How To Replace Air Compressor Hose Fittings?
Today We are here to discuss how to replace air compressor hose fittings. An air compressor has to deal with a lot of air pressure. The pressure has the most direct effect on hose connectivity. The connecting area of the hose is made with a metallic piece and this component gets damaged day by day.
So the replacement of the coupler is pretty much necessary. Because the coupler is the only device that connects more than 2 hoses. Also, the turbulence of the air in the pipe gets well-oriented by the air splitter that is inside the coupler. Follow the whole content to know the methods to replace a hose fitting.
Needed Instruments For The Fitting Job
The air hose fitting job requires some major components. Without those, it is impossible to do the replacement job. The use of those components is described in the further section. But here are some basic information,
A coupler is needed for this job with a definite diameter. The available coupler measurement in the market right now is around 20 to 70 diameter, 50 to 85 mm washer, and 1 to 4 pressure splitter.
Thread or Falcon Tape
This is not an ordinary tape or PVC tape. This is made with falcon based material and it is only used in the thread area of any component. The thread should be 35 to 65 mm wide based on the thread-width.
There are two types of wrench needed for this job. The two wrenches need to be worked together while fitting the hose. The measurement and the objective of each range have been described here,
.57 Unit Wrench:
This wrench is made with cast iron and the compressive load is extended to do the heavy job. This .57 wrench is used to capture the screw or the coupler itself while turning it to the clockwise direction.
.75 Unit Wrench:
This wrench is also made with cast iron but for being small in size it cannot take the extra compressive load. The main objective of the wrench is to hold the screw on the air hose area while fitting.
Step By Step Replacement Criteria
In this section, we are going to discuss the methods for how to replace air compressor hose fittings with details. The first step of this method may not be necessary for you. Because the connectivity of the chuck may not be required. Here are the most basic criterion,
Disconnect the Air Chuck
An air chuck is a long piece of metal that is used to connect 2 or more hoses at a time. But there are 2 types of air chuck available in the market. Both of the air chucks have a different method to be detached.
Single Air Chuck:
The single air chuck has only one gateway which is connected to the mother hose or the main hose. The connectivity can be easily detached. You just need to use the .57 wrench and turn the screw to the anti-clockwise.
Dual Air Chuck:
The dual air chuck consists of a dual gateway and it is the only chuck that can connect 2 or more hoses at a time. Before detaching from the main-hose, it needs to be detached from the auxiliary hose first. The .57 wrench is required for this job.
Use Both of the Wrenches
If you have disconnected the chuck properly, it is time to use both of the wrenches that we have discussed earlier. The 2 wrenches are needed at the time because to separate the coupler, 2 screws need to be turned at a time. The first screw is situated before the main air hose thread.
The second screw is not a real screw, it is the coupler that we are trying to replace from the beginning. The first screw needs a .57 unit wrench and the second one needs a .75 wrench. Both of the wrenches should be-hold at a time while performing a turn on each of the threaded screws.
Addition of Falcon tape
Thread tape or the falcon tape is made with falcon based material which is used to airtight. It is necessary because the 2 connected thread screws cannot have any air gap between them. Otherwise, the air compressor cannot be performed to fulfill its purpose. 2 to 3 mm length of falcon tape is enough for this job.
Replace the Coupler
Now it is time to replace the coupler with the new brought one. The coupler has different measurements and various diameters. So you have to determine your required diameter and components according to your need. Generally, a range of 20 to 70 mm diameter is seen and the splitter is 1/4 units.
For replacing the coupler, you just need to adjust the coupler thread to the mother hose thread. Now the turn should be implemented in the clockwise direction. Make sure the .75 wrench is used to hold the hose screw while turning the new coupler set with the air hose.
After doing all the steps above, you are now ready to use your new coupler. But before that, you need to check if the component is working or not. The main inspecting objective is the air splitter inside the coupler. If the splitter works perfectly after turning the machine on, replacement is successful.
Final Verdict of How To Replace Air Compressor Hose Fittings
An air compressor can be used in many kinds of jobs based on pressure requirements. So the air hose needs to deal with a different type of air frequency as well as force. That is why the coupler has a different functional life for different working purposes. If you have read the whole steps of how to replace air compressor hose fittings, you can do the job easily. You don’t even need an expert for this job.
