Any tips for working with metal couplers for installing cleanouts on sewer lines with limited flexibility?

A while back, I used these metal couplers to put in a clean out on a sewer line, and I have to do it again. It was a real headache last time. Any advice on working with these? They’re not very flexible when it comes to fitting new pipe and a clean out.
Here’s my method (still a hassle but slightly less so). Slide your rubber onto the pipe and fold it halfway. Then insert the other piece and fold it back over onto the second piece. Like I mentioned, it’s a bit easier but not by much.
Then slide the metal part on after the rubber part is in position
Yeah, I believe that’s what I tried before. But I noticed that the metal is connected to the rubber, so it doesn’t slide well. I will double-check.
Oh yeah, if it’s attached that way, the method is not good. I prefer using the ones that come in 2 pieces.
How about swapping it out for a rubber one?
I think for underground applications, it’s necessary to use couplers made of both metal and rubber.
Hey , it’s not recommended to use rubber exclusively below ground. It’s better to use metal couplings in areas where the ground may shift, to prevent pipes from sinking.
We can actually use rubber here in the UK, unfortunately. That’s why I brought it up. And it’s important for the pipes to be securely encased to prevent any movement.
Make sure to loosen the clamps more than necessary
Just make sure to add a touch of grease to the pipe. If it doesn’t have a nipple, it should slide on easily.
It’s a lot easier to mess around with the ones you tighten using a screwdriver instead of a wrench or socket
Petroleum jelly
I personally prefer using dish soap and a slim flat blade to make it easier to slide the coupling onto the pipe. These are much simpler in comparison to the 8″ clay pipe to PVC couplings, which can be quite challenging to begin with.
They actually produce them with a greater stabbing depth
Give it a roll. Install it on one end and fold it over. It’s not the simplest task, but it’s not the most difficult either.

Plumber here. That’s a challenge with those bands. They can act like a regular glue coupling at times. The easiest method is to loosen the band and slide it down the pipe. Place the rubber on the pipe end and fold the other side over. It can be tricky to start, but it’s much simpler than struggling with it otherwise.
