How to Connect Air Compressor Fittings & What Are the Available Types:
Finding the ideal fitting size is what you should consider first. It’s one challenging task to do if you have no idea at all. But that does not mean you can skip it. There are certain types that will be bringing into the limelight today. And also, a passionate user guide to connecting these fittings will also be served. So, make your plates ready!
Connecting Fittings to Air Compressor:

Let’s first start with brushing up some basics, trust me it’s important. Now if you have owned an air compressor, then there should be a discharge coupler coming along. If there’s no such thing, then you should experience air flowing out of the air-line end. This is when you run the air compressor. Air flows through regulator and goes all the way out to line’s end. The coupler installed will help to not allow air flowing out.
There should be a flap check valve in that discharge coupler part. Sometimes there’s a tiny ball as a substitute. This is the main mechanism that stops air flowing through it. So that you can use until the mating connector is plugged.
As soon as compressor has enough run and tank is almost full, you can easily use the entire air inside. Now let’s move on to the big question. How can you transfer that tank air to the tool?
You need a flexible air-line or hose. Now to connect the air hose there should be connecting devices on both ends. And that’s when you may end up requiring an extra connector or coupler, in short fittings.
Step 1 – Start by Part Observation
The fitting should remain on hose end. Usually, air hoses end come with a threaded male fitting. You need to figure out the type first. By utilizing such easy to connect or disconnect fittings, you’ll make the hose removable. It could be for compressor itself or even the air accessories you want to connect with.
Step 2 – Threading Air Hose
You need to fit the female part into one end of hose tightly next. Use tools to do so with one for the air hose and another to hold fitting. Never try to over tighten it. Now using Teflon tape \ simply wrap other ends after connecting male fitting.
Step 3 – Connecting on Tank
Now use another female coupler fitting. It should be placed on the tank or compressor. Do the same tightening job. Connect the hose’s male fitting with tank’s female coupler. And the connection is made.

Verdict
And that was my take on how to connect air compressor fittings. It’s probably super easy once you figure out information about the particular type of fitting you’re using. Connecting various accessories to increase the efficacy of your air compressor is a valid thing to do.
And the right type of fitting will help you do that in safest and probably best way. Of course, it’s important that you consider the right size that matches what you’re been working with. And once you do so while learning the right connecting method, everything is good to go.
