What is the proper method for cutting LFMC to prevent leaks?

The proper method for cutting Liquidtight Flexible Metal Conduit (LFMC) involves ensuring that the integrity of the conduit is maintained to prevent leaks. Twisting and breaking the PVC jacketing allows for a clean separation without compromising the seal necessary to keep moisture and contaminants out. By twisting, you create a break that aligns with the conduit design, which is specifically engineered to facilitate a tight fit and prevent leakage.

Using a straight cut across may result in jagged edges or an uneven surface, which can create gaps where moisture might enter. Sanding the edges might help smooth out those cuts, but it doesn't effectively address the issue of seal integrity. Making multiple small cuts also risks distortion of the conduit, which can lead to poor fitting and potential leaks. Therefore, the method of twisting and breaking provides the best outcome for maintaining a reliable, leak-proof connection in LFMC installations.
