The MalcoEdge TEH750 Tubing Expander Head redefines reliability in HVAC and refrigeration installations by delivering a precise 3/4-inch expansion for copper and aluminum tubing. Built for demanding environments, this rugged tool creates clean, repeatable expansions that eliminate the need for couplings and solder joints, helping you achieve leak-resistant joints right from the first fit.

Designed with professional-grade materials and tight tolerances, the TEH750 sustains high-flow performance without compromising accuracy. Its robust construction stands up to daily use on the shop floor or in the field, ensuring consistent results across multiple jobs and technicians.

Why the TEH750 stands out

• Precise 3/4-inch expansion head tailored for larger HVAC tubing applications
• Works with copper and aluminum tubing, expanding cleanly without collapsing or cracking
• Creates tight, uniform expansions that negate the need for couplings and solder joints
• Leak-resistant joints that improve system integrity and reduce service calls
• Rugged, high-precision design built for professional use
• Seamless compatibility with the MalcoEdge TEMS expander kit for streamlined workflows

Ideal for who and when

This head is a must-have for HVAC technicians, commercial refrigeration installers, and service teams tackling high-flow systems where maximum throughput and leak-free performance matter. It shines in retrofit projects, system upgrades, and new installations where large-diameter tubing is required and soldering is impractical or time-prohibitive.

Concrete benefits you’ll notice

• Faster installations thanks to single-piece, solderless expansions
• Reduced leak risks with a consistently formed expansion every time
• Less thermal distortion and fewer heat-affected joints during on-site work
• Long-term reliability for high-demand systems due to robust construction

Practical tips for best results

Pair the TEH750 with the MalcoEdge TEMS expander kit to maximize compatibility and efficiency. Ensure tubing ends are clean and burr-free before expansion to maintain a smooth, uniform profile. Use steady, controlled pressure to achieve the 3/4-inch expansion without over-stressing the tube wall, and inspect each joint for uniformity after expansion to confirm a leak-free seal.
