Pipe ID 3"
Pipe OD 3 1/2"
Holesaw Size 4"
Instructions for Using THE ORIGINAL PATENTED UNISEAL®
1/ Cut hole to the holesaw size indicated for the UNISEAL you are using. (See specification sheet or back of header card.) Example: 3" UNISEAL = 4" Hole (Holesaw).
2/ Insure that the hole is clean cut with no sharp edges. Irregularities could cause poor sealing and ultimate leakage.
3/ Insert the UNISEAL into the hole with the wide side 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 UNISEAL.
5/ Using detergent, lubricate the outside of the pipe end to be inserted, then push the pipe through the UNISEAL from the large flange side. The detergent will be squeezed off as the pipe passes through the UNISEAL. The co-efficient of friction of the rubber holds the pipe tightly in place.
