The YTKavq Brass Compression Fitting (10mm Tube OD) is a set of 50 pieces of brass compression sleeves/ferrules designed for use with tube fittings, primarily in plumbing, fluid, or pneumatic systems. Here's a detailed breakdown of the features and performance of this product:Pros:High-Quality Material: Made from brass, these compression fittings are durable and resistant to corrosion, making them suitable for use in various fluid or air systems. Brass is also a reliable material in both high and low-pressure environments, offering excellent longevity and stability.Wide Range of Applications: These fittings are designed for use with 10mm outer diameter tubes and are ideal for plumbing, air, fuel, or water systems. They are often used in a variety of DIY, home, automotive, and industrial applications.Precision and Fit: The compression sleeves are designed to tightly secure and seal around the tube, preventing leaks and providing a tight, reliable connection. The set includes 50 pieces, which is great for users who need to make multiple connections or are working on larger projects.Ease of Use: Compression fittings are known for their relatively simple installation process. They don’t require welding or soldering, which makes them user-friendly, even for beginners. The ferrules are easy to slip onto the tube, and the compression nut secures them firmly in place, providing a leak-proof seal.Cost-Effective: With 50 pieces in the set, this pack offers excellent value for those needing a large number of compression fittings. Whether you're doing a one-time project or have ongoing needs, the quantity ensures that you have enough to complete multiple fittings or replacements.Cons:Limited Tube Size Compatibility: These compression fittings are specifically designed for 10mm outer diameter tubes, so they might not be compatible with other sizes of tubing. If you're working with different tube dimensions, you’ll need to find other fitting sets tailored to those sizes.Not Ideal for High-Pressure Systems: While brass is strong and durable, these compression fittings might not be suitable for systems that require extremely high-pressure resistance. For more demanding applications, such as heavy-duty industrial systems, you may need fittings made from materials like stainless steel or higher-rated components.Can’t be Reused Often: Compression ferrules are typically meant to be used once. If the fitting is loosened or disassembled, the ferrule may not provide the same tight seal when reused, which can lead to leaks. This is something to keep in mind if you plan on reworking the system frequently.Overall:The YTKavq Brass Compression Fittings (10mm Tube OD) offer excellent value and reliability for a range of plumbing, fluid, and air system applications. Made of durable brass, these fittings ensure a tight, secure seal, preventing leaks in a wide variety of setups. The pack of 50 pieces is ideal for DIY projects, repairs, and installations, making it a great choice for those who need to work on multiple connections. However, these fittings are specifically for 10mm tubing, and while they are well-suited for most standard applications, they may not be ideal for very high-pressure systems or for repeated disassembly and reassembly. Overall, they provide a solid solution for anyone looking to create secure, leak-free connections in their systems.

I wanted to put some capricorn tubing on my printer and I needed 2 new olives to fix the tube between the extruder and the hot end. The process isn't that complicated but it was a little more intimidating than I had anticipated. Crimping these on to the ends was extremely easy, even for someone like me with no previous experience. I yanked on them when it was done and they're on there securely. I kinda hope I don't have to do it again too soon, but at least I have plenty to use when I do.

Very good
