Hello Don, You can put antifreeze in PEX-AL-PEX or Oxygen Barrier. A 50/50 Mixture is a good place to start.
Unfortunately, sharkbite fittings our made for CTS size tubing including copper, cpvc, and regular pex.
This is not regular pex. This is Pex-Al-Pex that features an aluminum barrier in between pex layers. The aluminum acts as an oxygen barrier. For radiant heating you would want to use oxygen barrier tubing on an open system.
This item is made in China
Ultra-Fin plates function most effectively with non-friction PEX (such as Uponor, Viega, Mr. PEX, and Rehau oxygen-barrier tubing), in addition to any kind of PEX-Aluminum-PEX. Rifeng, HeatLink, and Bow PEX have been known to cause noise in Ultra-Fin applications.
Viega PexPress fittings and tools are only compatible with standard pex, and FostaPex. They are not compatible with Rifeng or other brand Pex-al-Pex.
1/2" and 5/8" are the most popular sizes. The thickness is affected by how much concrete is still over the pipes and therefore not compromising the structural stability of the floor. 1/2" PEX in 2" gypcrete works exceptionally well on a well reinforced wood sub-floor. The 25 yr warranty is just that = a warranty plan. There are PEX tubes out there with 50 yr warranties too. No one knows how long PEX tube will actually last but a well installed loop should easily exceed either of those 2 warranties ..

Rifeng PEX-AL-PEX is rated to 200 psi at 73.4°F and to 125 psi at 180°F.
Typically 100psi at 180F 160psi at 74F Vivek Bhatnagar <http://www.ampericon.com> http://www.ampericon.com
I'm sure you can, but a more efficient way would be with the use of radiant panels. I installed this pex in panels sitting atop a slab (in Maine) and it works fantastic.
Mark The pex/al/pex pipe is quite at home under a slab, just keep the boiler water temperature under 200 degrees F Jim

Better to use 1/2" or 5/8" spaced no more than 9"-12" apart. Pex should be installed closer to the bottom of the slab - 1" standoff or cheap broken pavers can be used to raise the supporting mesh. Lastly - and most importantly .. remember to always insulate the entire concrete slab from below. Better to use rigid foam instead of bubble foil insulation. Use as much thickness of foam as your budget allows - at least 1.5". Also good idea to insulate where the slab meets the concrete wall ..
