How To Buy The Best Piston Ring Compressor
Just like any other engine part or accessory, a lot of piston ring compressors are available for purchase. You have to choose from several models and variants, which can be very confusing. Plus these varieties all come in different qualities. Of course, you need to eventually arrive at the best out of the multiple options for top efficiency.
Let’s find out some important factors and qualities to look out for when buying the best piston ring compressor:
1. The Type Of Compressor
A good piston ring compressor, to a large extent, depends on the type. As we had said earlier, there are 4 broad types of compressors. Each of them offers varying degrees of functionalities.
Some questions you should answer before finally making a choice is, does the compressor require clamps, ratchets, or pliers? Also, make sure the overall quality and structure of the piston ring compressor tool are reliable before spending your bucks.
One awful reason people end up buying something unreliable is that they look to buy something cheap. But it’s always better to spend a little more to get a tool you can trust!
While considering the best piston ring compressor, you shouldn’t ignore looking out for user-friendliness. Ensure the compressor tool is foolproof and can tolerate possible mistakes without undermining the quality of your piston ring installation. Most tapered tools fall into this category because they’re easy to use and designed to prevent you from making unnecessary errors during installation.
Moreover, some versions of piston ring compressor tools are typically used with pliers to guarantee easy and comfortable handling, with better installation efficacy and reduced strain.
In a nutshell, no matter the tool you decide to buy, ensure the user-friendliness and ergonomics are top-notch.
Of course, some people intend to buy piston ring compressors for short-term usage. But as long as you seek something that’d last for as long as possible, then you need to go for a well-structured tool built strong enough to stand the test of time. Of course, this is even if it means paying a little more for the superior quality.
It also won’t be a bad idea to go for a piston ring compressor that includes a self-locking ratchet which helps prevent premature discharge.
4. Surface Safety
Safety always comes first; hence, another top consideration to make to arrive at the best piston ring compressor is surface protection.
We typically recommend tools that are made of pure steel, as they offer improved surface protection. Many other high-end tools are quite reliable in this regard, although they are more pricey.
5. High Precision And Compatibility
This is probably the number one factor to pay attention to if you want to end up with the best piston ring compressor. Before you make any purchase, you have to ensure the model you’ve selected suits your application.
Before making your choice, it is critical to consider the piston size (diameter). If you are looking to install pistons (and rings) in a variety of cylinder bore sizes, we recommend going for compressors with different-sized bands.
You can also go for any other piston ring compressor, provided it’s adjustable to effectively hold the pistons you’re looking to install. The whole aim is to achieve a very high precision, which makes installation as easy and as accurate as it can get.
Any of the products on this piston ring compressor review can easily be your choicest pick. It completely depends on the type of tool you prefer; the functionality you crave, and the budget you’ve mapped out.
We always recommend superior quality products that offer wide compatibility, work efficiently and precisely, don’t damage piston rings, and above all are durable enough to resist heavy-duty usage — Even if it means paying a little more. That’s why our best piston ring compressor (premium package) remains Alltrade — 940387 Piston Ring Compressor KIT69.
However, if you want to spend a little less on a good piston ring compressor, then YEHAM 3″ Piston Ring Compressor Tool would certainly be a great pick.
Hope you found this piston ring compressor review helpful?
NOTE: Any other piston compressor tool you might prefer from the above list other than our editor’s top recommendations is also quite reliable because we enlisted all the products after broad-spectrum research.
FAQs About The Best Piston Ring Compressor
1. What Is The Best Type Of Piston Ring Compressor?
Ans: The best piston ring compressor type largely depends on individual preference. While some prefer the wrinkle bands due to the multiple options they provide, others prefer the ratchet roll since they are cheaper. But in all, the tapered piston ring compressor works extremely well, because it’s strictly made for a particular piston size. However, you are required to buy a new tapered tool for each piston size you are looking to install, which is VERY fairly expensive.
2. Can’t You Install Pistons Without A Ring Compressor?
Ans: The simple answer is YES, you can install pistons without ring compressors. However, you stand a chance to misplace or damage the rings during such installation. You might also install the piston incorrectly, which could pose serious damage not only to the cylinder block but the entire engine.
3. Can You Run An Engine Without Piston Rings?
Ans: Pistons are normally manufactured and packaged without rings. The rings are only required during piston installation to ensure efficient engine performance. For an engine to work without rings, the piston must be the same size as the cylinder bore and must remain so operationally (which is virtually impossible).
4. What Causes Piston Rings To Fail?
Ans: Piston rings fail for many reasons including a wrong grade of cylinder oil or contaminated fuel oil. But the most common reason piston rings fail is the detonation of fuel from a leaky injector or the interaction of fuel with dirty air.
