While copper pipe and fittings are still common, many professional plumbers now use flexible PEX for all new construction and in repairs and extensions to existing copper systems. PEX is especially friendly to DIYers, who find the various methods of making connections much easier than soldering copper fittings with a torch.
Can PEX water tubing be used underground?
Pex tubing, as well as the pipes, can be used in high temperatures to high pressure, and also polyethylene makes the pex much suitable for underground plumbing works. However, in certain cases, the material of pex tubing can degrade, but it will serve its purpose for more than a hundred years.
Can you use PVC piping for compressed air?
Unfortunately, OSHA has banned PVC and CPVC piping for use in compressed air systems. The reason OSHA does not allow PVC or CPV in compressed air piping is that these plastics are not strong enough to withstand high-pressure applications such as compressed air distribution. In addition, these plastics will degrade when they come in contact with oils and lubricants from the air compressor, leading to fractures and splintering.

ABS, PE and HDPE plastics are appropriate for use in compressed air piping systems and have some benefits over metal. The materials are lightweight and easy to work with, requiring no special bracing or supports. Plastics can be easily cut and fit using standard tools and can be glued together rather than welded.
Can you use PVC pipe for compressed air lines?
The use of PVC pipe is common but NOT RECOMMENDED for use with compressed air. It is often used because it is readily available, inexpensive, and easy to install. However, as with many plastics, PVC gets brittle over time and can crack, break, or even shatter.
Where is PEX not allowed?
You can't install PEX in high heat areas like near recessed lighting. This also means you can't connect PEX directly to a hot water heater, but you can use a connecting material to do this. PEX is semi-permeable, which means liquid can enter the pipe. When it comes to safety, PEX isn't antibacterial.

How Do You Make PEX Connections?
In order to make either watertight or airtight connections with your PEX pipe, you will need to obtain the right tools and supplies. I will provide you with five methods for connecting the pipes. The fittings and connectors must be an exact match to the size of the PEX pipe.
What is the strongest PEX tubing?
PEX A is the strongest, most durable, and most flexible of the PEX types. It boasts a unique ability to recover from kinks that others may find difficulty in. Normally, if a section of the tubing becomes damaged or deformed, you’d have no choice but to remove and replace it.
How to connect PEX tubes together?
The stainless steel clamps method of connecting PEX tubes together involves using a ratchet clamping tool to tighten stainless steel rings around the PEX connections. Similar to the copper crimping method, the steel ring is slipped over the PEX tube before the fitting is inserted. The ratchet clamping tool is then used to squeeze a tab on the ring, which then tightens the ring securely around the tube and the fitting.

Yes, many people use PEX for compressed air lines, however this should come with the realisation you’re using something for which it’s makers do not recommend, approve or condone.
Why is PEX pipe used?
PEX pipes ensure fresh, high-quality air as there is no risk of corrosion or release of flakes. Many pipe tubing, such as galvanized pipes, needs to be repaired due to flaky materials disposed of in the pipes. And this is where PEX takes the lead. They provide you with clean, fresh, and pure-quality air for long-term use.

Why is PEX tubing kinking?
The usage of PEX airlines is now being promoted but one major issue that disturbs the work quality is kinking. Because PEX tubing is quite flexible, so it can easily bend and form kinks. These kinks can create weak spots and result in leakage of air.
What is the easiest pipe to install?
For instance, CPVC and many other plastic pipes require proper glue or cement for efficient fittings and connections. On the other hand, PEX is the easiest to install as strong connections are made using crimp fittings .
What is the best temperature for PEX pipeline?
The best thing about PEX pipelines is that they can sustain high temperatures up to 200°F, whereas an ideal operating temperature for air compressors is between 50°F-94°F. So, when it comes to bearing high-temperatures, PEX can provide you with maximum output.

Also, humid air can help rust and corrosion occur in the compressor and all metal components if they are found in the pipes of your system. That is why it is important to dry the compressor, as well as all filters regularly.
Can PEX pipes be used for compressed air?
The most important thing is to follow the advice of more experienced, use the information you read about the use of PEX pipes for com pressed air lines and prevent any possible problems that may occur, which leads to additional costs and new problems that repair or installation of a new system can bring.
Can PEX pipes be exposed to UV light?
To be honest, PEX pipes do not tolerate sunlight or UV rays, which is why you should avoid outdoor installation and exposure to these lights.
Can PEX pipes be placed on walls?
Due to its elasticity, very often PEX pipes can be placed where it seems significantly more difficult to install solid, rigid pipes such as finished walls and ceilings of buildings.
Can PEX pipes be used for ventilation?
You have to take into account that it is very possible that the pipes will let very small amounts of air through the joints, which can reduce the efficiency and quality of your air lines , but this is a risk you take before starting the ventilation system when working with PEX pipe s.
What is the function of metal pipe?
One of the functions of metal pipe is to cool down the hot air as it comes from the tank, and draw mositure out of the air. That's why the horizontal runs are all supposed to be sloped toward a drainage point, all vertical runs have drainage valves at the bottom, and all horizontal-to-vertical tees (and vice versa) have 8" vertical risers.
What is the argument against rigid PVC?
The argument against rigid PVC are: 1.) is loses strength quickly when heated, such as by hot air; 2.) a potentially catastrophic failure mode would send shrapnel flying."
Does Pex conduct heat?
Pex wouldn't conduct heat nearly as well, so probably does not perform the moisture-condensation function as well.

And if you have to move anything around tomorrow....no problem. Disassemble, and reassemble in minutes. cabinetmaker/college woodworking instructor. Cape Breton, N.S
What is PEX polyethylene?
PEX is a polyethylene product that has undergone a chemical change in its molecular structure. The polymer chains in the PE product that are used to make PEX are cross-linked which makes them more flexible than other kinds of lines.
How much pressure can a PEX tubing hold?
PEX can hold a burst pressure of up to 800 psi. This is actually two times the requirement for ASTM F876, which is the standard specification of the PEX tubing. That being said, this is a product that is made to handle water pressure and not compressed air pressure.
Why does PEX crack?
Being flexible and prone to cracking and stretching, PEX can sometimes have trouble holding compressed air and experience breaks or cracks due to the pressure within the PEX lines.
How to crimp a PEX ring?
Crimp the ring just like you did with the other end of the PEX line. Turn on your compressor and make sure that you do not experience any issues with leaks or other problems.
Why is air compressor piping so lightweight?
This is because this kind of piping will not corrode and it is resistant to leaks. It is lightweight and easy to bend as needed and install. It also provides superior connections with the air compressor fittings.
