MrPEX®-a Barrier Tubing
A Slinky® is suspended on elastic threads around itself. There is no reinforcement along its length. Thus making it free to move and remarkably flexible. 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 Mr. PEX® Tubing extremely flexible and kink-resistant. 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 which is a very unique process. Crosslinking occurs simultaneously with the orientation. Peroxide crosslinking guarantees optimal Tubing properties. See Sample Specification below.
MrPEX® PEX-AL-PEX Tubing
MrPEX® Composite Pipe consists of five layers, inside and outside layers are made of Cross-Linked Polyethylene (PEX) tightly bonded with melt adhesive to the mid-layer of aluminum core which is longitudinally welded in an overlap.
All layers are extruded in one step. The middle layer of aluminum is 100% gas/oxygen tight, giving it advantages of both metal and plastic pipe, but not the disadvantages. The Pipe conforms to ASTM F 1281, is pressure rated by PPI and certified by NSF. Since the thermal elongation and contraction is 9 times less than for PEX, noise generation after installation is virtually eliminated.
Manifolds
A Supply Manifold, marked w. Red Circle and a Return Manifold, marked with Blue Circle, are displayed here. A Basic Manifold without valves is also available (not displayed). Manifolds are sold separately, so user may select his own combination of Supply, Returns, and Basics. The Manifold branches are Eurokonus (EK) 20 – compatible with many fitting makes, including our fittings for both PEX tubing and PEX-AL-PEX Tubing. All Manifold Trunk parts (transitions to Copper, NPT, PEX, PEX-AL-PEX, Blinds, Fill/Drain, etc.) come with an O-ring seal. Branch Blind Caps are available to cap off unused branches (for future hook up). See our Parts Catalogue for further info.
MrPEX® 1.25″ Stainless Steel Manifolds
MrPEX® 1 1/4” Stainless Steel Manifold is made from high quality stainless steel, and is offered in 2 through 10 loops. The manifold is delivered pre-mounted on brackets and comes with thermometer wells on the supply and return body (ready for an optional thermometer), and end caps with fill/drain valves.
Fittings & Accessories
MrPEX® can supply you with virtually any other radiant floor component needed. Mixing valves, controls, heat transfer plates, fasteners, accessories, etc.
