    These fittings are important because they are used to connect other tools or accessories to the air compressor. You might not know this, but choosing the right kind of fitting is challenging for most people and not just you. There are so many different manufacturers in the current market, therefore, leaving many consumers confused. Yes, it is great when you have options, but too many options can be a bad thing especially when most of the products turn out to be of low quality.

    Top 5 best air compressor fittings

    This ultimate review and buyers guide on the best air compressor fitting should help you make an informed decision before making any purchases. We will go through everything you need to know about air compressor fittings including factors you need to consider, how to determine the exact fitting sizes, and ensuring you have a strong seal during connections. We will conclude with an in-depth review of the top five best air compressor fittings to help you narrow down your choices.

    Determining the exact best air compressor fittings sizes

    Most people find themselves in that awkward position where they have all the tools and connections, but don’t seem to know the exact fitting sizes that they need. This is especially challenging when you need to fit a new hose or replace a connector.

    Let me start by stating out that most tools use either ¼ or 1/8 inch connectors especially when it comes to contractor and consumer gear. However, this might not always be the case and you need to know how to calculate the right sizes.

    To determine the size of your fitting port, measure the diameter of the port. Make sure it is right across the center and have it in inches. Once you have the right measurement, you will know the pipe size and therefore finding a replacement will be relatively easier.

    How to get a strong seal when placing new fittings

    When attaching any hardware to your air compressor using new fittings, you need to ensure that you use the right thread size and crate a robust seal. This is usually challenging to most consumers especially when it is there first time dealing with fittings.

    The process sounds difficult, but it is relatively simple once you know how to achieve a strong seal. The easiest way to get a strong seal is by attaching a Teflon tape into the thread. Yes, sometimes you might adhere to the exact standards required but there are always chances of air escaping through the fitting. The Teflon tape helps to create a tighter seal that lasts until you need to replace the fitting.

    Ensure that you wrap the Teflon tape in such a manner that it covers the male thread but does not overlap the connector’s end. The Teflon tape should equally not extend to the thread end because the high pressures might just it dislodged which will cause blockages in the long run.

    You must ensure that you use just enough of the Teflon tape for a more effective strong seal. Just ensure that you don’t use excess or overlap the tape which will cause blockages. When wrapping the male connector with Teflon tape, you must exercise precision. Take your time and ensure that you get the job done effectively. A strong seal will ensure that your air compressor works effectively and efficiently as required.

    Is Teflon tape packed with couplings?

    You might have come across some air compressor fittings already packed with Teflon tape. This is not unheard off and some manufacturers actually prefer doing this. However, there are also some couplings that come with a sealant within them. This sealant is some kind of paste or putty that creates the perfect seal when working with connectors. Ensure you go through the product description to determine whether you will need a Teflon tape or not.

    Most air compressors from the leading brands come with the sealing paste already in the fittings. However, when doing any replacement, ensure that you clean off the excess sealant before wrapping a new Teflon tape.

    Things to consider when choosing the best air hose quick connect

    Finding the right air compressor fittings is not a simple task and you should not just pick from a revised list. You really need to take your time and understand all the individual fitting features and how they work. When it comes to choosing the best air compressor fittings there are certain considerations that you need to have in mind.

    1. Fitting port size

    Just as stated earlier, the fittings have to be airtight. Get the right measurements as explained earlier and getting quick-connect fittings should not be a problem. Understand that if your tool has been in use several times, then the standard ¼ and 1/8 inch might not fit correctly.

    Since you already know the fitting port size, finding the best air compressor fittings should not be too difficult. As stated earlier on there are several options in the market to choose from. Start by eliminating all the options that are not an exact match for your fitting port size. This should give you a base on where to start.

    2. Automotive or industrial air fittings

    Labels usually leave many consumers confused especially when it comes to air compressor fittings. Some are labeled industrial while others are labeled automotive, and this is a huge challenge. One simple look at these two labels and most people start panicking.

    In reality, however, there is no difference between automotive and industrial air fittings. Both of the labels simply indicate compatibility when it comes to the standard measurement. This means that the label should not make a difference once you have the right size. Remember that compression fittings are accessories and it, therefore, doesn’t matter whether they are automotive or industrial.

    It comes back down to the measurements. As long as your measurements are correct both automotive and industrial air fittings will work just fine.

    3. Color coding

    When shopping for air compressor fittings, you will notice different color coding. Contrary to popular belief, this is not to beautify the product but rather indicate the different fitting types. Industrial air fittings are red and referred to as type D. ARO fittings are green in color and referred to as type B, while the automotive fittings are blue in color and referred to as type C.

    You must, therefore, pay a keen interest in color-coding when choosing the best air compressor fittings. In most cases, however, the product description will indicate whether you’re purchasing an ARO, industrial or automotive is fitting.

    4. Material

    The best air compressor fittings should be made from a material that is rust-resistant and non-corrosive. This is very important because you need the fitting to be long-lasting and not something you change periodically.

    Ensure that the material used to manufacture the air compressor fitting is either brass or steel. We need these fittings as long-lasting as possible because replacing them often might lead to problems with your air compressor. Also, remember that these fittings cost money, and we don’t want to spend money more often that we need.

    Frequently Asked Questions and Answers about Air Compressor Fittings

    What are air compressor fittings used for?

    The air compressor fittings are used to connect compatible tools and lines an air compressor. These air compressor fittings, therefore, need to be of high quality and standard. Compatible tools and lines will work effectively when connected to the air compressor with the right fittings.

    Must I get a regulator along with the fittings?

    You don’t need to get a regulator, but it is very important in helping to maintain low-pressure levels. In an ideal environment, you should always use the lowest pressure on your air compressor so that it might last longer. The good news is that regulators are not expensive and will cost you just a little bit extra. Remember that it is, however, not compulsory and you can work without it. I would recommend that you get one if you don’t have one.

    Should I use Teflon tape?

    Yes, always use Teflon tape as instructed in this buyer's guide and review. It is true that some fittings are airtight, but it is equally important to be safe than sorry in the long run. Teflon tape is a good way of ensuring that your fittings are airtight and they are relatively simple to use. Go to your local hardware store and purchase Teflon tape should you not have one already in your home.

    What is the standard hose pipe size?

    Universally, the diameter of a standard hose pipe should be ¼ inches while the length is about 50 feet. Remember this is the universal standard size but is not true for every manufacturer. Some manufacturers have hose pipes with different dimensions according to customer preference. The good news is that the sizes are always indicated in the product description.

    What is the difference between an automatic coupler and a manual coupler?

    When dealing with a manual coupler, you will have to pull back the sleeve before inserting the plug. With the automatic coupler, you simply need to push it in and it will connect by itself. This is the only difference between an automatic coupler and a manual coupler.

    How many times does my air compressor need to be serviced?

    This will entirely depend on how often you use your air compressor. As long as you don’t have any leaking problems with your compressor fittings, then servicing once a year will do. However, when it leaks irregularly then you need to perform servicing every two months to ensure your compressor is working effectively.
