Some sealant and metal tape. I also used a band clamp at the appliance adapter to stove connection instead of screws. No leaks and everything is nice and secure. Duravent Pro pipe also.
Got it. Now I have another problem. I sent Duravent an e-mail. The product literature states all connections have built in o-rings. Only the T-adapter I got has an o-ring. I checked the part numbers on the the factory-applied labels on each pipe and they all match the part numbers in the literature so I don't know if that's how the straight chimney sections are supposed to be or if the pipes are mislabeled/mismanufactured.
What did your straight chimney sections look like?
I helped a fellow down the road install his new toy. He purchase PVP at a local stove shop. We found the same thing "some pieces had the o'rings and others did not". All the part numbers were correct. I got on the horn and contacted Simpson on this issue. There reply was some of the pieces were old stock and would mate to the new stock no problem. They recommended we seal the inner pipe joints with hi-temp silicon to make the seal better. We found that the joints in the house still leaked and had to seal the seams and joints on the outside of the pipe as well. All the pipe on the exterior of the house were not sealed to allow easy removal.
So with any of the joints inside the house you probably will find the same thing. You will need to seal them well to stop the leaks.
I have since done other installs with PVP were all the pipe had the o'rings and still found serious leaks and had to disassemble the pipe to seal the crap out of them. They still leaked pretty badly so out came the silicon to seal the seams and joints on the exterior of the pipe. I am not very fond of PVP, But its the easiest stuff to get locally.
Tip, use any color hi temp silicon on the internal joints, But use
permatex Ultra black on the exterior joints to make a neater looking install. FYI
