Maus MG-800 Series Tube Expanders
Premium 3-Roller Expansion for Thin Tubesheets
Reliable Sealing Performance
The Maus MG-800 Series represents high-quality mechanical expansion technology designed for efficiency in thin tubesheet environments. By utilizing a 3-roller balanced configuration, these tools apply uniform radial pressure, which is critical for creating a leak-free mechanical bond between the tube and the tubesheet.
Key Advantages
- • Adjustable Depth: Versatile collar settings for varying tubesheet thicknesses.
- • Durability: Tempered, case-hardened alloy steel construction.
- • System Integration: Optimized for use with torque-controlled pneumatic/electric drivers.
