fight corrosion and doorlocks

[Selahdoor]

you mean the pex on the pin as in the first Photo?
would that be all?

I need to slam the doors hard in order to stay shut, for all I know that might be caused by the pression all the door rubber puts on the door?

I have difficulty in seeing where a piece of pex would be the solution!?

As far as I know, such a door should close smooth, without the (reasonable) effort I now have to use?

I'll see if I encounter such material (if they know that over here?)
Pex, is that the waterline? does it also has a layer of aluminium in it?

Yes, I mean put pex on the pin.

Here is my thread on the fix for the problem: https://www.oilburners.net/threads/door-latch-fix.89587/

Difficulty see it as the solution... Yup. I know. That's why I said you'd be amazed. I didn't think it would make much of a difference either. But it did.

Most people use PEX. (None of these have aluminum inside. But if yours does and it fits onto the pin, I don't see how that would be a problem.)

I used CPVC. (It was an intermediary, here in the US, between PVC and PEX.)

Did you try the pex on the door pin? Did that work for you?

Here is a Google search, lots of info on the Striker bushings etc... Yours are gone, so the door does not fit tight against the door seal.

Here is the USA we have a type of plastic water pipe called "PEX". It`s what the guys are talking about.

Open the door, grab the lower edge and lift up and down, if you feel any loosness, the Hinge pin Bushings are worn out.

There are a few You Tube videos in the mix.
Or do a search on YT.
