Also to know is, can you connect plastic pipe to metal pipe?

Making the connection between plastic pipes such as ABS or PVC and metal pipes such as copper or galvanized steel is very straightforward. Plastic pipe fittings are available as either threaded (both male and female threads are available) or slip (non-threaded for making glue joints).

Similarly, can you connect galvanized pipe to PVC? If you end up having to transition from a male threaded pipe, use a galvanized coupling to create a female connection before making the transition to plastic. Once the adapter is tight, glue a pipe into the other end, and you're ready to run the rest of your PVC or CPVC pipe system.

Beside above, how do you attach plastic to metal?

Tube-based epoxies and two-part epoxy putties are generally able to handle sticking metal to plastic. These types of adhesives take a while to cure and work better if the items are clamped together during the drying time.

How do you seal metal pipe threads?

Can you attach PVC to copper pipe?

You can connect PVC or CPVC to copper in several ways. One common method is to solder a female threaded fitting onto the copper pipe, screw in a male threaded plastic fitting and finish up by gluing plastic pipe to the plastic fitting.
