Cut hole to the Holesaw size indicated for the UNISEALr you are using Example 3" UNISEALr = 4" Hole (Holesaw) 2. Ensure the hole is clean cut with sharp edges. Irregularities could cause poor seating and ultimate leakage. 3. Insert UNISEALr into hole with the wideside facing the pipe to be inserted. 4. Make certain that the pipe end to be inserted is clean cut. File the edges so that there are no sharp points to cut the UNISEALr 5. Using Detergent, lubricate the outside of the pipe end to be inserted, then push the pipe through the UNISEALr from the large flange side. The detergent will be squeezed off as the pipe passes through the UNISEALr The co-efficient of friction of the rubber holds the pipe tightly in place.
