In an industrial setting, there are all kinds of reasons why couplers are an important component. From pneumatic lines to water lines to feed equipment, there are often couplers in just about everything. Perhaps one of the most common uses for couplers is to create connections for longer air hoses that can be connected to a compressed air system. Just like any other part, these couplers can wear out and have to be replaced at times. Here are a few often-missed signs of failing couplers in high-pressure air hoses.
1. There are whistling noises coming from the hose.
If you hear a high-pitched whistling noise around an air compressor, you may pay no mind to it all. These kinds of noises are quite common where the use of high-pressure air is concerned. However, if you take a closer listen and see that the noise is radiating from a joint in the hose, it very well might be because the coupler that is making that connection is damaged and needs to be replaced. As air slips out through tiny damage points, you may even hear it before you can actually feel the air coming out.
2. There are spots of moisture around the couplers in the hose.
Most large air compressors distribute air that will have a tiny amount of moisture in it. This moisture comes from condensation and from oil inside of the motor. Most of the time, this moist residue will spill out in small particles with the air at the end of the hose. However, if there are problems with the couplers in the air hose, the moisture can accumulate at these joints and come out there first. You may see tiny wet spots around the coupler or feel like your hands are left oily when you handle the hose at the connection joint.
3. There is a lack of air pressure from the air nozzle.
If the couplers that hold the joints of the hose together are especially deteriorated, it will definitely cause a great deal of air loss. You may not catch on at first, but as the coupler breaks down further, you will likely notice you do not have the same amount of air pressure coming from the nozzle at the end like you really should. Air leaks from a faulty coupler can come out at several small points, so pay close attention to the coupled connection to feel for blowing air and determine if that is the problem.
