Fernco Wax Free Toilet Seal Instructions

Wax always worked in the past so why change now? Because Now There is a Better Way!


Wax does not standup to heat making it a poor choice for use with radiant floor heating.
Fernco's Wax Free Seals are made from PVC and will not break down. Our seal is designed to be a permanent part of the plumbing system upon installation.


If there is a main line backup, wax will not hold much head pressure and is likely to fail.
Fernco's Wax Free Seals are UPC approved. UPC certified to provide a water and airtight connection between the water closet and sanitary drainage system. Conforms to the industry standard ASTM A 1045


Anytime the flange is lower than the finished floor, you need more wax. Unless the flange is installed "over" the floor, it takes more than a single wax ring to seal.
Fernco's Wax Free Seals long neck will make a positive secure connection regardless of flange height.


Each time the toilet is removed a new wax seal must be installed.
With Fernco's Wax Free Seals toilet can be pulled and replaced without changing the seal.


Wax seal removal is a disgusting, sticky, messy job.
Fernco's Wax Free Seals are Clean, Quick, and Easy to install or remove.
