What are Pex Bend Supports?

Pex bend supports are specially designed fittings that help maintain the proper bend radius for PEX tubing. PEX, or cross-linked polyethylene, is a popular choice in modern plumbing because of its flexibility and resistance to corrosion. However, to ensure the longevity and reliable performance of your PEX system, it's essential to use bend supports appropriately.

Why Use Pex Bend Supports?

  1. Maintaining the Bend Radius: One of the primary reasons to use Pex bend supports for Pex tubing is to maintain the correct bend radius. Bending tubing excessively can cause kinks or weak spots, leading to leaks or bursts in the piping.

  2. Preventing Wear and Tear: Over time, unsupported PEX can experience wear from friction and movement. Bend supports help minimize this by providing a stable base that reduces stress on the tubing.

  3. Simplifying Installation: Using bend supports can simplify the installation process by providing a clear guide on how to position and secure your tubing, ensuring a tidy and professional finish.

How to Choose the Right Pex Bend Supports

Selecting the appropriate PEX bend supports requires paying attention to a few key details:

  • Size Compatibility: Ensure that the supports are compatible with the diameter of the PEX tubing you are using. This information is usually available on the packaging or from your supplier.

  • Material Quality: Look for high-quality materials that can withstand the conditions of your plumbing system, whether it's for hot or cold water supplies.

Step-by-Step Guide to Using Pex Bend Supports

  1. Gather Your Materials: Before starting, gather your PEX tubing, bend supports, and any necessary tools (like a pipe cutter and fittings).

  2. Plan Your Layout: Consider the layout of your plumbing system. This will help you determine where to position the bend supports to maintain the proper bend radius.

  3. Install the Bend Supports: Securely attach the bend supports to the framing or wall studs using screws or brackets. Make sure they are evenly spaced based on the manufacturer's guidelines—typically every 32 inches for horizontal runs.

  4. Insert the PEX Tubing: Carefully bend the PEX tubing, ensuring you do not exceed the minimum bend radius. Insert the tubing into the bend supports, ensuring it sits comfortably within each support.

  5. Check for Stability: After installation, check the tubing’s stability. Make sure it is securely held in place without excessive movement.

  6. Test the System: Once everything is installed, turn on the water supply and check for any leaks. Inspect the bends to ensure everything is functioning properly.
