Fernco Inc FTS-4CF Wax Free Toilet Seal 4x3 Inch

Product Description

The FERNCO INC FTS-4CF is a wax-free toilet seal designed as a direct replacement for traditional wax rings in residential and commercial toilet installations. It fits 4-inch by 3-inch drain configurations and uses a strong, flexible adhesive compound to create a reliable seal at the base of the toilet horn. The adhesive design eliminates the mess and inconsistency associated with wax rings and provides a repeatable, positive seal without guesswork. Licensed plumbers and experienced DIYers working on toilet resets or new installations will find this seal straightforward to apply across a range of subfloor conditions.

This toilet seal is rated for use on all floor types, including wood, tile, linoleum, and carpet. It accommodates floors that sit up to 3/4 inch above the toilet flange, making it particularly well suited for tile overlays, flooring renovations, and in-floor radiant heat installations where the finished floor height may exceed standard flange projection. It is sold as a single unit and is appropriate for any residential bathroom or light commercial application requiring a 4-inch by 3-inch toilet-to-drain connection.

Key Features

• Wax-free adhesive formula bonds directly to the bottom of the toilet for a clean, consistent seal
• Fits 4-inch by 3-inch drain openings
• Accommodates raised floors up to 3/4 inch above the toilet flange
• Compatible with all floor types: wood, tile, linoleum, and carpet
• Ideal for in-floor radiant heat installations where wax rings can soften or deform
• Eliminates uncertainty about seal integrity at installation

Compatibility

Designed as an OEM-style replacement or new-installation seal for standard residential and light commercial toilets with a 4-inch by 3-inch horn-to-drain connection on any subfloor type, including installations where the finished floor is raised above the toilet flange.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson following local plumbing code requirements. Shut off the water supply, drain and disconnect the toilet completely before removing the old seal and cleaning the flange and toilet horn surfaces. Apply the FTS-4CF seal to the toilet horn before setting the toilet onto the flange, pressing firmly to ensure full adhesive contact. Do not reposition the toilet after initial placement, as repositioning may compromise the seal bond.
