One of the advantages to making use of pex bend support vs elbow for plumbing work is that it’s easy to work with.
PEX is affordable, cuts and joins effortlessly and needs only a few particular equipment.
PEX tubing is simple to bend. To assist PEX tube turn it is possible to use one of three options such as 90 degree-degree elbows, clamps, and bend supports.
Contents
PEX 90-Degree Elbow
An elbow is a fitting in pex tubing in the shape of an L which helps create 90 degrees of bend in PEX pipes.
It doesn’t bend PEX tubing by itself. Instead, two straight pieces of bending pex tubing bends connect via a 90 degree, L-shaped connector.
90-degree elbows with push-fit design let you push bending pex tube directly into the elbow with no other equipment needed (you could require an PEX cutter or an PEX removal tool).
A different option is to use the crimp fit joint system. This system uses bending pex tube are placed over an brass fitting. Brass rings are then crimped on the end of PEX tubing using a specific device.
PEX Bend Support
PEX Bend supports can be described as quarter-turn steel or plastic structures that help hold the bending pex tubing to the surface for 90-degree angle.
Certain supports come with nails which enable you to fix it to the substrate beneath.
Bend support usually help bring the PEX up to the tightest possible 90-degree angle without being folded or crimped.
Radii of turn vary based on PEX pipe’s diameter. In the case of 1/2-inch PEX pipe insertion depth chart the most tight bend support radius will be 5 inches pex piping.
PEX Clamps
Pex clamp method are individual clips made of plastic that have attached nails.
They are clamps are fixed to the surface of the PEX pipe insertion depth chart.
They can be used to make a variety of turning angles, from narrow turns that are similar to those made by with rigid pipes or bend supports, to broad sweep turns.

Instructions
How to Bend PEX With a 90-Degree Elbow
- Clean the Tube EndsThe tube ends must be clean, square-ended with no plastic sleeve burrs. Take care to clean the ends using the help of a clean cloth.
- Mark the TubesIf you are using push-fit connectors make use of an indelible marker to identify the stop or insertion location at the PEX tubes that connect the connector. Different fittings may differ in the insertion depths. Check the pipe insert depth chart of the model you have chosen. Make sure you mark both pipes.
- Push the Tube Into One Side of the ElbowPlace the elbow on one hand while holding put the tube into the opposite hand. Pull the tube towards the elbow. The tube must be pulled with a single, steady movement. Due to push-fit connectors’ barbs inside, they can’t be pulled off manually. The only option is to use an instrument that is specifically designed for removal.
Bend PEX With a Bend Support
Warm the PEX Tube
- While PEX tubing is flexible but it may crimp when it’s bent incorrectly. Begin by radiant floor heating the PEX tubing either through letting it rest in a warm area or with a heat gun with the lowest setting.
- Push Into One Side of the Bend SupportThen, push the PEX tubing through one end of the support for bends. Make sure to work quickly in order to keep the flexibility of the tubing.
- Bend the PEX TubingThen slowly stretch slowly the PEX tubing to ensure it aligns with the curvature of the support for bends. If you are bent too fast it will cause you to crimp and bend the tubing.
- Push Into Other Side of the Bend SupportThe tubing’s curve should match the curve of the support bend then push the tubing towards the supporting until it snaps into position.
Bend PEX With Clamps
- Examine the Nailing SurfaceIf you are bent pex tubing using clamps, the surface for nailing is to be made of wood. It must be level and strong enough to keep the nails from slipping out. If pex tubing is bent initially using clamps, it puts tension upon the clamps.
- Mark the Intended CurveUtilizing a pencil, an straight edge straight or the Speed Square Mark the desired shape on PEX tubing. PEX tubing. Most of the time you could draw the angle using two straight lines instead of making the curve. This allows you to identify the angle.
- Nail Down One ClampOn the opposite edge of the curve attach on the other side of the curve, attach a PEX clamps on the board. Make sure to not damage the sleeve of plastic sleeve in the clamp. Place the other pex tube through the clamp.Tip If you’re continuing to use an existing pipe, rather than beginning a new one, then the clamp has to be fixed on top of the pipe.
- Bend the PEX TubeGently gently bend gradually bend PEX tube slowly until it reaches the final place. To avoid stress being pulled out of the first clamp, it is possible to require to secure the end of the tube.
- Nail the Second ClampPlace the second pex clamp on top of that PEX tube. Then nail it in place. Release the clamp onto the tube only after the pex clamp is securely held in position.
FAQ
Do you need bend supports for PEX?
PEX Bend Supports allow 90deg of bendability to PEX tubers, removing the need for the addition of a fitting and reducing leak-points. Bending supports to reduce vibration and noise, too.
What is the difference between bends and elbows?
The main difference is in the diameter.
The lateral curve typically is approximately 2 to 3 times the size of the diameter of the pipe.
The radius of bending can be about 2 times larger than the diameter. The manufacture of elbows is done by producers with restrictions on length, angle and angles.
Is it OK to bend PEX 90 degrees?
Bend supports typically let PEX 90 degree turning with no the need for folding or crimping. Angles of rotation depend on the diameter of PEx pipes. The distance that is the longest in PEX tubes is typically five inches. April 28, 2020.
Do PEX elbows reduce flow?
The CPV pipe restricts the flow to around one percent however PEX pipe will limit the flow by about 1%. PEX pipe can reduce the flow by between 23 percentage to 54% according to the pipe’s fitting. 20 January 2020.
Final
The bottom line is that the bending of installing pex tubing could be an essential element in the process of installation as it can help you maneuver narrow spaces and corners.
There are a variety of methods for bending PEX tubing.
This includes making use of a pipe-bending device, the heat gun or just a set of pliers.
No matter which method you pick It’s essential to do your research and ensure that the bent is straight and evenly in order to prevent kinking and damage to the pex tubing.
Also, in order to cut costs during the installation process, it is essential to prepare ahead, get large quantities, and utilize the pex tubing cutter to make smooth and straight line cuts.
Utilizing these tricks and methods that you’ll learn bend PEX tubing as a professional and finish the plumbing job effectively and efficiently.
