will this brand of pex burst if water is left in the line and freezes

NO it will not. The fittings will crack if they freek. I work on mobile homes and we ONLY use Pex or Sharkbite Pex tube. I have seen the entire 100 feet freeze and it just swels up a tiny bit. Any fitting that freezes though will crack and burst or leak. Do all home run lines and put a heat tape on it if your woried it may get exposure to winter freezing temps. I have done over 60 homes with this and always get this question.

This is not PEX-A (more often referred to as AquaPEX). This is PEX-B, the most common variation of the three types available. AquaPEX has some benefits, such as less coil memory so that it is easier to work with as well as more resistance to bursting if water freezes in the tubing. It is not better quality, it is just manufactured differently and the letter signifies what method of installation can be used. You only need to use AquaPEX if you are using the expansion method which requires the PEX to expand to accept the fittings. It then resumes its shape around the fitting with the help of special expansion sleeves. With PEX-B, the crimp method is used. You could use AquaPEX with the crimp method, but you could not use PEX-B with the expansion method since it is not designed to expand to the tolerances necessary. AquaPEX is also 40% more expensive and not readily available everywhere. You generally need to buy this type at a plumbing supply house.

Does this tubbing works with pex expansion tool?

NO that tool can only be used on pex - A

What is the i.d. of this tube?

The diagram clearly shows that this tubing is 1/2 in. O.D. and is mated to the Sharkbite 1/2 inch ball valve. Why do you state that it's 1/2 in. I.D.?

Good stuff to work with

This is great stuff at a good price. Be careful if you are looking for the oxygen shield tubing because this is not it. No complaints here

Using for sink and toilets

I am using this for my bathroom sinks and toilets. It works great. As long as the pressure is above about 40psi (I am on well and the pump gets as low as 20 psi before it kicks in). I had to get the 3/8" CTS -> 1/2" FIP and 1/2"MIP x3/8" supply stops. This is attached to a Viega Manibloc and works great. Hot water to the sink in about 1-2 secs/ft of tube.

Perfect

Easy to use, cuts easily with any PVC cutter. Home Depot sells SharkBite 3/8 crimp rings and barbed fittings which worked well with this product. I wouldn't use this sized tubing as the main water feed to any room, I used it to run individual feeds to each item (toilet, dishwasher, outdoor faucet) from a manifold. 100 Feet doesn't go far when you are running individual lines to each use point... I'll be buying another roll soon.

The collor designates the feeder line from the water company line to my RO system.

I used this red tubing to feed water from the line feeding the house to supply the 200 gallon a day RO system in the house. AZ water here in the Huachuca mountains is so hard it'll almost knock the bottom of the glass out if you turn it on too high. Blue tubing is used to feed from the RO system to the outlets.
