Dearborn 701DFBN-1 1-1/4" P-Trap with Deep Flange and Brass Nuts – Tubular Drainage Component

The Dearborn 701DFBN-1 P-Trap is a 1-1/4 inch tubular drainage fitting designed for use in sink installations requiring effective waste line connection and odor containment. Manufactured with a deep flange and equipped with durable brass nuts, this P-trap is built to meet plumbing code requirements while maintaining service integrity in residential and light commercial systems.
