Oatey 500K Keeney J-bend Sink Trap 1-1/2 or 1-1/4 Inch

Product Description

The OATEY 500K is a white polypropylene J-bend sink trap designed for bathroom sink drain installations. It forms the curved under-sink section of a tubular drainage assembly, creating a water seal that blocks sewer gases from migrating back into the living space. The trap fits both 1-1/2 inch and 1-1/4 inch drain line configurations and includes a reducer washer to accommodate either size without a separate trip to the supply house. Nuts and heavy-duty washers are included for a leak-resistant connection straight out of the box. Plumbers and drain service techs install this as a direct replacement or new-installation trap body in residential bathroom vanity drain systems.

This J-bend is intended for residential bathroom sink applications where the drain line runs at 1-1/2 inch or 1-1/4 inch nominal size. The polypropylene construction resists common drain chemicals and light corrosion. It is a component of the Keeney tubular drainage line, which covers under-sink drainage assemblies for lavatory and vanity sink configurations in residential settings. The included hardware allows the installer to complete the trap connection without sourcing additional fittings.

Installation Notes

Installation is typically performed by a licensed plumber or experienced drain technician. Shut off the water supply and place a bucket under the existing trap before removal to capture residual water. Hand-tighten slip-joint nuts first to align the trap body, then snug with slip-joint pliers — avoid over-tightening, which can crack polypropylene fittings. Verify the trap arm slope and trap seal depth comply with applicable local plumbing code requirements, which generally reference the IPC or UPC.
