Wax-Free Toilet Gasket

The Fernco FTS-3 is a PVC gasket that replaces a traditional wax ring between the toilet and the flange. It fits 3-inch or 4-inch drain pipes and uses a strong flexible adhesive to create a positive seal against the toilet base. The design accommodates floor heights up to three-quarters of an inch above the flange without guessing whether a seal has formed.

Installation Fit And Reuse

The gasket mounts directly onto the flange and adheres to the toilet horn, so no extra sealing compounds are required. Because the adhesive remains on the gasket after removal, the toilet can be lifted for floor work or repositioning and then reinstalled using the same seal. This eliminates the need to purchase a new wax ring every time the fixture is moved.

Ideal For Removable Fixtures

This product suits installers and homeowners who want a reusable, mess-free seal that tolerates slight floor-height variations. It is not intended for drain sizes other than three or four inches, and buyers needing a seal for larger commercial pipe diameters should look elsewhere.

Questions about this item

How thick a floor build-up above the flange can the Fernco FTS-3 seal accommodate?

The flexible PVC gasket compresses to seal floors raised up to 3/4 inch above the toilet flange.

Will the adhesive on this PVC gasket soften or fail if the drain line runs warm continuously?

The seal uses a strong flexible adhesive designed for standard drain temperatures; it is not rated for continuous high-heat exposure.

What size drain pipe must already be in place for this 3-inch model to install?

It fits directly onto a 3-inch drain pipe; a 4-inch pipe would require the 4-inch version.
