Plastic weld epoxy

Unread post by Jaf »

Hi guys. Anyone used plastic weld epoxy? It's for a pin hole leak from the diesel tank breather pipe. The pipe is not available. Taped it up a few months ago with sos tape but it's leaking again.

Thanks.

I've got a diesel Mk1 Xantia going off for scrap. I could strip off this part from the car for you. PM me.

if Richards bits dont fix it cant you cut out the damaged section and join a piece in wit rubber fuel hose????,
when joining plastic pipes with rubber and pipe clamps, to prevent the plastic pipe being crushed on tightening the clamps, insert short lengths of copper/metal inside the end of the plastic pipe

Probably not very HSE suggestion, but I have succesfully sealed small holes and cracks with a soldering iron used lightly like a mig welder. It melts the plastic around and seals it. There is a knack to it without being too heavy handed. I recently has a disastrous leak on my home oil heating (the Tiger Loop deaereator) which had cracked a sprayed over 100 litres of expensive oil everywhere. I used a small gas soldering iron to seal the crack and it worked. Obviously I didn't use it when the oil was spraying around.

If you can bag a replacement pipe that would be best in the long run.

Malc, can say, hand on heart, I've never, ever used my 'bits' on any repairs, plastic or otherwise! :rofl2: :rofl2: :rofl2:

When welding plastics, its useful to have a spare piece of the same grade to act as a filler. This will allow any repair not to be compromised by a lack of material. 8-)

Handyman, have pm'd you.

Thanks for all the suggestions. It's actually the second one to go, I had one off the old tank.

I really don't want to cut it as I'm not sure the corrigated stuff will ever seal. I've had the same problem with pool water pipes. If handyman doesn't have one I will try the repair patch first, didn't think of that. I have some experience of welding and soldering so that's a great idea too.
