What is oxygen barrier PEX tubing used for?

Used for radiant in-floor and hydronic heating applications. Oxygen barrier helps prevent the corrosion of ferrous metal parts in the heating system.

Do you need 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.

Is PEX and wirsbo the same?

PEX is slang for “Crosslinked Polyethylene”, a popular type of plastic material used for plumbing and heating pipes all over the world. Wirsbo is simply one of many brand names of PEX in the marketplace. Typically, PEX-a is used with cold expansion fittings (F1960) or Uponor / Wirsbo’s brand name Propex fittings.

Can I use oxygen barrier PEX for domestic water?

Most oxygen-barrier PEX does not have the appropriate approval codes for use with potable water and should not be installed in domestic plumbing applications. This layer normally makes the tubing unsafe for potable systems, but this is no longer the case with hePEX tubing.

Can you use PEX AL PEX for drinking water?

PEX-AL-PEX is currently permitted for potable water in the International Plumbing Code. The material is also listed with the Uniform Plumbing Code.

Can PEX be used for heating?

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.

Can you use blue PEX for hot water?

Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water.

Can PEX be buried?

PEX tubing is approved for direct burial outdoors, a practice most often necessary when running a water supply line to a house. Sleeving the buried PEX (in PVC, for example) shields the tubing and can make potential repairs easier. Embedding PEX in sand protects it from any rocks in the soil.

What PEX system is the best?

PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant.

Can you use PEX fittings on wirsbo pipe?

This is a question we receive frequently at pexhouse.com and the short answer is the Wirsbo IS PEX! PEX is slang for “Crosslinked Polyethylene”, a popular type of plastic material used for plumbing and heating pipes all over the world.

What’s the difference between PEX and oxygen barrier?

The standard for the oxygen diffusion barrier is DIN 4726, and must be listed directly on the pipe to ensure its use with such systems. Non-Barrier PEX is used for a whole different assortment of applications. It is commonly used for everyday hot and cold water applications, along with potable water applications as well.

When to use 5 / 8 ” oxygen barrier tubing?

5/8″ oxygen barrier PEX tubing sometimes replaces 1/2″ tubing when project calls for higher heat loads or flow rates. It can also substitute 3/4″ PEX in applications that require more flexibility and less flow (such as smaller snow melt systems). Q: Is Everhot Oxygen Barrier PEX Lead-Free? A: No.

Can you use non-barrier PEX tubing for radiant heating?

Due to its oxygen barrier the tubing can be used for radiant floor heating, hydronic heating, and ice melting applications, where the Non-Barrier tubing would corrode. The standard for the oxygen diffusion barrier is DIN 4726, and must be listed directly on the pipe to ensure its use with such systems.
