About These Items Hydraulic tube expanders are designed for a wide range of tube sizes. Models 78835 and 17350 cover sizes from 1-5/8" to 4-1/4", while the CT-300A is suitable for HVAC tube sizes from 3/8" to 1-1/8". These expanders can work with materials such as aluminum, copper, mild steel, and titanium, making them ideal for vehicle repair, HVAC systems, and more. Equipped with 10-ton hydraulic pumps, these expanders make tube expansion quick and easy, saving time and effort compared to traditional methods. Some models, like the 17350, feature a 6-foot high-pressure hose, while others include a 4-foot or 1.8-meter hose, allowing for comfortable reach during use. Each expander is constructed of aluminum alloy or stainless steel to ensure high strength and a long lifespan, even with frequent use. The components are rust-resistant, and rust-proof gears provide reliable performance. Additionally, some models feature a tubing cutter and deburring tools, removing sharp edges for a secure connection. The CT-300A and model 78835 include heavy-duty storage cases, ensuring the tools and heads stay organized and protected. These cases allow for compact storage and portability, making it easy to transport and store in tight spaces. These expanders are ideal for vehicles (exhaust pipe expansion), brake lines, fuel lines, HVAC systems, and more. They are also used in repair shops, HVAC industries, and general maintenance projects. Key Differences Model 78835 has an expansion range of 1-5/8" to 4-1/4" and is manual, suitable for expanding exhaust pipes and other tubing in vehicle systems. Model 17350 also covers the 1-5/8" to 4-1/4" range, but uses a pneumatic-hydraulic pump for greater power, making expansion easier in industrial applications. The CT-300A is more versatile, with seven expansion heads ranging from 3/8" to 1-1/8", and is designed specifically for HVAC systems, but can be used for other piping applications.
