Cross-linked polyethylene, commonly abbreviated PEX or XLPE, is a form of polyethylene with cross-links. It is formed into tubing, and is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and insulation for high tension (high voltage) electrical cables. It is also used for natural gas and offshore oil applications, chemical transportation, and transportation of sewage and slurries.

In the 21st century, PEX has become a common alternative to polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) or copper tubing for use as residential water pipes. PEX tubing ranges in size from imperial sizes of 1/4-inch to 4-inch, but 1/2-inch, 3/4-inch, and 1-inch are by far the most widely used. Metric PEX is normally available in 16 mm, 20 mm, 25 mm, 32 mm, 40 mm, 50 mm and 63 mm sizes.


Almost all PEX used for pipe and tubing is made from high density polyethylene (HDPE). PEX...

You can run PEX line as you would in a conventional plumbing system, with 3/4-in. main lines and 1/2-in. branch lines. You can also use a “manifold” system, where you run a 1/2-in. line to each fixture from a central spot.

Run your main lines first. If you're running PEX through joists or studs, drill 3/4-in. holes for 1/2-in. piping and 1-in. holes for 3/4-in. piping. Have a helper feed the line to avoid kinks and snarls. Some manufacturers recommend adding abrasion clips at each hole. You must use them for PEX that goes through metal studs, and nail protection plates when the tubing runs within 1-1/2 in. of the face of a stud or joist. Once you've run your main line, go back and mark the location of each branch line, leaving a 1-in. gap for the barbed...

Hey it's Mark from SupplyHouse.com and this is Rifeng oxygen barrier PEX tubing.

This PEX-b grade tubing is designed for use in closed-loop hydronic heating systems. It is a high quality and reliable tubing, though slightly less flexible than PEX-a tubing due to the manufacturing process used for its production.

The oxygen barrier prevents oxygen from the air from penetrating the hydronic heating system and rusting cast iron system components.

It comes in sizes ranging from 3/8" to 1" and works with crimp, clamp, compression, PEX press, and SharkBite PEX connections. ProPEX expansion connections do not work with this or any other PEX-b tubing.

This tubing has a maximum temperature rating of 180 degrees F up to a pressure of 100 psi. It can handle a maximum pressure of 160 psi up to a temperature of 73 degrees F. Rifeng tubing is backed by a 25-year manufacturer's warranty.

Installing piping in homes requires ample knowledge, in order to avoid future plumbing problems. Today, copper pipes have been successfully replaced by piping solutions like PEX, due to its corrosion resistance and flexibility features. Generally there are two different types of plastic pipes –

PEX ( Cross-linked Polyethylene)PB (Polybutylene)

Both of these pipes have many differences that make both of them, exceptional and one of their own kind. PB is basically made of a plastic resin material that was used for plumbing pipes because of its features, like flexibility, cost effectiveness, freeze resistance etc. Unfortunately, people have not accepted these pipes due to its weak features that cause them loss.

PEX is a reliable pipe made from HDPE (High Density Polyethylene). PEX has been used successfully throughout the world for many years. It is the most preferred plumbing option for domestic purposes, though it is not meant for outdoors and could get...

You should look at these kits. They are a very good company from what is said on this site. I borrowed a kit from a friend when I did my bathroom. I used the copper rings. I did not like the cinchers.

And you are probably talking about the expander tool. They run $700. Dont use pex-al-pex and you will not spend alot.

I would go with the Watts.

Which tubing is best to use for hydronic heating applications such as baseboard?
For baseboard and other hydronic heating applications you will want to use either oxygen barrier PEX or PEX-AL-PEX tubing (the aluminum core acts an oxygen barrier). In most applications oxygen barrier PEX (such as ThermaPEX or hePEX) will be used. However, PEX-AL-PEX, because of its ability to hold its shape, is often used. Both of these products are...

PEX stands for Polyethylene cross - linked.

PEX is a strong, flexible and inexpensive alternative to copper pipe. All PEX tubing sold on SupplyHouse.com is backed by at least a 20-year warranty. The flexibility of PEX allows you to run tubing continuously from the distribution point to a fixture without any splicing for elbows or other joints. When you do need to make a connection, it's fast and easy with no soldering required.

The important questions to ask when shopping for PEX tubing are:

1. Will the tubing be used for a plumbing or heating application? This will effect the kind of PEX you get.


2. Will the tubing be installed in a climate that reaches extremely cold temperatures? This will likely effect the grade of the tubing you purchase.

The main difference between plumbing and heating is an Oxygen barrier.

For hydronic heating applications, such as radiant heat and baseboards, you typically need to use PEX tubing that has...

Everything you need to know about plumbing with PEX

PEX plumbing, PEX fittings, PEX tools

PEX (or crosslinked polyethylene) is part of a water supply piping system that has several advantages over metal pipe (copper, iron, lead) or rigid plastic pipe (PVC, CPVC, ABS) systems. It is flexible, resistant to scale and chlorine, doesn't corrode or develop pinholes, is faster to install than metal or rigid plastic, and has fewer connections and fittings.

PEX tubing is made from crosslinked HDPE (high density polyethylene) polymer. The HDPE is melted and continuously extruded into tube. The crosslinking of the HDPE is accomplished in one of three different methods.

PEX plumbing has been in use in Europe since about 1970, and was introduced in the U.S. around 1980. The use of PEX has been increasing ever since, replacing copper pipe in many applications, especially ...

Non-Barrier PEX overview

Flexible, economical and easy to install, non-barrier PEX tubing (a.k.a. PEX plumbing pipe) is a #1 alternative to copper and CPVC rigid piping for residential and commercial potable and non-potable water plumbing applications.

We carry this pipe in red and blue colors for easier distinction between hot and cold water lines and in all major sizes: 1/2", 3/4" and 1". Everhot PEX is NSF certified for potable water applications (including hot chlorinated water) and is lead-free compliant.

Oxygen Barrier PEX overview

External coating of oxygen barrier PEX tubing effectively prevents diffusion of oxygen molecules into the water through walls of the pipe. This feature prevents corrosion of cast iron components in the system (circulator pumps, air purgers, fill valves, boiler heating elements, etc.) and allows using it in hot water hydronic heating applications, including baseboard/radiator heating, fan coils, radiant floor...

More about Non-Barrier Plumbing PEX

Everhot Non-barrier PEX tubing is a cross-linked polyethylene pipe manufactured using silane method of cross-linking. It is a single-layer pipe with smooth inner surface and matte exterior and comes in red and blue colors for easier distinction between hot and cold water lines.

Due to higher flexibility, ease of installation and significantly lower cost, PEX plumbing pipe is increasingly growing in popularity as an alternative to copper pipes.


1/2", 3/4" and 1" PEX pipes sizes are the most common for residential and light commercial installations. The end use or application ultimately determines which size pipe to use, with most common being:

The size of Plumbing PEX is usually determined by the end use, or end application, with most common being:
