Tubular products are lightweight, thin-walled drainage fittings and components used to convey wastewater from plumbing fixtures like sinks and lavatories to the drainage system. Tubular products are usually installed in accessible locations, such as under sinks or in cabinets and are typically manufactured from materials like brass, polypropylene, or PVC. Tubular connections allow for easy alignment, adjustment, and disassembly without solvent welding or threading. This allows quick installation and removal for cleaning or repair and makes maintenance more straightforward compared to rigid DWV piping systems.
