Tube Flaring Expanders 9.5mm to 11mm (3/8" - 7/16")

These tube flaring expanders are specifically designed for creating precision flares on condenser, heat exchanger, and similar tubing. Ideal for shipboard maintenance and repair, they ensure a secure, leak-tight seal when installing tubes in tube sheets. The tool is crafted from selected, hardened tool steel for exceptional durability and long service life, even in demanding marine environments.

With a size range of 9.5mm to 11mm (3/8" to 7/16") inner diameter, these expanders accommodate common tube sizes found in marine cooling systems. The 8mm square drive allows for easy use with standard ratchets or handles. For best results, select the largest expander that fits the tube's inner diameter to achieve optimal flaring.
