Four flexible silicone sealing ribs form a one-way valve. High-volume flows pass through under gravity. The GD6 handles over 550 L/min without restriction.
When flow stops, the ribs close to create a continuous mechanical seal that blocks sewer gas, odors, and pests from entering the occupied space above.
The same one-way valve principle that works at 1.25" scales to 6" with proportionally increased flow capacity.
The GD6 is the largest waterless trap seal in the product line. Independently tested and certified.
