Adhesive – Best Glue for Plastic to Metal Without Pressing Surfaces Together

adhesive

I need to glue a plastic thingy inside a metal tube. There is a notch for it to fit in, and it is slightly tricky. Therefore I do not want the glue to soldify too quickly. Also, I cannot press on the surfaces where the glue will be, but it is pretty tight.

I do not know what type of plastic it is, but it is hard. It does not bend. The metal is stainless steel I guess.

Edit: it is not outdoors or under water. Normal house temperature.

What sort of glue should I be looking for?

Epoxy. But forget brand. Look at speed.

Nothing annoys me more than people cheerleading for brand X, and completely ignore brand X's material characteristics and whether they are a good fit for the application.

Epoxies are sold in a variety of speeds from 1 minute to 48 hours. Some even will never cure unless autoclaved. You need to select a speed that is appropriate for you. Slower is better for a novice.

Additives to the epoxy are also appropriate to discuss, as they help epoxy be a strong filler, a bulky filler, stiffen up its flowability, etc. Any chandlery or plastics store should be able to help with that.
