200 PSISharkBite fittings are certified to 200 PSI and 200°F (93°C).
How much will PEX expand?
1-2.5” per 100 feetSince PEX will expand and contract 1-2.5” per 100 feet of length with every 10°F change in water temp, it should not be pulled tight during the installation. In case of 60F temperature rise, 100 feet may elongate as much as 15”.

PEX A, B or C - Understanding the Differences :: Apollo Valves
If you've ever shopped for PEX tube you probably know there are three main types. These are PEX A, PEX B and PEX C. In hindsight, that's an unfortunate naming scheme, because it makes it sound like these are grades and implies that one is better or worse than the other.

How much pressure can a PEX pipe hold?
A: ASTM F1960 ProPEX fittings hold strong with 1,000 pounds of radial force. PEX-a pipe can withstand a burst pressure of around 800 psi (almost two times the requirement for ASTM F876, the standard specification for PEX tubing).
Which PEX pipe is the most flexible?
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.
Can PEX be used for air lines?
PEX is designed for liquids and shouldn't be used for air lines. The tubing is "likely" ok, but the fittings are not, AFAIK. There is a similar product out there, however, that is designed for air.
Can you use PEX pipe for compressed air?
Q: Can I use PEX pipe for compressed air applications? A: No, PEX pipe is not intended for compressed air applications. I had pex in my last shop for six or seven years.
What size PEX should I use?
PEX tubes range in diameter from 3/8-inch to 1-inch for residential applications. For adequate water flow, it's a good idea to install 1/2-inch or 3/4-inch PEX for your main lines.
Why is PEX plumbing bad?
Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation. Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also.
Can Blue PEX be used 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. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
Can you put PEX in concrete?
Yes, PEX pipe can be installed under a concrete slab. PEX pipe can also be encased within a slab, which is commonly used for radiant floor heating. In cases where PEX pipe penetrates a concrete slab, it must be protected with a nonmetallic sleeve at the penetration point.
What kind of pipe to use for compressed air?
Black pipe is the most commonly used pipe recommended for compressed air systems.
Can sharkbite fittings be used for compressed air?
Can I use SharkBite fittings for anything other than potable water and radiant heating (e.g, air, gas, oil, etc.) applications? No, fittings are only certified for potable water and radiant heating installations.
Why is PEX banned in California?
Uponor Wirsbo said its PEX pipe was introduced in California in 1990 and that the product helps solve problems in areas with aggressive soil conditions that copper pipe cannot solve.
How much pressure can a PEX pipe hold?
A: ASTM F1960 ProPEX fittings hold strong with 1,000 pounds of radial force. PEX-a pipe can withstand a burst pressure of around 800 psi (almost two times the requirement for ASTM F876, the standard specification for PEX tubing).
What is the maximum pressure for PEX tubing?
As the temperature increases the max operating pressure drops. Most PEX tubing will be rated for: 160 psi at 73°F. 100 psi at 180°F.
Can you use PEX pipe in compressed air?
A: No, PEX pipe is not intended for compressed air applications. I had pex in my last shop for six or seven years. It worked fine.
Why should PEX be secured?
Since PEX expands and contracts with temperature changes, it should be secured so as to provide sufficient space for expansion to occur.
What is the SDR 9 for PEX?
PEX made to US standards must comply with a SDR-9 (Standard Dimension Ratio), which is the ratio of OD (Outside Diameter) to pipe wall thickness (9:1). Exceptions are nominal sizes 1/2" and below.
What is PEX overbending?
Over-bending the PEX pipe, deforms its’ round shape, restricts flow and over-stresses the pipe.
How much pressure is needed to pour concrete?
For concrete slabs, pressure is maintained at 30 psi during the pour and is monitored to assure integrity of the system.
Is PEX tubing universal?
Since all PEX tubing used in the US is manufactured to the same ASTM and dimensional (SDR) standards, these specifications are universal. Manufacturing tolerances and other details can be found in manufacturers’ manuals.
