Bard part number 5452-015 is a red silicone tubing segment specified at 0.196 inch inside diameter by 0.360 inch square outside dimension, commonly used in Bard wall mounted HVAC equipment for routing condensate, pressure reference, or low pressure drain and vent connections where heat and moisture resistance matter. When a tube hardens, cracks, or collapses, it can lead to drainage issues and nuisance service calls, so replacing it with the correct Bard OEM size helps restore proper flow and reliable operation. Match the tubing size to your existing line and connection points, confirm the cut length required for your specific unit, and install with proper routing to avoid kinks or low spots that can trap water.
* Orders less than $50 may incure a minimum order fee.
