How to Replace Air Compressor Hose Fittings? – Complete Guide

An air compressor is worth hundreds of bucks and no one wishes to replace the whole unit only because of hose fittings. Even if someone is, it isn’t wise at all, right? Specifically when we are here to assist you on this matter. Further, if you want to devote this device to your personal store use, you need to put compressor hose fittings into consideration. 

Therefore, how to replace air compressor hose fittings is a must-know thing. We understand that and that is why we are here with the simplest steps to guide you through the whole process. These uncomplicated steps are your ultimate key to saving money. Let’s get to that straight. 

Replacing Air Compressor Hose Fittings- A Complete Guide

Most of the air compressors come equipped with hose fittings in a single-style size. It varies from brand to brand and model to model. Therefore, you must be well aware of which hose fittings your air compressors employs. 

In addition to that, there are multiple other things which you should put great thought into while replacing the hose fittings. From getting the perfect equipment to set up things the right way, utmost care and consideration are demanded. Let us guide you through all that. Let’s get started! 

1. Getting Yourself the Right Tools and Other Equipment

All the connections involved in the air compressors, as well as the hose fittings, work through a certain method. This method is in strong adherence to the NPT fittings and cannot be ignored. NPT is a standard set that stands for national pipe thread tapered. It is strongly advised to strictly follow the standards as laid out by NPT. They define standards that involve the fittings together with the pipes. 

NPT standard is to make sure that all the fittings and pipes which are used in the machines follow the same size. This will make the design consideration simpler together with enhancing the vaoalbility of the parts. This way all the fittings will be compliant with each other and the fuss of finding the specific part will be greatly eliminated. This generally applies to all the couplings including the ones that are already installed with the air compressor. 

NPT standards are strict and thorough. Not only are these applied to the connectors but also to the inside threads. Thread size plays a prime role as the fittings are highly dependent on that. It is required for perfect coupling. The noncompliant coupling will contribute to air loss and will cause difficulty in building up the right pressure. It is quite obvious that wrong thread size will contribute largely towards decreased efficiency, poor performance, and undeveloped airflow. 

It is quite simple to identify the correct fittings. Further, one can simply find the one that matches the requirements of their air compressor. It is still encouraged to be acquainted with NPT fittings in order to avoid any inconveniences. It plays a prime role when it comes to connectors as well to other fittings. 

2. Setting Air Compressor Hose Fittings

You will be having several components and connectors along with functioning parts. However, there is an important thing which you are completely missing on. Yes, the initial prime paperwork. This is significant in determining the correct size of the hose fittings. This can have a great effect on the air compressor performance and you can not neglect that. Therefore, this becomes a major concern when you opt for installing new hose fittings or replacing the old ones. 

Talking about the consumer equipment, the tools which are fairly common are connectors of the size ¼ or either ⅛ inches. However, this largely depends upon how old the air compressor is or how it is composed. These factors must be taken into account as well. This will ensure that the sizes you select are accurate. 

Therefore, you need to determine the port opening. In order to do that, you need to perform scale calculations. To evaluate that, you simply determine the opening depth.  Make sure that the calculations are made for the exact center of the harbor. This way you can determine the accurate sizing and you will be able to identify which connector will work adequately with the air compressor. Simple, right? 

3. Sealing the Air Compressor Hose Fittings Tightly

Replacing the mounting which connects the compressor with the air tank comes with a huge responsibility. So is the case with fittings that are placed on the case of the tool. In case you do any of these, you have to ensure that you have the accurate size wire which will serve to connect them perfectly. In addition to that, you cannot forget the seal tight grip. The grip should be perfect while you connect the parts which make the hardware. In order to ensure that you have connected the parts well and sealed them perfectly and tightly, you are required to use Teflon tape. 

While you can perfectly adhere to MPT standards and rules, there is a chance of leaking always being prevalent. Therefore, you have to eliminate that, no matter how accurate your fitting size is. The question arises how can you do that? The answer is pretty simple. That can only be done through the use of Teflon tape. Moreover, you cannot just use it as you wish, there is a specific method of using it. The use of Teflon tube will contribute to integrity in the connection as it brings them perfectly close. 

4. Use of Teflon Tape- Explained 

Teflon tape is a great and effective way when it comes to perfectly seal the connections. The tape lets you achieve a closed fit connection. However, one needs to ensure that they are putting the tape at the right connection so that no issues arise. Ultimate caution is always needed. The tape has to be wrapped around the connector corresponding to the male one multiple times. It, however, should not touch with the end which is the basic connection part. 

It is also advised to remove any excess air that interferes with the connection end of the connector. This is due to the reason that the air compressor will develop high pressure in the pipes. This will result in the disintegration of the Teflon tape, specifically where there is excess tape. This might result in blockage which is obviously undesirable. Even if it doesn’t contribute to complete blockage of the pipes, it may result in partial airflow restriction. This restriction will correspond to poor performance and reduced efficiency. Therefore, one ought to be very careful with Teflon tube usage. 

Frequently Asked Questions

1. How do you change a nozzle on an air compressor?

You can change the nozzle by releasing the pressurized air followed by unscrewing. Finally, you are required to wrap a tape, Teflon, by moving it clockwise. 

2. Are air hose fittings universal?

Yes, air hose fittings are universal too but usually, manufacturers like to use single-style ones. 

3. When do the air compressor hose fittings require replacement? 

When you notice some wear and tear on the hose fitting then it is the best time to replace the fittings.
