Jay R Smith BAR3 Drain Odor Protector Trap Seal

Product Description

The JAY R SMITH BAR3 is a rubber drain odor protector designed to prevent sewer gases from entering a building through floor drains and other low-use drain points. Commonly called a trap seal or stink stopper, it works by creating a flexible barrier that blocks gas migration when a trap runs dry. This type of device is installed in drains that see infrequent use, where standing water in a P-trap evaporates over time and leaves the drain path open to sewer odors. Installation is handled by licensed plumbers during new construction, renovation, or as a retrofit solution on existing drain bodies.

The BAR3 is suited for floor drains in commercial kitchens, mechanical rooms, restrooms, laundry areas, and other spaces where drain traps are prone to drying out. Its rubber construction allows the seal to flex open under normal drainage flow and return to a sealed position once flow stops, maintaining passive odor control without requiring maintenance or water replenishment. It is appropriate for both residential and light commercial plumbing applications.

Key Features

• Rubber construction provides flexible, self-seating seal under normal drain flow
• Passive design requires no power, water feed, or ongoing maintenance
• Prevents sewer gas infiltration when trap water evaporates in low-use drains
• Retrofit-friendly for installation in existing drain bodies
• 4-inch nominal size fits standard floor drain applications

Compatibility

Designed as an OEM-style replacement or retrofit trap seal for 4-inch floor drains in residential and commercial plumbing systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain is clear of debris before inserting the trap seal. The rubber seal should seat fully and evenly in the drain body to ensure a proper gas-blocking fit. Do not use solvents or lubricants that may degrade rubber on the sealing surface.
