Yes, this happens quite often in older houses, copper pipe can be threaded; thus one can join them and there are several fittings that can be utilized.
On the other hand, copper tubing (K, L, M, and DWV) can be joined depending on which of the following application method is used:
- For copper tubing to galvanized water supply, one would use a dielectric nipple or union to prevent electrolytic action from taking place or dezincification of the galvanizing pipe.
- If these lines are for waste or venting, the Mission Rubber Company LLC has various types of couplings that can go from tubing OD to pipe OD without the dangers of mixing ferrous and nonferrous metals .
- For copper tubing to IPS you can solder, braze a male adapter and use the dielectric union, use a copper x galvanized dielectric union, or copper by female adapter and a dielectric nipple .
- If your connecting to a Durham system and the galvanized pipe has a Tucker coupling or a Kennedy tee wye, then you can use lead and oakum without the fear of mixing dissimilar metals as the lead is nonferrous metal but has no adverse effect with galvanized or copper pipes.

What do you need to connect copper to galvanized pipe?
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple
Is galvanized piping ferrous?
Yes.
Should galvanized iron pipe be used for water systems?
No. Galvanized pipe is what they used to use, and now should either be replaced with modern type of water pipe such as PEX or copper. COMMENT: Complete agreement. Galvanized served it's purpose and did bring water into a lot of people's homes for a lot of years. That was then, this is now. Today, it would be a dead last choice for a plumbing system.
Can you use galvanized connections on gas iron pipe?
Most codes do not allow Galvanized piping/fittings on gas piping. I have used galvanized pipe/fittings on exterior gas piping before in the state of Michigan but other states do not allows this. Check with your local code authorities.
What color is galvanized piping?
purpleThe color of zinc
Can brass be galvanized?
IT IS PART Galvanized don't you knowGalvanized is ZINC coating on black steel and YELLOW BRASS piping is 40% ZINC and 60% Copper and RED BRASS is 85% Copper and 15% Zinc=The problem with TOO much Zinc content is dezincification where the piping becomes brittle and to little zinc and the brass is too soft as the higher copper content.==Mixing Galvanized steel and brass or copper causes a condition of electrolytic action as your mixing ferrous metals and non ferrous metals. ( this is first year apprentice training) to prevent the electrolysis one should use a dielectric fitting=
What is ferrous piping?
Any piping containing Iron, usually Cast Iron, Steel & Galvanized pipe.
Can you connect copper to galvanized using only a bronze fitting?
There are copper fittings that will connect to galvanized.
What fitting is required to join copper with galvanized pipe?
A threaded copper fitting on the copper side, male or female, and the galvanized is screwed into it.
Should the galvanized pipes in your home be rusting after 19 years?
Depends on the water quality and what type of galvanized piping was used
What is the point of copper pipes?
They don't rot out like galvanized does, easier to work with, good with pressure.ANS 2 - ALL copper pipes eventually develop pinholes. MUCH better to go PEX for interior water piping !
Why was galvanized pipe used for water supply in older houses?
Because1- water conditions would not allow copper tubing do to the hardness and PH factor2- Labor was cheap and threading galvanized was cheaper then installing copper3- Galvanized is still used in many locations as people do not like to drink water coming out of toxic plastic piping
