Understanding Liquid Tight PVC Electrical Conduit


Versatility and Application


Liquid tight electrical conduit comes in various wall thicknesses and levels of flexibility. It is commonly used in residential and commercial applications where protecting electrical wiring from moisture and physical damage is essential. This type of conduit is particularly useful in areas prone to water exposure, such as basements, attics, and outdoor installations.


Tools and Preparation


While there are many specialized tools available for cutting non-metallic liquid tight conduit, the following time-trusted method uses common tools you likely already have. For this task, you will need:


- Tape measure or ruler

- Ball of string or cord

- Paper and pencil/pen

- Marking pen

- Light-colored tape

- Hacksaw with a fine cutting blade

- Bench vise or clamping device

- Fine metal file

Step-by-Step Guide to Measuring and Cutting


Step 1: Gather Your Tools


Ensure you have all the necessary tools at hand before you begin. This preparation will make the process smoother and more efficient.


Step 2: Measure Your Conduit Path


Straight Lines


If your conduit path is straight with no bends or obstructions, simply measure the distance between the two points using your tape measure. Record this measurement on your paper.


Corners and Obstructions


For paths that go around corners or obstructions, measure each straight section first and note these measurements. Use a piece of string to measure around corners or over obstructions. Stretch the string along the intended path of the conduit, ensuring it mimics the centerline. Straighten the string and measure its length with your tape measure. Record these measurements accurately.


Step 3: Mark Your Cutting Point


Lay your PVC conduit on a flat surface and use the measurements you recorded to mark where you need to cut. Place a piece of light-colored tape over the cutting area. Measure again to ensure accuracy, then use your marking pen to draw a straight line directly on the tape. This line will guide your cut.


Step 4: Secure the Conduit


Place your conduit in a bench vise or another clamping device to hold it securely. Ensure the section to be cut is accessible and stable. Securing the conduit properly is crucial to achieving a straight and even cut.


Step 5: Cut the Conduit


Using a hacksaw with a fine cutting blade, carefully cut along the line you drew on the tape. Follow the line around the entire circumference of the conduit to ensure a uniform cut. Take your time to maintain control and precision.


Step 6: File the Edges


Once the cut is complete, remove the conduit from the vise. Use a fine metal file to lightly file the cut edges, removing any burrs or rough spots. This step ensures a clean, smooth edge that will fit properly with connectors and other conduit pieces.


Tips for a Successful Cut


Double-Check Measurements


Accurate measurements are the foundation of a successful conduit installation. Double-check your measurements before making any cuts to avoid mistakes and waste.


Use a Sharp Blade


A sharp hacksaw blade will make cleaner cuts and reduce the effort required. If your blade is dull, replace it to ensure optimal performance.


Take Your Time


Rushing through the cutting process can lead to mistakes and uneven cuts. Take your time to follow each step carefully, ensuring precision and safety.




Measuring and cutting non-metallic liquid tight PVC electrical conduit is a straightforward process when you follow the proper steps and use the right tools.
