Fernco Inc FTS-3 Wax Free Toilet Seal 3 Inch

Product Description

The FERNCO INC FTS-3 is a wax-free toilet seal designed to create a leak-tight connection between a toilet horn and a 3-inch drain flange. A strong, flexible adhesive compound forms the seal directly against the base of the toilet, eliminating the need for traditional wax rings. The FTS-3 accommodates floors raised up to 0.75 inches above the toilet flange, making it well-suited for tile, hardwood, linoleum, carpet, and other finished floor surfaces. Licensed plumbers and experienced DIYers install this seal during toilet setting or resetting operations.

The FTS-3 is particularly useful in residential and light commercial applications where floor height varies or where in-floor radiant heat systems are present. Radiant heat installations can soften and deform conventional wax rings over time, leading to failed seals. The flexible adhesive construction of the FTS-3 maintains its integrity regardless of floor temperature, making it a dependable choice for these installations. It is sold in a package quantity of 20 units, making it practical for plumbers servicing multiple fixtures on a single job.

Installation Notes

Installation is performed by a licensed plumber following local IPC-referenced plumbing codes. Shut off the water supply and fully drain the tank and bowl before removing the toilet. Clean the flange and toilet horn thoroughly before applying the seal to ensure proper adhesion. Do not reuse the seal once compressed, as the adhesive bond cannot be reset after initial seating.
