Oatey DB705GBN-1 Choked Throat P-trap 1-1/4 X 1-1/2 Inches Brass Ground Joint

Product Description

The Oatey DB705GBN-1 is a choked throat P-trap designed for drain line installations in residential and light commercial plumbing systems. This brass P-trap features a nominal size of 1-1/4 x 1-1/2 inches, making it a go-to choice for connecting sink drains to branch drain lines where a size transition is needed. Plumbers and pipefitters rely on P-traps like this one to maintain a water seal in the drain line, which blocks sewer gases from entering living and working spaces. The choked throat design refers to the narrowed inlet of the trap, which is sized at 1-1/4 inches to match standard sink tailpiece dimensions while transitioning to a 1-1/2 inch outlet for connection to the branch drain. This configuration is common in bathroom vanity and lavatory sink installations. The ground joint connection style allows for a secure, leak-resistant assembly without the need for soldering or threading. Ground joint fittings use a compression-style slip connection that can be tightened by hand and then snugged with a wrench, making installation and future service straightforward. Constructed from 17-gauge brass, this P-trap delivers solid durability in wet environments where plastic alternatives may not meet code or professional standards. Brass resists corrosion and holds up well to repeated disassembly, which is valuable for service plumbers who need to clean or inspect traps over time. This is an import product, offering reliable performance at a practical price point for contractors and service professionals working on high-volume jobs or budget-conscious projects.

• Ground joint connection provides a reliable, tool-assisted slip fit without soldering or threading
