Meet the MalcoEdge TEH250 Tubing Expander Head—a precision-machined 1/4-inch expansion head built for small-diameter copper and aluminum tubing in HVAC and refrigeration service. This dedicated expander head delivers clean, uniform expansions that minimize the need for fittings and brazing, speeding up installations and reducing potential leak points in tight spaces.

Designed to pair seamlessly with the MalcoEdge TEMS expander tool, the TEH250 locks into place for consistent, dependable connections. In compact installations—think service panels, evaporator and condenser lines, or tight cabinet spaces—you’ll enjoy tight, leak-resistant joints that stand up to daily service demands.

Key benefits that set TEH250 apart

• Precise 1/4-inch expansion: Specifically engineered for small-diameter copper and aluminum tubing, ensuring accurate, repeatable results.
• Leak-resistant connections: Uniform expansions reduce gaps and misalignment, lowering the risk of leaks in critical HVAC/refrigeration lines.
• Fewer fittings and brazing: Clean expansions mean fewer joints to braze or adapt, saving time on installation and service.
• Compact, durable design: Built to endure on-the-job use in tight spaces, with reliable performance whenever space is at a premium.
• Seamless TEMS integration: Optimized compatibility with the MalcoEdge TEMS expander tool for streamlined workflows.

Ideal use cases

• Servicing small-diameter copper or aluminum tubing in HVAC systems and refrigeration units.
• Creating clean, ready-to-join ends in tight installation environments where brazing is impractical.
• Repairs or retrofits in confined compartments, cabinets, or ceiling zones where accessibility is limited.

Practical tips for best results

• Prepare tubing by removing burrs and deburring edges to ensure smooth insertion and optimal expansion.
• Use the TEH250 in conjunction with the TEMS expander tool for aligned, consistent results every time.
• Inspect expanded ends for uniformity; repeatable, even expansions contribute to reliable, leak-free performance.
