3/4" PEX Tubing with Oxygen Barrier can be used for the following heating applications:


1. Structural Concrete Slabs (Rebar or wire mesh reinforced, 4-6" thick). Slab-On-Grade Systems (larger garages, warehouses and other storage and commercial facilities). 3/4" PEX Tubing is secured on top of the reinforcement with wire ties, zip ties or clips.


2. Snow Melt Systems (reinforced structural slabs). Similar to radiant heated slabs, but does not require insulation and requires a proper drainage system.


3. Copper tube finned baseboard radiators, cast iron and aluminum radiators.


4. Fan coil units and water to air heat exchnagers.



Everhot Oxygen Barrier PEX Tubing can be installed using either Crimp type connection system (Crimp Tool, Crimp-style PEX Fittings and Copper Crimp Rings) or Clamp/Cinch type connection system (Clamp Tool, Crimp-style PEX Fittings and Stainless Steel Clamps). Also compatible with Push-Fit connection system (such as SharkBite), Viega Press type system and Compression type PEX fittings.


This product is a replacement for:

3/4" PEX Tubing with Oxygen Barrier is the most popular size for all snow melt projects. According to RPA Standard Guidelines, 500ft is the recommended circuit length for the 3/4" Oxygen Barrier PEX Tubing, when used for radiant floor heating applications. For snow melt applications, 300ft length is considered more appropriate.

By Izzy (from PA) on 4/25/2011
I have used 600' of this pipe for a base board heating system in my basement. Pipe is a little ridged but so are almost all 3/4" PEX pipes. Price is great.

How much expanson per foot with hot water passing thru it? Are expanson loops needed?
Read 1 answer
The expansion ratio depends on the temperature rise (delta T) in the system. Approximate formula is as follows:
Total expansion in inches = (delta T) * (PEX pipe length) * 0.001

A 100ft loop of 3/4" oxygen barrier PEX at 70F temperature rise will expand 100*70*0.001 = 7", or about 0.006" per ft.

Expansion loop is unnecessary as long as PEX is installed with a sufficient slack to allow the normal expansion and contraction to occur.
If making an expansion loop is necessary, it should be done in a manner to avoid the trapping of air.
