Buying Guide for Air compressor Regulator

Finding a top-grade regulator for your air compressor will not be easy. It is truer if you want an air regulator with some special features such as an additional pressure gauge.

For your information, many regulators that look promising at the beginning may end up disappointing you later. This tiny sized part of an air compressor usually comes along the compressor itself.

But if it doesn’t, or if you need a replacement, then the regulator must match the compressor. For that reason, it is a wise choice to get a regulator that goes with almost all air compressors. Here is how you can find something like that-

The Size of the NPT Inlet and Outlet

The NPT size makes it suitable for certain air compressors. If the inlet and outlet of an air regulator don’t match your air compressor, then you can’t use that regulator on that compressor. ¼ is a standard size for most regular NPT.

This is the size most air compressors accept too. But some air compressors can have a different size need. So, check your air compressor before buying the regulator.


Your regulator must be durable enough to survive the heat that your air compressor emits. Otherwise, it can easily get damaged. For most tasks, a regulator should have a temp resistance level from 40 to 140-degree F.

Aluminum built regulators are so durable and don’t rust. Brass and cast iron are also two great choices of materials.

Pressure Level

The main reason you are buying the regulator is to set the pressure level of your air compressor. So, your regulator must cover at least up to the max pressure that the compressor sustains. If the regulator can’t tackle that much pressure, then it’s dangerous for it.

Most regulators have a max pressure limit of 175 PSI, which is a safe point. But check the max pressure of your air compressor anyway before making the purchase.

Pressure Gauge

Most regulators have a pressure gauge with them. It is to check the pressure level. In most cases, you get a dialed display. What you need to make sure is that the reading it shows is accurate. If not, then that is a major issue.

Additional Accessory

Many regulators may come with an air filter. This is a bonus trait. If your desired regulator has one, check its stats thoroughly. Keep in mind that they might cost much than regular ones.


One thing you must remember that no matter how good of a regulator you may find if it can’t match the conditions of the air compressor, it’s a lost cause. Meanwhile, the stats of your air compressor also have to meet the requirements of its applications.

So, never buy a regulator before an air compressor. A regulator, if installed tightly, will not allow much leakage. But to completely prevent any leakage, try getting a regulator with an additional sealant or buy one separately.
