemical process lines, high-purity fluid transfer systems, and instrumentation tubing where PFA or PTFE tubing is specified for its resistance to aggressive media. This mandrel prepares the tube end to the correct flare geometry before the compression fitting is seated, ensuring a proper seal without adhesives or thread sealants.

Key Features

• Accepts 1/4-inch OD tubing for Parflare-style flare preparation
• PFA and PTFE construction provides excellent chemical and thermal resistance
• Produces consistent flare geometry for reliable compression-seal connections
• Lightweight at 0.22 pounds for easy field and bench use
• Single-piece mandrel design with no moving parts to maintain or replace

Compatibility

Designed for use with PARKER Parflare compression fitting systems on 1/4-inch OD PFA and PTFE fluoropolymer tubing. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation is typically performed by licensed plumbers or qualified industrial piping technicians familiar with fluoropolymer tube systems. Before flaring, ensure the tube end is cut square and deburred to prevent an uneven flare. Apply only hand pressure as specified by the fitting manufacturer when seating the mandrel — do not use power tools or excessive force, which can crack or distort the tube end. Follow applicable codes and the fitting manufacturer's assembly instructions for final torque and connection verification.
