With the Insitu-Seal you can make a 90° connection into twinwall and ribbed pipe systems as well as plastic wells like ULTRA, OPPTIRIBB, TERRA, PRAGMA, UPOROL.

By drilling a hole into the pipe or well, the Insitu-Seal is then inserted to allow the connecting pipe to be positioned until it reaches the bottom of the seal. The Lauridsen Insitu-Seal is manufactured in SBR, EPDM or NBR rubber.

A 90 mm deep hole saw is required for the installation of the Insitu-Seal as normal saws do not cut deep enough on some ribbed pipes. These are available here.
