PEX tubing technical specifications and general installation practices can be found on how to bend pipe.

It is easy to use PEX tubing for plumbing projects.PEX is easy to cut and join and requires few special tools.PEX tubing is easy to bend.There are three ways to help PEX tubing make turns.

An elbow is a fitting used to create a 90-degree bend in PEX pipes.An elbow does not bend the PEX tubing.Two straight sections of PEX tubing are connected.

Push-fit 90-degree elbows allow you to push the PEX tubes straight into the elbow with no other tools involved.The crimp-fit joint system is an alternative.The brass fitting is pushed over by the PEX tubes.The ends of the PEX tubing are crimped with brass rings.

PEX bend supports are made of metal or plastic and can be used for a 90-degree turn.The supports have nails that allow you to secure them.

The PEX is usually brought to its allowable 90-degree turn without folding or crimping.The turn radii are determined by the diameter of the PEX pipe.The tightest radius is usually five inches for 1/2-inch PEX pipe.

The plastic clips are attached to the nails.The top of the PEX pipe is nailed with the clamps.They allow for a wide range of turns, from tight turns to wide, sweeping turns.

Tubes should be square-ended and free of plastic burrs.Use a cloth to clean the ends.

An indelible marker can be used to mark the stop or insert point on the PEX tubes.Different brands may have different depths.You can use the pipe insert depth chart for your brand.You should mark both tubes.

Hold the elbow in one hand and the tube in the other.The tube should be pushed into the elbow.You have to push in a single motion.The tube can't be pulled out by hand because of its internal barbs.You will have to use a special tool.

PEX tubing can be crimped if it is bent wrong.If you want to warm up the PEX tubing, you can either use a heat-gun at the lowest temperature setting or sit it in a warm room.

Push the PEX tubing into the bend support.It's important to maintain the pliability of the tubing.

Slowly bend the PEX tubing until it matches the curve of the bend support.You will fold the tubing if you bend too quickly.

Push the tubing into the support until it clicks into place.

The nailed PEX must be wood.The wood must be strong enough to prevent the nails from pulling out.PEX puts stress on the clamps when it is initially bent.
