Designed for both shop and home use, the set supports pipes with wall thicknesses up to 0.06 inch and is intended to pair with common impact tools for faster operation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the VEVOR expander handle different pipe sizes?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit includes seven interchangeable collets that cover a wide diameter range, allowing one tool to work across multiple pipe sizes without modifications. Each collet engages the inner surface evenly to produce a uniform expansion that aids alignment and fit-up during assembly.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSeven collets span from 1-5\/8\" to 4-1\/4\" diameters.\u003c\/li\u003e\n  \u003cli\u003eWorks on low-carbon steel and stainless steel pipes with up to 0.06\" wall thickness.\u003c\/li\u003e\n  \u003cli\u003eCollets are replaceable for long-term use and varied applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction ensure durability?\u003c\/h3\u003e\n\n\u003cp\u003eCritical load parts are made from hardened carbon steel to resist deformation under torque, while the body uses lightweight aluminum to keep the tool manageable during repeated operations.

Clamp the collet into the pipe, attach the expander, and apply steady torque—using a 1\/2\" or 3\/4\" impact wrench speeds the process but manual drivers can also be used for finer control.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eLubricate all moving parts before use to reduce wear and ease expansion.\u003c\/li\u003e\n  \u003cli\u003eChoose the closest-fitting collet and secure it in the pipe before expanding.\u003c\/li\u003e\n  \u003cli\u003eUse recommended impact wrench sizes for faster, consistent results.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes with the kit and how is it stored?\u003c\/h3\u003e\n\n\u003cp\u003eThe set is packaged in a rugged carrying case that protects components and keeps each collet and accessory organized for transport and on-site jobs.
