Instructions for Using THE ORIGINAL UNISEAL
- Cut hole to the holesaw size indicated for the UNISEAL you are using. (See table below.) Example: 2" UNISEAL = 3" Hole (Holesaw).
- A clean cut is essential to ensuring a leak free installation, we like to use a fine grit sandpaper. You only want to remove the burrs.
- Place the UNISEAL into the hole with the flange (wide side) facing the pipe to be inserted.
- Be sure that all burrs are removed from the pipe, a slight bevel on the end of the pipe will ease installation.
- Lubricate the outside of the pipe to be inserted with water, soap etc , push the pipe through from the
flange side of the uniseal. The uniseal will expand in the hole as the pipe is inserted creating the seal.
