Need to seal a gap up to 15mm between a poly rainwater tank and plastic stormwater pipe.

The 90mm plastic pipe enters the tank horizontally through a hole cut in the corrugations. Which sealant would be suitable. As the pipe is attached to a 12m shed wall, the sealant needs to be flexible to allow for expansion.


Unfortunately, we do not have sealant that would be suitable for this application. Polyethylene plastic is very difficult to adhere to.
