Can you use brass as a dialectric union between copper and black iron pipe?
No, brass cannot be used as a dielectric union between copper and black iron pipe. Dielectric unions are typically made of materials that are not electrically conductive, such as plastic or rubber. Brass is a conductive material and would not provide insulation against galvanic corrosion between copper and black iron pipe.
Can copper dwv attach to a cast iron drain system without a dielectric union?
yes. A no-hub coupling or FERNCO (brand name) coupling work well.
How do you join copper pipe to steel pipe?
Depending if you are talking about stainless steel or galvanised steel. Either way, you need to use copper compression fittings, otherwise known as conex fittings in some countries. Also, you need to be aware of galvanic corrosion if you are connecting copper pipes to galvanized steel pipes. The joint will rot away from the electrolytic action in a few years unless you use a dielectric union or other insulating separation.
How do you install a union on a pipe?
You carefully cut the pipe, then if you can push it apart enough to fit one nut and one'olive on each end of the pipe. Now seat both ends in the union. At this point you hold the centre of the union with a wrench and tighten each end nut while pushing the pipe in towards the union. When both ends feel tight, hold each end nut with a wrench and give one final 1/4 turn. That was with a standard brass union, now you can also fit a 'sharkbite' with no wrench, just firmly pushing each end in. With 'sharkbite', however you MUST make sure the pipe ends are smooth and have no sharp edges.
What does the word union mean in the sentence What is the union of A and B?
the word union means together.
Do need to use dielectric union when you have black pipe to brass fitting?
Brass and steel are compatible, Otherwise we could NOT use brass valves with steel piping.
Why Using a dielectric union to join galvanized and copper water supply pipes?
Dissimilar metals in contact to each other cause a Galvanic Reaction resulting in one or both metals corroding and causing a leak. A Dielectric Union separates the two metals by uses of rubber and/or plastic thus preventing a Galvanic Reaction. Also in most Plumbing Codes, you can use a Brass fitting in place of a dielectric union as Brass does not react with Copper or Steel Piping (Galvanize Piping).

Can you connect a copper fitting into a cast iron pipe without a dielectric union?
Certainly, if the pipes are kept dry, and don't carry an electrolyte, such as water.Otherwise, it's a bad idea to directly connect different metallic pipes. In fact, most plumbing codes prohibit such a connection.That's because anytime any two dissimilar metals contact each other -- while in the presence of an electrolyte -- whichever metal has the higher electropotential will corrode, through electrolytic action.So, in the case of copper vs iron, the copper side of the joint will eventually fail due to corrosion -- unless you electrically isolate the two metals.You can do this via a dielectric union, or dielectric nipple. Or, you can use a hardened brass fitting, which resists corrosion and also smooths the dielectric potential between the copper and steel.Of course, another author may have a different opinion (like the one below.) So my advice is to understand the 'why' of electrolytic corrosion, so you can determine whether or not, in your case, a dielectric union is advisable.####Of course , NO Problem and there are many ,many options of doing so.The electrolytic conditions happens when connecting ferrous metals to non ferrous metals that contain zinc (galvanized) if you think about it EVERY SINGLE CAST IRON RADIATOR has a brass shut off valve, Most black steel gas line have a BRASS gas valve. Brass bolts are the best way to go when installing CAST IRON ROOF DRAINSAlso why use a dielectric union when there are dielectric nipples less chance of leakage
Can you screw a copperfitting into a cast iron pipe without a dielectric union?
Of course NOT A Problem as electrolytic action most of the times happen between piping that contains galvanized coating (Zinc) Cast Iron radiators for example have BRASS valves which can contain as much as 85% copper If one looked at the clean outs of cast iron piping the CO's are brass with never any adverse actions
Can copper dwv attach to a cast iron drain system without a dielectric union?
yes. A no-hub coupling or FERNCO (brand name) coupling work well.
Can you join copper and cast iron without a dielectric union?
Indirectly yes. Rivetting, plating, adhesive bonding, but joining these materials could lead to corrosion in wet conditions.
What is the name of the fitting used to connect the water lines to the water heater?
Dielectric union
Can a 2.5 galvanized dielectric union be used to connect black pipe to copper pipe?
Yes

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
How can you find out if you get a pension from steel workers union?
by seeing if you get checks with signatures from people in that union
