Periscope dryer vent to ceiling duct?

Is this possible? My combo washer/dryer has small little space. Flexible dryer hose cracked, so I replaced w semi rigid. Duct comes from ceiling (it vents horizontally outside, don't worry.)
Connections aren't great and I left too much length, making it heavier. Difficult to attach 4 inch end to 4 inch duct but spent $$ on some adapters. Now I wonder about a long periscope might last longer, allow dryer to be set back further so I can fully open fridge door. .
Is that an OK idea, with 5.5 ft from dryer to ceiling duct.?

Welcome to the forums.

A long periscope ? Have no idea what you are talking about. Can you explain what it is ?

Are you referring to this style of telescoping duct?

5.5' of dryer duct is fine, most dryers can handle 20-25 of equivalent duct length (including elbows).

That vent but a real pain to install. be sure you have connected to dryer before you push dryer back in place.

Thanks for input. I read about that extra long periscope vent, sound like I should buy a lot of metal tape to seal up seams and double check instructions.
​​​​​​Trickiest part of my setup is tight space, not just for dryer but me getting my body out of closet before shoving the (tall) All in one unit back in .
​​​ Really poor choice of placement when they built this, but not sure how many choices they had.
Thank​s again for your input!
