John Guest Speedfit Polyethylene Tubing
I’m using three John Guest Speedfit polyethylene tubing products, 3/8” Blue x 500 ft, 1/4” White x 500, and 1/4” Blue x 500 ft. to re-plumb an under-sink RO Water purifier system
I’m using the 1/4” Blue and White tubing . The 3/8” tubing is used for the drain which couples to a short length of 1/4” tubing coming off the RO Water system. I’m also using the 1/4” tubing to supply a water source from the RO system to an Espresso machine which sits on the kitchen counter.
The low-density polyethylene tubing is flexible and durable, and easy to work with. Available in black, white, natural/gray, blue, and red, the multiple colors help identify and organize different water lines (source, drain, faucet, etc.). Connections and coupling is especially easy with John Guest Push-Fit fittings, couplers, and unions. The bulk spools are convenient and cost effective. especially if you’re going to do multiple projects and need longer runs. Installation went smooth, good quality polyethylene tubing, I highly recommend.

1/2 in. x 1000 ft. Red Polyethylene PEX Tubing Oxygen Barrier Radiant Heating Pipe
PEX tubing is ideal for new constructionPEX tubing is ideal for new construction and remodeling projects. It can be used in both residential and commercial areas. It becomes more convenient to a water supply piping system, creating great advantages compared to a metal pipe. It is more flexible, more resistant to scale and chlorine, and it is faster to install than metal or rigid plastic because of its fewer connections and fittings. It is very durable with harsh water conditions. It is suitable for use in most plumbing applications and radiant heating installation methods such as: Thick/Thin concrete slabs Under sub-floor (between joist) with or without heat plates Engineered floor Staple up or staple down Baseboard and radiator Snow melting systems Solar heating applications.See Full Product Description
