Apollo PEX-B tubing is cross-linked, high density polyethylene and is available for potable water distribution systems in red, white and blue colors for easy identification of hot, cold and main water lines. Apollo PEX can be used in continuously recirculating plumbing systems up to 140°F while maintaining chlorine resistance.
Apollo PEX-B Oxygen Barrier Pipe has been designed to prevent diffusion of oxygen into hydronic radiant heating systems. A layer of polymer is laminated to the outside surface which is highly resistant to the passage of oxygen. Oxygen Barrier PEX pipe is good for hydronic radiant heating, cooling, and snow melting systems using water or water/glycol mix. It may be installed in concrete, gypsum-based lightweight concrete, sand, asphalt, in or under wood flooring, or behind wallboard or plaster. Oxygen Barrier PEX pipe may also be used as transfer lines for baseboard heating systems with a maximum operating temperature of 200° F @ 100 psi.
