DAYUAN 3 Piece 1-1/8 Inch to 3-1/2 Universal Exhaust Pipe Expander Set for Diameter 29 89 mm, Pipes

Precise expansion: the exhaust pipe expander set extends pre-stretched or muffled pipe ends evenly and prevents conical deformation. Ideal for straightening, widening and adjusting exhaust pipes for precise connections. Robust forged steel: the pipe expanders are made of high-quality hot-forged steel and offer high strength, wear resistance and long service life. Suitable for demanding repair and assembly work on exhaust systems. Correct use: insert at least three quarters of the exhaust expander into the pipe and turn the hex drive clockwise. Do not use with an impact wrench and do not overload the tool. Only suitable for re-shaping and expanding already muffled pipe ends, not for the first time expanding straight pipes. THREE SIZES: Small pipe expander: 1-1/8 to 1-3/4 inch; Medium pipe expander: 1-1/2 to 2-1/2 inch; Large pipe expander: 2-1/8 to 3-1/2 inch. Helps eliminate dents, pressure points and bumps and allows for firm, precisely fitting pipe connections. Complete exhaust tool set: contains three exhaust pipe expanders in different sizes as well as matching O-rings for each size. Suitable for repair and installation of exhaust systems on many cars and trucks. The sturdy red storage box allows for clear storage and easy transport.
