Specialized 4.75MM brake tube, including handle, positioning bolt, punch and lubrication container. It can precisely expand the bubble opening and double expansion openings, ensuring a tight seal without any leakage. The strong and durable mold is easy to store in a portable box without losing any parts. It is suitable for auto repair, DIY oil change tubes, and can achieve professional expansion results with manual operation.

It is specifically designed with a 4.75MM brake pipe, and the 3/16-inch flange specification is precisely suitable for common pipelines. It comes with a detachable handle + positioning bolt + single-head punch. Without the need to find additional tools, a complete set can handle the flange expansion: Insert the pipe into the mold, and by turning the bolt, you can precisely expand to form a "bubble opening / double flange", without any distortion or cracking. The connected pipeline fits tightly without any leakage.When repairing the brake hose, if the hose interface doesn't align properly or the flange is misshapen and leaks fluid? This brake hose flange expander packs "professional flanging" into a portable case, making it easy for auto mechanics and DIY enthusiasts to use.

The connected hose will fit tightly without any leakage.
Durability is the "solid backing": The mold is made of strong materials, so it won't deform during flanging and can maintain accuracy even after repeated use. It is also equipped with a dedicated lubrication container, which makes the flanging smoother after applying oil to the mold, protecting the tools and making the hose opening more regular.
The portable case design is very thoughtful: Tools have dedicated slots, so after use, they won't be lost. Put it in your tool bag and you can take it out and use it - whether it's repairing brake hoses at an auto repair shop or replacing the oil pipe for your car yourself, you can take it out and use it without having to search in the toolbox.
Whether it's dealing with the connection of brake hoses or repairing hydraulic pipelines, it can turn "flanging" from a "technical task" into an "easy task": Without relying on large equipment, you can achieve professional results through manual operation, saving time for equipment search and avoiding rework due to substandard flanging.
Now, have it on hand, and next time you need to repair brake hoses, you won't be panicked: Insert the hose, tighten the bolt, and expand the flange. Three steps and the connected hose will be sealed tightly and fit precisely, making the braking system more reliable.
