Craftsman Fluid Extractor

Extracting fluids from automotive systems can often be a cumbersome task, especially when dealing with reservoirs that are hard to reach. The Craftsman Fluid Extractor, model CMMT98350, promises to simplify this process with its user-friendly design and practical features. Over the course of several uses, I’ve had the opportunity to put this extractor to the test, assessing its performance, build quality, and overall utility.

Design and Build Quality

The Craftsman Fluid Extractor is constructed from polypropylene, a material known for its chemical resistance. This is a critical feature, as it ensures that the extractor can handle a variety of automotive fluids without degrading over time. The tool feels robust in hand, and its lightweight nature (weighing just 0.7 pounds) makes it easy to maneuver during use.

One of the standout features of this tool is its see-through barrel. This design choice allows you to monitor the fluid extraction process in real-time, ensuring you can see how much fluid has been removed. The barrel holds up to 7 ounces of fluid, which is sufficient for many small to medium-sized tasks. However, for larger jobs, you may find yourself needing to empty the barrel multiple times.

Performance and Usability

Using the Craftsman Fluid Extractor is straightforward. It includes hose extensions over 15 inches in length, making it easier to reach into tight spaces. This was particularly useful when I was extracting oil from my riding mower’s reservoir. The double plunger seals are designed to reduce leaking, and I found them to be effective in maintaining a good suction seal during use.

The tool performed admirably in several fluid extraction tasks. Whether it was removing excess oil from an overfilled reservoir or changing the oil in small engines without tipping them over, the extractor made the process significantly cleaner and more efficient. The suction power was adequate for most tasks, and the see-through barrel helped me gauge the fluid levels accurately.

Pros and Cons

Pros:

1. Chemical Resistance: The polypropylene construction ensures longevity and resistance to various automotive fluids.
2. Visibility: The see-through barrel allows for easy monitoring of fluid levels.
3. Ease of Use: The lightweight design and long hose extensions make it easy to handle and reach difficult spots.
4. No Mess: The double plunger seals effectively reduce leaking, minimizing the mess usually associated with fluid extraction.

Cons:

1. Capacity: With only a 7-ounce capacity, the barrel may require frequent emptying for larger tasks.
2. Plunger Issues: Some users might experience problems with the plunger not holding suction effectively, leading to fluid draining back down the hose.

Real-World Applications

I used the Craftsman Fluid Extractor in various scenarios, from routine oil changes to more specific tasks like bleeding brakes on small machinery. In each case, the tool performed well, fulfilling its intended purpose without significant issues. One particular instance was the replacement of a radiator, where the extractor was invaluable in removing old fluid from the reservoir. The process was clean and efficient, saving me time and preventing spills.

While the tool is generally reliable, there were a few instances where the suction didn’t hold as well as I would have liked. This was particularly noticeable when dealing with thicker fluids. However, these instances were relatively rare and didn’t significantly impact the overall usability of the tool.

Craftsmanship and Durability

The Craftsman brand is synonymous with quality, and this fluid extractor lives up to that reputation for the most part. The materials used are durable, and the construction feels solid. However, there were occasional issues with the plunger not sealing perfectly, which could lead to minor leaks. This was more of an annoyance than a major flaw, but it’s something to be aware of if you’re planning to use the tool frequently.

Final Thoughts

The Craftsman Fluid Extractor (CMMT98350) is a valuable addition to any DIY mechanic’s toolbox. Its combination of chemical resistance, ease of use, and thoughtful design features make it a practical solution for extracting and filling automotive fluids. While it’s not without its minor flaws—such as the limited capacity and occasional plunger issues—the overall performance and convenience it offers outweigh these drawbacks.

Recommendation

I would recommend the Craftsman Fluid Extractor to anyone looking for a reliable and efficient tool for fluid extraction tasks. Its robust construction, ease of use, and practical features make it suitable for a wide range of applications. Whether you’re a seasoned mechanic or a weekend DIYer, this tool can save you time and effort, making fluid extraction a less daunting task. Just be prepared for the possibility of needing to empty the barrel more frequently for larger jobs and occasional minor leaks. Overall, it’s a solid investment for maintaining your automotive systems.
