Produkbeskrywing
High-Grade Material Construction: Each expander is forged from heat-treated 40Cr steel with black oxide coating, providing exceptional strength and corrosion resistance. The powder metallurgy sleeves ensure smooth operation and extended tool life under heavy use.
Precision Size Gradation: The set includes three professionally calibrated expanders – small (1-1/8″-1-3/4″), medium (1-1/2″-2-1/2″), and large (2-1/8″-3-1/2″) – covering all common exhaust pipe dimensions. Each unit features progressively sized hex drives (16mm to 19mm) for proper torque transfer.
Engineered for Professional Use: The tapered mandrel design allows controlled, gradual pipe expansion without creating stress fractures. Hex drive compatibility enables use with impact wrenches for efficient shop workflow.
Durability Features: Heat-treated components withstand repeated use on stainless steel and aluminized pipes. The black oxide finish reduces friction while preventing rust in automotive workshop environments.
