Adjustable pex expander tool

Product Features：

Tool for expanding tubes in condensers, chillers, heat exchangers, finfan coolers, feedwater heaters and surface condensers.

Multi-Material Capable: Expertly expand copper, aluminum, brass, and mild steel tubes with consistent, high-quality results.

Micrometer-style Adjustment: Achieve exact expansion diameters with our fine-threaded, easy-to-use adjustment nut. Ensure perfect, consistent flares and beads across every joint for leak-free performance.

Secure Locking: The locking mechanism holds your setting firmly in place during operation, preventing slippage and guaranteeing repeatable accuracy.

High-Grade Materials: Forged from premium, heat-treated alloy steel for maximum strength and resistance to wear and fatigue.

Hardened Mandrels & Rollers: The critical expansion components are precision-ground and hardened to maintain a sharp, effective edge far longer than conventional models, reducing downtime and replacement costs.

Usage Instructions:

Prior to expanding a tube, the adjustable tube expander must be set up according to the required expansion length. This is done by adjusting the positioning nut to move the positioning sleeve to the correct location, then tightening the positioning screw. Retract the expander shell towards the small end of the mandrel. Next, insert the tube expander into the tube. Advance the mandrel to ensure tight contact between the mandrel, the expansion balls, and the tube's inner wall. Subsequently, use a ratchet wrench or tube expanding machine to rotate the mandrel clockwise. This causes the mandrel to advance automatically while the expansion balls rotate in the opposite direction, rolling against and compressing the tube wall. This action forces the metal to expand, increasing the tube diameter until the expansion requirements are met. For withdrawal, simply rotate the mandrel counterclockwise. The mandrel will retract automatically, allowing the expander to be loosened and removed from the tube.

Please let us know the inner diameter of the pipe and the length of the adjustment, we will customize according to your requirements.
