PEX Plumbing Tubing (Non-Barrier)
Everhot PEX Plumbing Tubing is non-barrier PEX-B tubing. It is manufactured to ASTM F876/F877/F2023 standards, certified for potable water applications and used for residential or light commercial potable water plumbing systems. Available in color coded coils for easy distinction between hot and cold water lines. Compatible with crimp, clamp, press and SharkBite connection systems.
The size of PEX Pipe is usually determined by the end use, or end application, with most common being:
1/2" PEX plumbing tubing is the most common of all sizes and is typically used in conjunction with PEX manifolds to carry hot or cold water from the manifold to plumbing fixtures. 1/2" PEX is also the most cost-effective and one of the most flexible tubing sizes.
3/4" PEX pipe is generally used for main water lines in small to mid size residences and usually carries the supply of water from the water heater to the PEX manifold. Due to a larger ID than 1/2" size, it is sometimes used for plumbing fixtures that require greater than normal amount of flow, such as bath tubs, jacuzzi and shower jets.
1" PEX pipe is typically used for water mains in medium to larger size residential homes.
3/8" PEX pipe can be used for plumbing fixtures with normal or less than normal water flow requirements.
All sizes of PEX plumbing tubing may sometimes be used for radiant heating or hydronic heating applications, such as open loop systems, if the system is designed with all non-corrosive (non cast iron) components.

Re-plumbing: Replacing Brass Pipes with PEX Tubing
Q: I'm looking for PEX pipe. Is is the same as PEX tubing?
A: Yes, these two mean the same, although the name "tubing" is more suitable, since PEX is flexible and rigid pipes are not.
Q: Can Non-Barrier PEX pipe be used for radiant floor heating applications?
A: Only given the conditions that all of the components of the system are all rust resistant. Such installations are typical for open loop domestic/radiant systems, where the same hot water is used for both hot water plumbing and hydronic or radiant heating purposes. Since such systems will almost always have a supply of fresh water, enriched with oxygen, installing oxygen barrier PEX pipe makes no sense.
