Oatey 738W-1 Sink Trap 1-1/2 Inches 20 Gauge Brass Polished Chrome Washer Joint Npt

Product Description

The Oatey 738W-1 is a 1-1/2 inch nominal sink trap designed for residential and light commercial drain applications. Built from 20 gauge brass with a polished chrome finish, this trap delivers a clean look under exposed vanity and kitchen sink installations. It connects using a washer joint NPT fitting, making installation straightforward for licensed plumbers and experienced DIY professionals alike. The trap is designed to hold a water seal in the drain line, which blocks sewer gases and odors from entering the living space. This is a critical function in any properly installed plumbing drain, waste, and vent system. The 1-1/2 inch nominal size is the standard for bathroom lavatory sinks, making this trap a direct fit for most single-basin vanity drains. The 20 gauge brass construction provides solid wall thickness that resists corrosion and holds up to regular use without cracking or deforming. The polished chrome finish gives it a bright, finished appearance that is suitable for exposed installations under pedestal sinks or open vanities. The washer joint NPT connection style allows for hand-tight assembly with a compression washer seal, which reduces the need for thread sealant tape during installation. This trap is an imported product that meets standard plumbing specifications for drain trap assemblies. HVAC and plumbing professionals will find this trap useful as a reliable, code-compliant replacement part for aging or damaged sink traps. It fits into standard P-trap configurations commonly found in residential bathroom and kitchen plumbing layouts. Stocking this part is a practical choice for plumbing contractors who regularly service bathroom vanity drains and need a dependable chrome brass trap on hand.
