Description
This FostaPEX Prep Tool is required to ensure the tubing is prepared for secure PEX Press connections.
FostaPEX tubing adds aluminum and PE outer layers to the tubing to provide form stability and an oxygen barrier. FostaPEX can be bent and will hold its new shape - excellent for exposed runs in basements and baseboard connections. For use with the Viega press fittings only.

Product Q&A
9 QuestionsQ: Hello, If I use the FostaPEX prep tool to strip the outer layers, will that allow me to use standard barbed fittings and crimp/clamp systems with the remaining exposed inner tube? From what I can tell, the innermost tube of FostaPex looks like standard PEX.. Thanks, James

Verified Reply- PexSupply StaffWe would only recommend using PEX Press fittings with FostaPEX tubing.
don't do it. don't use ANY pex fittings other than Viega Press with the Fostapex. They are the best in all aspects, and will NOT leak. I use FostaPex for baseboard heat runs, and for compressed air in my shop. Viega fittings are like mini-hydraulic fittings, and are the very best. Yes, make sure you use the prep tool on the fostapex.
Yes. That's the idea. From their website: "Viega FostaPEX is the only product on the market with a fully dimensional PEX tubing wall, allowing it to be used with the standard Viega PEX Press fitting system."
Q: I am a DIY newbie homeowner. Can I use a Sharkbite coupler to go from 1/2" Frostapex to a more standard 1/2 PEX pipe like they sell in hardware stores?

Verified Reply- PexSupply StaffFostaPEX only works with PEX press fittings. You would not be able to use a SharkBite fitting with it.
Q: Which hangers should I use to mount 3/4" FostaPEX onto and through joists? 3/4" Fostapex has an OD of .875", too small for 1" and too big for 3/4"
Asked by Mal 14 years ago

Verified Reply- PexSupply StaffAny hangers designed for use with standard 3/4" PEX tubing (i.e. PEX without an aluminum layer) will work with 3/4" FostaPEX. Like 3/4" FostaPEX, 3/4" PEX tubing has a 0.875" outside diameter.
Standard copper tubing used for water supply has an OD of 0.875, or 7/8", the same size as FostaPEX. See, it's nice that they thought about this ahead of time. In the building trades, it seems that nothing is the size it says it is. 2x4s are 1.5x3.5, 1/2" iron pipe is bigger than 1/2" even on the inside. The same is true of copper tubing. On the other hand, air conditioning tubing is measured on the OD. So 1/2" A/C tubing is the same as 3/8 water tubing.
I just recently installed the ¾” FostaPex in my addition for all my heating lines and I used a combination of the multi-sized Tube Talon and the ¾” j-hooks. I mostly used the Talon’s as they were easier to install in my application, however both have a “snap” tight fit that works very well. Fair warning though, the Talon nails are ribbed, so when they are in, they’re in! http://www.pexsupply.com/PEX-Tube-Talons-198000 http://www.pexsupply.com/J-Hooks-15022000

Q: What is the btu ratings for 3/4 inch fostapex
Asked by tipper 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe tubing itself does not have a BTU rating. In a radiant heat system, the amount of BTU's you will get through the tubing depends on the boiler, the delta T, and the sizing of the tubing and circulators.
Q: Is this product rated for potable use? What is the minimum bending radius? What is the exact outside dimension of this tube?
