Introducing the MalcoEdge TEH375 Tubing Expander Head — a precise, professional-grade tool designed for 3/8-inch copper and aluminum tubing in HVAC and refrigeration systems.

Designed to deliver consistent expansions, the TEH375 creates a tight, reliable end that eliminates the need for couplings in many line connections. By expanding the tubing end directly, it allows for cleaner assemblies with fewer leak paths and faster service calls on-site.

Constructed from hardened steel, the TEH375 is built to endure the wear of field work. Its rugged construction resists rounding or deformation during repeated use, ensuring steady performance from the first turn to the last.

Seamless integration with the MalcoEdge TEMS expander tool means technicians can add this head to their workflow without extra setup. The alignment and fit are engineered for accurate, repeatable results, giving you confidence on every installation or service task.

• Expansion size: optimized for 3/8-inch copper and aluminum tubing common in HVAC/refrigeration lines.
• Coupling-free joints: produces tight expansions that reduce the need for adapters, saving time and reducing potential leak points.
• Durable construction: hardened steel stands up to daily field use.
• Tool compatibility: designed to pair with MalcoEdge TEMS expander tool for precise, field-ready performance.
• Application versatility: ideal for service calls, new installations, and retrofit work involving 3/8" copper or aluminum lines.

Practical use tips: ensure tubing ends are clean and burr-free for the best fit, and verify correct alignment before expanding to avoid misfits. When you need a reliable, repeatable expansion in HVAC or refrigeration projects, the MalcoEdge TEH375 Tubing Expander Head is the dedicated choice for 3/8" copper and aluminum tubing.
