The UEL M10E Solvent Weld Waste Pipe Straight Coupler is a commercial-grade plumbing socket engineered to connect two straight runs of domestic or commercial wastewater piping. Featuring a standard 40mm (1.5 inch) outer diameter with dual straight female sockets, this inline connector is injection-molded from a high-impact ABS/PVC polymer blend built to handle continuous hot-water discharges and harsh household chemicals. Formulated specifically for solvent welding, it establishes a permanent, leak-proof molecular fusion when treated with standard solvent cement. Its smooth internal profile maximizes fluid dynamics, drastically reducing flow resistance to prevent grease, hair, and structural debris from accumulating in hidden behind-wall or under-sink installation lines.
