What is an ASTM F1960 fitting?from plumbermag.com
ASTM F1960 fittings are, in many cases , preferred over alternate fitting connections. In an F1960 connection, the installer simply uses an expansion tool to expand the PEX-a pipe and PEX-reinforcing ring before inserting a fitting. As the ring and pipe shrink back down to their original size, it creates a strong, durable connection that holds tight with up to 1,500 psi of radial force. A 1-inch F1960 engineered polymer (EP) fitting has a 67 percent greater flow rate, at 8 feet per second, than a F2159 plastic fitting and 22 percent greater flow rate than an F1807 brass fitting.

What does SDR mean on a pipe?
This has largely to do with potable water certifications. If a SDR is spotted on the tubing it stands for Standard Dimension Ratio, which corresponds to a method of rating pressure piping. The number following the letters SDR lets you know that the ratio outside diameter to the wall thickness is that many times to 1. A low SDR ratio means that the pipe wall is thick compared to the pipe diameter, and a high one means the pipe is thin. If a pipe has a high SDR, then it has a low pressure rating and vice-versa.
What is the chlorine resistance of PEX tubing?
The next sets of numbers specify the tubing material’s designation code which corresponds to the chlorine resistance (1-5), UV resistance (1-2), 3rd and 4th digits are for hydrostatic design stress in which the numbers vary. For example PEX-AL-PEX has a 4535, meaning its chlorine resistance is 4, UV resistance is a 5, and its Hydrostatic design stress is at 35, which is almost 6 times as much as regular non barrier PEX pipe. Compared to Oxygen barrier or non barrier PEX pipe which has a 5006. This states that the chlorine resistance is at the highest it can be, while the pipe offers no UV resistance and a hydrostatic design stress of 6. All PEX is designed to be used in closed areas under insulation or protection from UV rays. Even when PEX is being transported it is crucial to be kept out of direct sunlight, to prevent damage to the structure. Especially on oxygen barrier, which will have its barrier damaged by the UV rays rendering it useless in its appliance.

Which PEX is the most flexible?
Each method has it's benefits and it's detractions such as; PEX-a is marketed as the most flexible PEX available but this flexibility comes at a loss of chlorine resistance and lower burst pressures. PEX-b has the highest chorine resistance and burst pressures but at a loss of flexibility. PEX-c proponents cite it's clean composition but it does stand out as being more durable or having high chlorine resistance.
How much less is 5/8 in tubing?
If we install our tubing on minimum spacing we will have 20% less 5/8 in. tubing installed than 1/2 in. tubing. But if we look at the surface area of tubing, 5/8 in tubing only has 10% more surface area than 1/2 in. tubing ( .75 X Π = 2.355 in. / .625 X Π = 2.12 ). So you would be at a NET loss of surface area or heat transfer when using a larger diameter pipe when installing at minimum tubing spacings in a radiant floor install.

It will also make for easier routing around built-ins like cabinets and doorways.
Does large diameter tubing help?
So if you need more flow or more pressure, yes a large diameter tubing will help. However, if our use is for heat transfer we have more to consider.
Is HPDE crosslinked?
As the HPDE is cross-linked the manufacturer has to either add "free radicals", or create the siloxane bridge. The manufacturer adds enough "free radicals" such that when they are used up the tubing should reach the desired cross-linked level, or as in the PEX-b method the cross-linking takes place for some time after the tubing has left the extruder. It is almost impossible to get a completely cross-linked tubing. Also the tubing becomes more brittle as cross-linking increases.
Is HDPE a good material for drinking water bottles?
Cross-linking is the stabilizing of the High Density Polyethylene (HDPE) polymer into a material that will not break down. HDPE is clean and cheap and it can also be recycled, that is why it is such a good material for drinking water bottles. However, it breaks down pretty quickly and is not very good as a building material. Cross-linking the HDPE will allow it to handle higher temperatures, give it more chemical resistance and inhibit cracking. So higher Cross-linking is better right? Not so much.
