Featuring a 20% larger hydraulic oil chamber for enhanced expansion power, durable 45# steel and aluminum alloy construction, and a flexible quick-release valve, this kit includes 7 expander heads, a tube cutter, and a deburring tool all housed in a rugged carrying case. Ideal for HVAC, underfloor heating, and plumbing applications, it streamlines installation while reducing costs and leakage risks. ## Description DetailsPractical Tube Cutter: This portable and compact tube cutter cuts pipes evenly and flatly by rotating the cutting wheel precisely.Ergonomic Handle: The ergonomic, curved handle on the tube expander is made of soft rubber for a comfortable grip. The handle has an automatic rebound function, which makes it easier and more energy-saving to use.How to Use1. Remove burrs from the inside of the tube.2. Anneal the tube if necessary (for hard or thick wall tubes).3. Screw the expander head onto the expander.4. Insert the end of the tube fully into the expander.5. Tighten the relief valve knob to the ‘ON’ position, then pump handle until the tube is expanded to the end.6. Turn the pressure-reducing valve to the OFF position to release the expander head and remove the expanded tube.SpecificationModel: CT-300Material: 45# Steel and Aluminum AlloyColor: Silver, BlackPower Source: Manual Hydraulic-poweredCarrying Case Color: BlueExpander Heads Size: 3/8'', 1/2'', 5/8'', 3/4'', 7/8'', 1'', 1-1/8''Hydraulic Tube Expander Size: 28*12cm/11*4.7inCut Tube Size Range: 6-50 mm/0.25-2inTube Cutter Length: 18cm/7.1inDeburring Tool Length: 15cm/5.9inPacking Size: 45*25*7cm/17.71*9.84*2.75inGross Weight: 3kg/6.61lbsPackage Included1 * Hydraulic Tube Expander1 * Tube Cutter1 * Deburring Tool7 * Expander Heads1 * Blue Carrying Case1* English User ManualNotes1.For hard tubes, please anneal the tube before expanding to prevent cracking or hard expanding.2.Please allow the slight color difference caused by the shooting light and 1-3 cm error due to manual measurement, and make sure you do not mind before ordering. ## Features - ✔【High-quality Materials】It is made of high-quality 45# steel and aluminum alloy, which is hard, durable, scratch-resistant, and wear-resistant, ensuring a long service life. - ✔【High Efficiency】The hydraulic oil chamber of the hydraulic expander is 20% larger than the normal one. This allows for greater expansion when using the same force, without having to worry about the R410 thickened pipes. Compared to traditional welding, this hydraulic tube expander requires only one side to be welded, reducing installation costs and the possibility of leakage. - ✔【Manual Hydraulic Design】With its manual hydraulic mechanism design, it is easy to grasp the degree of expansion and prevent pipe cracking, making it easy and efficient to complete expansion work. - ✔【Flexible Valve】With a flexible hydraulic control valve on the expander, you can quickly release the pressure and remove the tube when expansion is complete, greatly increasing your efficiency. - ✔【Application】With 7 expander head sizes, it can be used to expand a wide range of tubes from 3/8" to 1-1/8" to meet your different needs. It is mainly used in underfloor heating, air conditioning, sanitary ware and other areas to expand copper or aluminum tubes. - ✔【Complete Kit】This is a complete hydraulic expansion kit with all the tools you need for expanding the pipe, so you don't need to buy them separately, which is very convenient and hassle-free. It's lightweight (6.61lbs) and all the tools are stored in a plastic carrying case, making it very easy to carry around. - ✔【Stable and Secure Placement】The carrying case has specially designed slots to accommodate tools of different shapes and sizes, making them more securely placed, while reducing damage to the tools when transporting or carrying them. ## Images ![Hydraulic Tube Expander, CT-300 HVAC 3/8"-1-1/8" 7 Lever Hydraulic Swaging Tool Kit with Tube Cutter for Copper Tubing Expanding Copper Tube Expander - Image 1](https://m.media-amazon.com/images/I/61Ws8RL5JhL.jpg) ![Hydraulic Tube Expander, CT-300 HVAC 3/8"-1-1/8" 7 Lever Hydraulic Swaging Tool Kit with Tube Cutter for Copper Tubing Expanding Copper Tube Expander - Image 2](https://m.media-amazon.com/images/I/71hQb62UpDL.jpg) ![Hydraulic Tube Expander, CT-300 HVAC 3/8"-1-1/8" 7 Lever Hydraulic Swaging Tool Kit with Tube Cutter for Copper Tubing Expanding Copper Tube Expander - Image 3](https://m.media-amazon.com/images/I/71lKC8WBP2L.jpg) ![Hydraulic Tube Expander, CT-300 HVAC 3/8"-1-1/8" 7 Lever Hydraulic Swaging Tool Kit with Tube Cutter for Copper Tubing Expanding Copper Tube Expander - Image 4](https://m.media-amazon.com/images/I/71hBjPTjJDL.jpg) ![Hydraulic Tube Expander, CT-300 HVAC 3/8"-1-1/8" 7 Lever Hydraulic Swaging Tool Kit with Tube Cutter for Copper Tubing Expanding Copper Tube Expander - Image 5](https://m.media-amazon.com/images/I/71RqNumvKmL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/808655473-hydraulic-tube-expander-ct-300-hvac-3-8-1-1](https://www.desertcart.hr/products/808655473-hydraulic-tube-expander-ct-300-hvac-3-8-1-1) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-06*
