How long can oxygen barrier PEX be exposed to sunlight?

Is oxygen barrier PEX necessary?
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 all PEX pipe oxygen barrier?
The “barrier” referred to in PEX tubing is actually an oxygen barrier. This extra layer in your tubing will assure that no oxygen gets into your heating system. Oxygen in your system can be a problem that causes your system components to rust.

What’s the difference between oxygen barrier PEX and regular PEX?
Oxygen Barrier PEX, often abbreviated as O2B or referred to as O2 Barrier, has a coating applied to the outside to prevent oxygen (O2) from entering the system (The O2 molecules are smaller than those of PE.) Oxygen Barrier PEX is used when installing in a closed or pressurized system.
How do you know if PEX tubing has oxygen barrier?
What is oxygen barrier PEX tubing?
More about Oxygen Barrier PEX Tubing. PEX with oxygen barrier offers an effective and low cost solution for protection of ferrous parts in hydronic and radiant heat systems against rusting and corrosion. Another type of radiant heat tubing is PEX-AL-PEX.
What is the difference between barrier PEX and non barrier PEX?
Barrier vs. Non-Barrier PEX. 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.
What is PEX pipe used for?
