Automotive exhaust pipe expansion tool, suitable for pipe diameters of 29-89mm. Three sets of expansion heads cover all common specifications. Made of alloy steel, it is sturdy and wear-resistant. The manual mechanical expansion mechanism applies force evenly, and the expansion opening is smooth without damaging the pipe wall. The complete set comes with a pressure-resistant storage box, which is portable and easy to store.

The entire set of tools includes three different-sized expansion heads, which cover all common sizes from small to large diameters in a graded manner. They can gradually stretch the pipe wall and expand the inner diameter of the pipeline as needed, making them highly suitable for repairing compressed and deformed exhaust pipes, connecting two sections of pipes with matching diameters, and modifying the exhaust tail section. They effectively solve various problems such as inability to connect due to inconsistent pipe diameters at the junction and concave or collapsed pipe openings.This set of professional exhaust pipe expansion tools is specially designed for the maintenance and modification of car exhaust pipes. The applicable pipe diameter range is from 29mm to 89mm. Most of the iron exhaust pipes of domestic cars, SUVs, and vans can be compatible with it. It is a necessary special tool for auto repair stores and daily maintenance of vehicle modifications. It can easily complete the operations of expanding the exhaust pipe holes, expanding the pipe, and repairing the pipe connection.
The expansion structure is mechanical and manual. It is driven by the rotation of the screw to evenly expand the expansion tiles. The force is distributed evenly, and the pipe opening expands smoothly and roundly without any single-sided skewing, wrinkling, or cracking. It can be completed by a single person holding the tool without the need for hydraulic equipment assistance. It can be operated flexibly in a narrow chassis space, making it convenient and worry-free for on-site maintenance and lifting machine repair positions. The tool is equipped with a matching elastic sealing ring accessory, which is convenient for disassembly, maintenance, and prolonging the service life of the entire set of tools.
The storage configuration includes a thick hard plastic toolbox. The box body is pressure-resistant and shock-proof. The internal precise slots fix each component, preventing shaking and collision. The accessories are neatly arranged in categories, making it convenient to take and find. The box body is equipped with a handhold handle, making it easy to carry and transport when going out. It can also be stored and not occupy the warehouse space when not in use.
Whether it is repairing exhaust pipe dents and depressions, connecting new and old exhaust pipe parts, or modifying the exhaust system, it can complete the operation efficiently, replacing the rough method of grinding and cutting. The construction efficiency is higher, the pipe opening formation effect is better, the workmanship is sturdy and durable, and it is stable after repeated use in long-term auto repair operations. It significantly reduces the difficulty of exhaust repair construction.
