How to Fix a leaky Air Compressor hose

Air compressor hose leakage is regular problem in air compressor systems. But the repair can be time-consuming and costly if you apply the wrong method. So, learning how to fix a leaky air compressor hose properly is the key here. Don’t worry; we will guide you to solving the problem like a pro.

The air compressor is the busy part that transfers compressed air from the air compressor to the air tool to complete the desired task. It also makes the air device versatile and often causes leaks during duty contact with different sharp materials. So, fixing a leaky compressor hose is among the regular maintenance for a handyman. But people often damage the whole house due to a lack of proper knowledge.

Guides to fix a leaky air compressor hose

Luckily, the guide will offer a straightforward and quick way to solve the issue. Besides, the reader will learn how to detect air compressor leaks and effectively keep the air compressor from leakage.      

Tools Required: 

Before proceeding, make sure you have collected these tools:

  • A coupler and 2x hose clamps
  • Flathead screwdriver
  • Plastic bag
  • Cutting knife or other appropriate sharp
  • Air hose repair tape 

Locate the Leak

Firstly, identify the exact point of leakage in the air compressor hose. If you find it at the joint, then it would be better to replace the hose. But if you locate the leak in the length, then continue reading.

Cut the Hose

Now cut the hose at any side of the leak using a sharp knife or other suitable hose cutting tool. Make sure you have to make a clean cut as it is essential to complete the process perfectly. If the hose is too thick for you to cut, then ask for expert help.

Place Coupler Fitting Inside Hose

Then take two Air Compressor hose clamp and attach them to the two Air Compressor Hose ends. Now fit a coupler into both the cut hoses. If you find it hard to put the coupler in the tube, heap it up to the end of the hose about 1/2′′, using a lighter to complete the task easily. Once you have put it in, tighten the hose clamps so they can securely hold the hose and fitting. But don’t tighten excessively as it can break the hose clamps.

Wrap plastic bag around

It isn’t compulsory, but wrapping a plastic bag around the mid connection will prevent the hose fitting from getting stuck during use. Plus, hold the plastic bag in place by wrapping it with electrical tape.

Final Checks

Once you have completed all the steps, reconnect the hose to the air compressor and start the machine. Now look at the repair carefully and, hopefully, you won’t find any leaks anymore. If you find it, then check the joint again and tighten it if needed.

Pro suggestion: Buy one of the best air compressor hose repair kit without compromising on the cost to ensure improved repair work. If you find multiple leaks in the hose, it is best if you replace the hose with a new one.

Different ways to find out if an air compressor leaks

Leakage in the air compressor lowers the speed of air pressure and quickly reduces the compressed air capacity. As a result, it causes extra money and energy to refill the lost pressure. The following are some methods of finding air compressor leaks that will help you detect the affected area quickly. So you will have a chance to apply for maintenance and repair work where necessary.

Unloaded cycling

Run the air compressor at maximum speed without any output demand and calculate the time length between the pressure drops and the power back on. You will find a clear sign of ear removal in the system. However, some air release is common even if it is the most solidly maintained compressed air pipeline. So you should measure the percentage of lost air by comparing the air compressor activate time and each load-unload cycle duration.

Pressure gauges

A pressure gauge is an effective tool that helps check the leakage in the compressed air pipeline easily. If you find the pressure isn’t considerable and if the loss is over 10%, you have to take a step to fix the problem in the system.

Equipment and connections

Any connection between pipelines or other parts is mostly causing the compressed air leakage, so start checking from here. Remove unnecessary equipment and isolate the stop valves at those joints. Then make sure that the air hose connection is properly sealed. If you find anything wrong, then replace its connectors and valves or add some thread sealant to the affected area.

Sonic detectors

Escaping air generates a high-frequency hissing sound that is harder for a man to detect. Using a sonic detector can be helpful in such a situation. It will scan the pipeline and display the frequency on the screen by converting it. The leak is as big as the signal is clearer. This method will help you measure the number of problems and get the leakage back to suitable levels.

The bubble test

This method is classic and still acceptable in workshops and industries across the world. Spray a soap solution in the suspected area of the pipe and you will find air blowing bubbles if there is any leakage. It’s a classic process, but it is still famous for its easy and faster operation.

How to prevent air compressor from leakage

 Regular observation is the best way to keep the air compressor from leaking. Apart from this, walk around the compressor plan while it is to check if there is any problem. The following worklist will help you keep the compressor from leakage and ensure quality performance: 

Tighten the connections: A loose-fitting is the main reason for air leakage. So it is advisable to tighten the joining points regularly. The more you secure the system, the less compressed air leakage you will enjoy.

Repair or replace the equipment: The older parts, like lubricators, filters, and regulators, are the more risky spots where leakage can occur easily. To secure the system, repair or replace these parts quickly. A smaller repair like replacing the regulator can ensure the efficient running of the air compressor.

Replace the hose and tube sections: Air hoses and tubes also tend to leak air. However, it is harder to find the leakage in this area, but by applying the air bubble method you can get success. If you find the leakage, replace the hose or tube with a new one to make the air compressor in good shape.

Replace the hose and tube sections

O rings and valve seals: The rubber parts of the air compressor, like O-rings and valve seals, can crack easily due to the consistent heat and pressure. These can be a smaller part of the air compressor but can’t maintain a good seal and start leakage over time. Replacing these components regularly will help you prevent air leakage.

Tighten fasteners: This method of preventing air leakage is a bit time-consuming, but still effective for increasing the longevity of the air compressor. The motor can get weak if the internal part starts shaking due to the loose screws and fasteners. If you hear extra noises or find any shaking parts in the motor, tighten them immediately to prevent any danger as well as air leakage.

FAQs on How to fix a leaky Air Compressor hose

Is a compressor hose repairable?

As long as the compressor pipe doesn’t cause plenty of leaks, it can be repaired. Simply follow the process we have mentioned above to ensure proper repair of the compressor hose. But if the hose has multiple leaks, then you should consider a new one regardless of efficient pressure.

Is Teflon tape effective for preventing air leaks?

Teflon tape is good, but it can get into valves and stick them. If nothing is hanging past the threads, the Teflon tape won’t cause an issue. Instead, you can use Permatex Thread Sealant as it can stop air leaks completely.

How tight should air compressor fittings be?

Tighten the compressor fittings with your hand and snug them gently. Tightening too much can break the fitting and jam it. Besides, it can be hard to replace.

Final words

The leakage of a compressor hose is a common issue that can be detected and fixed. Hope now you can deal with the task effortlessly since you have learned how to fix a leaky air compressor hose. Despite this, it is worthwhile to routinely check the air compressor so you can find and solve the problem in the initial stage. And make sure you have placed the parts with top-quality ones to enjoy longer and more reliable service.
