How should I seal 4" black tubing at a T

I have installed black 4" tubing at the downspouts off the home and ran underground to keep water away from a newly installed pool. The black tubing is connected to a T. I understand that stainless steel screws can be used to support the T's and tubing. Although what type of Tape can be used and wrapped around the joints to secure a tight fit?

I used white schedule 40 PVC on the other side and this was put together with primer and glue so there is no concern.

I do not know if standard duct tape will last underground in the dirt. I am assuming it will. Or if I can use the silver tape that is used for duct work in an air conditioning system. Is there any special tape or filler that will be permanent?

Thanks!

I doubt any tape would work well and I doubt you really need it. If you are talking about the corrugated pipe and associated fittings, I've never seen the joints sealed on them. They are just pressed together and put in the ground. Any small amount of leakage is just absorbed by the ground in the area.

Yes, it is the corrugated pipe and fittings and the pitch is pretty steep. Just want to keep them sealed like the pvc glue. Other option is concrete, small amounts. Did not want soil moving around changing pitch. Thanks

What I used

It was a little cold outside so I used a heat gun to heat up the black T and piping and used the silver tape from Home Depot or Lowes after using a few stainless steel screws to support the sections. Should have taken pictures. After this black duct tape all the way around and buried in the dirt. I beleive this will work fine over the years and I will not have any issues.
