Bung sealing advice please...

About to replace the deck drain tube and was questioning the best solution for making sure it is watertight. Thoughts are a rubber seal (3mm thick) or sikaflex - which do you think is the best option? Diameter of hole is approx 50mm with a 5mm flange. There is a plastic nut which fasterns 'tight' on the inside.

Regards

Looks like the same fitting i had on my valiant. Its the same as 11/2 plastic plumbing waste so the seals and nut from that will fit .
If its the same as mine it has a non return flap in it .
My only concern with sikaflex was getting it out again if it even needed replacing but iether should work ok .

Yep, sikaflex. If it should need to be removed, sikaflex usually 'lets go' with a bit of persuasion. If not, bust it out, it's only a 10 bob nylon fitting and replace it with s/s.

Hi.

I think Sikaflex is the way to go.

As has already been said it will come out again if required with a bit of effort.

Will probably go for the sikaflex route - hopefully tomorrow in my makeshift gazeebo tent - providing it has not blown away over night!

Many thanks.
