How to Bend PEX Tubing
PEX Tubing (

PEX pipe is a semi-flexible water-supply pipe that is useful for many applications. From general plumbing to radiant heat floors, PEX is a go-anywhere plumbing solution. Bending PEX tubing is a snap, but you have to remember to strap the tubing into place so the bends will stay where they need to. You can also use PEX hangers to accomplish this.

  1. 1

    Run a length of PEX tubing along your intended path. Allow sufficient slack in the tubing to create a 12-inch S-curve or a 12-inch diameter loop in the tubing.

  2. 2

    Place a PEX strap or a PEX hanger over the PEX tubing while allowing the tubing to move (because the tubing will expand and contract depending on temperature variations). Then create either an S-curve or a loop in the tubing with the slack that was left in the tubing and hold the S-curve or loop in place with another PEX strap or PEX hanger.

  3. 3

    Continue running the tubing to its intended termination points and install fittings as necessary.
