TUBING
A Slinky® is suspended on elastic threads around
itself. There is no reinforcement along its length.
Thus making it remarkably flexible and free to move.
The shape remains round. It never kinks, although
the bending radius is minimal.
Similarly, PEX molecular chains extend around the
tubing like the Slinky® string circles around itself.
This makes MrPEX® Tubing extremely flexible and
less likely to kink. The molecular chain is aligned to
resist stress around its perimeter. It is unusually
strong, resisting inside pressure.
The molecular orientation is achieved during
extrusion in a very unique process. Crosslinking
occurs simultaneously with the orientation. Peroxide
crosslinking guarantees optimal tubing properties.
Oxygen Diffusion
MrPEX® Barrier PEX
Tubing has an Oxygen
Diffusion Barrier which
meets the stringent
requirements of
the European DIN
4726 standard. This
standard restricts
the amount of oxygen that is allowed to permeate
the pipe and affect corrodible cast iron or steel
components within the system. The standard
restricts permeation to less than or equal to 0.10 g/
(m3 d). This is considered to be a safe level.
MrPEX PEXa TUBING WITH OXYGEN BARRIER
MrPEX® Barrier PEX tubing is Cross-Linked Polyethylene (PEX-a) manufactured in accordance with ASTM F876.
Tubing is listed to ASTM F 876/877 (CSA B137.5) and ICC-PMG 1053, and also certified by NSF (NSF-rfh).
MrPEX® Barrier PEX tubing is rated by the Hydrostatic Stress Board of PPI (Plastics Pipe Institute) at: 160 psi
at 73.4°F; 100 psi at 180°F; 80 psi at 200°F. MrPEX® Barrier PEX tubing has an EVOH oxygen barrier that meet
DIN 4726. Tubing sizes 3/8" through 3/4" also has a thin coating of PE on top of the barrier in order to reduce
noise when installed in joist applications and Aluminum heat transfer plates.
