What does oxygen barrier mean in PEX pipe?
PEX-AL-PEX is constructed the same way with an aluminum lining, making it an oxygen barrier pipe as well. This plays a major roll on the tubing’s ability to function without corroding ferrous materials in the system, and allows many other advantages that the Non-Barrier tubing does not have. Due to its oxygen barrier the tubing can be used ...
Do I really need oxygen barrier PEX?
If you're using a closed system, you MUST use oxygen barrier pex... Or else your system won't be closed...... Now, on open systems, it's a little less critical.... Basically a good anti-corrosion additive is in order there if you have ferrous (iron based) materials in the system.
What are the standard sizes for PEX tubing?
Pressure ratings, testing and pressure drop
- Maximum working pressure indicates highest anticipated operating pressure.
- Pressure testing requirements and procedures should be in compliance with local codes and PEX manufacturer’s instructions.
- Air pressure testing is recommended over water for practical reasons and due to difficulties arising from water freezing during winter months.
Can you use oxygen barrier PEX for potable water supply?
The initial investment in the PEX tubing with oxygen barrier can help you in staying in good health. Therefore, always use pipes with oxygen barrier for the supply of potable water. Nothing is better than PEX.
What is oxygen barrier PEX pipe used for?
radiant floor heatingPEX Tubing with oxygen barrier is used for radiant floor heating, ice/snow melting projects and baseboard/radiator heating applications. It is also commonly used for supply and return lines to boilers and fan coils.

How do you know if PEX tubing has oxygen barrier?
Both Oxygen Barrier and Non-Barrier PEX can be purchased in these assortments of colors. The difference is in the outside material of the tubing itself. The Oxygen Barrier tubing exudes a glossy appearance, as the Non-Barrier tubing resembles a matte.
Do you have to use oxygen barrier PEX?
PEX without an oxygen barrier actually allows oxygen from the air to permeate it. This happens even if the PEX is embedded in concrete. Cast iron circulator pumps will rust when oxygen is present in the water. Bronze or stainless steel circulators are necessary when this is the case.
Can I use oxygen barrier PEX for domestic water?
Oxygen barrier PEX is made for heating applications and has thus not been approved for plumbing and drinking water.
What color is oxygen barrier PEX?
PEX with an oxygen barrier is designed for closed-loop space heating systems, and will normally be either red or white. It is usually not approved for use with potable water.
What is the difference between PEX A and PEX B?
Flexibility - PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance - PEX-A has the greatest resistance, PEX-B the lowest.
What is the difference between red and blue PEX?
PEX Particulars Although there are three types of PEX (see Label Lingo, below), the different colors don't connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold. Red PEX pipe carries hot water. Blue PEX pipe carries cold water.
Can red PEX be used for radiant heat?
Yes, PEX pipe is approved for radiant or hydronic heating applications. Since ferrous components are likely to be present in the system, it is important to use oxygen barrier PEX pipe to help prevent ferrous components from rusting.
Do I need oxygen barrier PEX for outdoor boiler?

Then I do strongly suggest that you use an oxygen barrier pecs to ensure against future useMoreSystem. Then I do strongly suggest that you use an oxygen barrier pecs to ensure against future use which might not include an open system for the boiler.
Which PEX for potable water?
Most plumbing applications, especially those involving potable water, call for the use of non-oxygen barrier PEX, offered in several grades. PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures.
What is a crimp connection?
Crimp Connection System - Brass Crimp Fittings (manufactured to ASTM F1807) or Poly Crimp Fittings (manufactured to ASTM F2159) and Copper Crimp Rings (manufactured to ASTM F1807) in conjunction with PEX Crimp Tools.
What is the most common type of tubing used for radiant heat?
The most common type of tubing used for radiant heat applications is the oxygen barrier PEX. The oxygen diffusion barrier coating of this radiant heat PEX prevents the oxygen in the atmosphere from permeating the pipe walls into the water to avoid over-saturation of the water with oxygen. For cost reasons, many of components in a typical radiant/hydronic heating system - from circulator pumps to heating elements and piping of the boiler are either cast iron or ferrous and are subject to rusting when in contact with oxygen. Without the oxygen barrier, only components made from non-corrosive material (such as stainless steel, brass, bronze) can be used in the system, subsequently increasing the costs of its initial installation and further maintenance.
What is the difference between PEX and non-barrier?
Primary difference between Non-Barrier and Oxygen Barrier PEX is external coating of special polymer (EVOH), which purpose is to prevent gradual diffusion of O2 (oxygen) molecules into the water circulating in the heating system. This simple mechanism protects cast iron components of the heating system from rusting and contributes to higher operating efficiencies and longer lifespan of the parts.
What is 1" PEX?
1" PEX is generally used for supply and return lines to the boiler or the radiant heat manifold. Large internal diameter of 1" PEX allows it to transport substantial amounts of hot water to great distances, which makes it ideal for outdoor wood furnace installation.
What are the components of a radiant heat system?
For cost reasons, many of components in a typical radiant/hydronic heating system - from circulator pumps to heating elements and piping of the boiler are either cast iron or ferrous and are subject to rusting when in contact with oxygen. Without the oxygen barrier, only components made from non-corrosive material (such as stainless steel, brass, ...
Differences Between Oxygen Barrier And Non-Barrier PEX Tubing
Anybody can explain to me what is real difference between two type of polyethylene, both are cross linked, seems have same color, same structure.
Comments (13)
Oxygen barrier has an interior coating of EVOH (ethylene vinyl alcohol) polymer which is less oxygen-permeable than the polyethylene of the tubing.
What is PEX piping made of?
Traditional piping would be made from copper or a galvanized metal. PEX offers a modern alternative with a material that’s more affordable and much easier to handle.
What is PEX plumbing?
PEX is a practical alternative to traditional plumbing that offers a range of benefits. If you’re a DIY plumber, this is the material you want to be using, and hopefully, this article has given you everything you need to know about PEX.
How to fit PEX pipe?
Once you’ve cut the PEX to the appropriate length and removed the old pipe, you can fit your PEX plumbing. Slide a crimp ring over the end of your PEX pipe, and then use the cinch clamp to tighten the connection. Make sure this is completely sealed before you switch the water back on.
What is non-oxygen barrier?
Non-oxygen barrier PEX is simply PEX without any kind of oxygen. This is used for potable (safe to drink) water. There are two grades of non-oxygen barrier PEX to choose from, each with slightly different qualities:
Why is it important to do plumbing yourself?
Doing it yourself lets you save money and time, and prevents any reliance on busy professional plumbers. DIY plumbing has become more accessible because modern materials are now readily available. Traditional piping was made from copper or galvanized metal.
What is oxygen barrier PEX?
Oxygen Barrier PEX is used in your heating systems which can suffer from corrosion, and just like with Non-Oxygen PEX, there are two grades available. Oxygen Barrier Pex is typically ½ inch in diameter, but you can get some variation to fit different systems. 3. Aluminum Barrier Pex.
What is an aluminum sandwich?
This sort of 'aluminum sandwich' is useful because it means that the PEX holds its shape once it’s bent into position without any need to secure it. It offers an oxygen barrier and is well suited for high or low temperatures because of its low expansion rate.
