Sealing Conduit - Interior/Exterior

Hello -

Ran conduit underground from the *pole* back to the basement for utilities - telco and cable tv. Left a drag in there as well. What is the proper / recommended way in sealing the outside pipe or the inside.

In looking at the one for the electrical, they just spray foamed it.

I want this conduit to be ~servicable~ in the event I need to change or add something in the future.

A quick google shows Polywater to be the best product ?

For any penetration into a building that is heated, we seal the pipe with duct seal. It is weather proof and stays pliable for many, many years. I do not recommend spray foam.

I have only known Polywater to make cable lube.
