Just a word of warning about this epoxy adhesive. It arrived without instructions, what you see in the pic above is all you get. It is left to your'good British common sense' to work out what to do with it. Oh dear.
I eventually concluded that the plug at the E end turns a quarter turn and can then be removed, and replaced by the tube dispenser. In the other end are two blue plugs, which I rumbled can be removed by screwing screws into them and pulling. Then I could screw 2 more screws into the pistons and push them in, thus expelling the adhesive. The dispenser tube then got blocked, so I threw it away and expelled the two components onto a piece of card, and mixed it with another screw. I then applied it to the item needing repair, and left it 24 hours to cure.
I replaced the plug on the end. I discarded the blue plugs. I put the container back for use later.
As described in my Vectra starter thread, on a test piece, after 24 hours the adhesive had cured well, and withstood 24 hours in boiling water without softening or weakening. I then used it to repair my Vectra plastic coolant pipe. If it fails I will tell you.
