Two types of check valves can be installed in an Air Suspension

Air suspensions are gaining popularity every day. Installing a set of airbags or air cylinders can be simple enough to be installed at home, but it's important to do it right. One of the safest add-ons that you can make to an air suspension is adding check valves. A check valve allows air to only flow one way in an air system. Why is that important? Because if for some reason you lost pressure in a line, the entire air system would not evacuate, allowing you to either pull over to the side of the road, or get a jack under the truck to fix the problem. Installing check valves isn't complicated; it just takes some time.

There are two different types of check valves that can be installed in an air suspension, the only difference is how they mount. One style has male pipe thread on both ends, and the other has female pipe thread on both ends. Depending on how your air system is plumbed, one of these may be better than the other; it just depends on your specific setup. We'll start with a completed valve assembly and, for this example, will be using the male pipe thread style Wafer Check Valves.
