Bond PVC to common plastic

Jul 19, 2007 11 Replies

I've got an small odd-ball application where I've gotta bond a length of 3" sewer PVC to a little round plastic food container.



PVC cement? Epoxy? Other??

No sacrificial pieces to try it on?

I believe the PVC cement works on like sched 40 pipe so well it because it fuses/melts it. Airplane glue on models the same from what I remember (long as they held till the 4th of July when I would blow them all up).

I'd try epoxy first, but it depends on the food container. Many are made from polyethylene based material and nothing sticks to them. Experimentation is in order.

Improvise a bulkhead fitting for a mechanical seal instead of glue:

Smacking myself in the head----- I'm not the OP, but I've had a pool strainer sitting on my bench for several months while I pondered how to replace the inlet pipe. I've tried PVC cement with no joy. This will do it!

Thanks, Richard, this is the perfect solution.

50-60 pounds of pressure.. . . ]

You need to know the plastic composition of the food container. Off hand, if polystyrene, PVC cement might work. PET - epoxy might work. PE - nothing common.

If it came down the sewer, it's probably not worth saving no matter how yummy it looks.

Thanks for most responses.

I tested a tiny pvc cement bond. Didn't look too solid.

I ran all over town looking for a slip-on cap for this 3" pvc that hasn't been made for years. Finally found one. Voila!

might be better to use a fernco ftting.

50-60psi is trivial...

I've purchased this locally at Home Depot in 75ft lengths.

Watch out... Some other varieties look just about the same, but the inside of the fittings was considerably smaller. Note that this hose also comes in 5/8" (often mixed on the rack) so watch for the 3/4".

I'm still watching for a deal on 200psi, 1" air hose... But in the meantime I'm using this with some brass adapters on the ends. :)
