PerformaFlex Outer Casing

Not every outer casing is the same.  We have ours made specifically for us at 160 gpf of high density plastic.  It meets or exceeds ASTM 405 and other specifications.  If you are considering using another brand, please take a moment to ask to see their spec sheet.  And while you are at it, why not ask where their insulation and pex is made. Don't be surprised to hear China. Ours is made in the USA.

PerformaFlex Insulated Pex Pipes

PerformaFlex  is a premium grade insulated pex system. Available in 3 different versions. The insulation is closed cell R-Foam™ with outer reflective radiant barrier. This high quality made in USA R-Foam™ has 40% better thermal properties than standard polyethylene or polypropylene (microfoil) foam.

PerformaFlex is not a bubble wrap layered product.

Tests were conducted by a third party and under normal outdoor wood boiler conditions running at 5 GPM, with buried pipe and under a 63.5K BTU load. While we believe these results to be accurate and the installation to be typical, they are not guaranteed nor warrantied, and individual results may vary.

* Free Shipping applies to orders shipped to locations east of the Dakota's. For locations west of the Dakota's, shipping usually runs from $0 to $200 depending on location. Please call for a freight quote. 100' minimum for free freight Call or email for pricing on shorter lengths.

 
Pex Tubing

Pex tubing is manufactured to SDR9 standards which is the same outside diameter as copper pipe but has a wall thickness 1/9th the diameter. You need to be real careful when you see something advertised like "true 1 inch" or "Not 1 inch OD like others" because 99% of the time they are selling metric pex and you may have a hard time finding fittings(especially when they don't tell you the real size) and you have no option for crimp fittings.  Also, if you ever have a problem and need to repair it you probably won't be able to find fittings locally.

NB= Non Oxygen Barrier Pex  OB= Oxygen Barrier Pex

OB usually isn't required unless you are running a pressurized system with no chemicals. It never hurts to use OB pex on an open system (open system has overflow tube at boiler) but is usually just a waste of money and doesn't make any difference.

NOTE:
* Non Barrier pex tubing is either Red or Blue throughout the pipe (inside and outside ).
* Oxygen Barrier pex tubing is either Red or Blue on the exterior but the inside will appear almost white.
(Example: the 3/4" Pex above is Non Barrier and the 1" Pex is Oxygen Barrier ( inside almost white ). )
* All Pex tubing is pressure rated at 80 psi @ 200 degrees and 100 psi @ 180 degrees.
* Our pex is complies with ASTM F876/F877 standards with ROHS certification

Pex-Al-Pex Tubing

Pex-al-pex is sold as inside diameter instead of copper tube size. It has a few advantages over normal pex. It doesn't expand in length so if you have an installation that can not allow for expansion when the pex gets hot you may want to consider it. Also the sizes fall between pex so it is also a good alternative if you need something a little bigger than 1" pex.

PEX-AL-PEX is made with an exterior layer of PEX then adhesive followed by a layer of aluminum, another layer of adhesive and finally a layer of PEX. The aluminum acts as an oxygen barrier so all PAP tubing is considered OB.
