A copper-to-brass threaded fitting has either a male or female threaded end, and the other has an inlet for a copper pipe. The copper pipe is joined to the brass fitting with melted solder. As brass has a greater density than copper, it takes longer to heat up to the point where the solder will melt.

Similarly, you may ask, can I connect copper to brass?

As an alloy of copper and zinc, brass is compatible with copper, and manufacturers produce many common plumbing fittings with the material. Solder adheres as well to brass as it does to copper, so the fittings are usually molded with slip joints so you can solder them to the pipes.

Subsequently, question is, do you use Teflon on brass fittings? teflon tape and firm is sufficent because if you're just jaming the brass together you can break the seal provided by the teflon or similar, if using unions they seal brass to brass and use the above mention nudge and grunt rule, just be carful not to mishape the fitting as brass can crack or bend with undue force.

Herein, can copper be threaded?

The copper for plumbing is actually tubing, never threaded, but attached to threaded fittings that are sometimes copper (thick copper) or brass, usually by soldering, brazing, or mechanical connection (press fit, push to connect, etc.).

Is it OK to connect brass to stainless steel?

Connecting stainless steel plumbing pipes to brass fittings and pipes is risky. In the case of stainless steel (410) and brass, they are seven metals apart, which means they would be likely to corrode if connected directly. When it comes to stainless steel (301, 304 and 310) and brass, they are only two metals apart.

Does Teflon tape melt when soldering?

Yes, it can destroy the dope and/or teflon tape as well as any sensitive seals, temperature compensators and plastic inside the brass body. Solder the pipe and fittings together so that you have several inches of copper pipe, THEN thread the threaded end into the brass body.

What happens when copper touches metal?

Galvanic corrosion is caused by self-induced current created by electrical potential of two dissimilar metals in contact with an electrolyte. It can occur when two dissimilar metals (such as copper tube and steel pipe) are connected in the presence of an electrolyte.

Do you need dielectric union for copper to brass?

If all of your water piping and connections from the copper to other fixtures or devices are copper or brass (or plastic) you're fine without adding dielectric unions. But it's still steel and In a direct connection to copper will corrode.

Can you silver solder brass to copper?

afaik any silver solder will work for brass and copper. Sil fos doesn't need a flux for copper but does for copper alloys. Easyflo is a common and works well.

Can copper and steel touch?


Since copper has one of the highest galvanic numbers or nobility of the active metals, it will not be harmed by contact with any of them. It will, however, cause corrosion of the other metals if in direct contact.

Does brass react with steel?

As the series suggests, steel and aluminum are relatively compatible, but if brass and steel contact, the steel will corrode because it is more anodic than the brass. The aluminum will also corrode where its exposed surface contacts the brass plate because brass is more cathodic.

Can you melt copper with a torch?

Scrap copper can be melted in order to create works of art or simply to pour into ingots for easier recycling. You can melt copper at home as long as you have a torch that is capable of reaching 2,000 degrees Fahrenheit.

Do you use flux when brazing copper?

A fluxing agent (or a controlled atmosphere as found in furnace brazing) is required for all brazing and soldering applications. No additional flux is needed, although a small amount of flux may be used for applications with prolonged heating times to improve the wetting action of the filler metal.

How do you bond brass to brass?

When you need to glue brass, be sure not to choose a glue that is brittle or that expands.
  1. Which Glue is Best? The glue most suited for gluing brass to surfaces is 2 part Epoxy (Polyepoxide).
  2. Preparing the Surface. Metals such as brass require a bit of roughing-up to encourage a better bond.
  3. Keeping It Together.

How do you remove solder from brass?


Just heat the plate from the back side with a small torch - don't over do it - when the solder melts, just remove the flame and wipe the solder off with a rag. (use gloves). The solder forms an alloy with the brass, so you will still need to use steel wool or fine paper to remove the last of it.

Can you weld brass to brass?

Brass, an alloy of copper and zinc, is a highly useful metal that has many applications in both the commercial and personal industries. Paint this onto the brass surfaces that you intend to weld. You should use either a braze-welding flux or one that is specially created for oxyacetylene welding.

What is brazing VS soldering?

Soldering is a joining process in which the filler metal melts completely below 450C (840F), whereas brazing is a joining process in which the filler metal melts completely at temperatures above 450°C (840°F).

Can you forge weld copper?

Iron and even some hypoeutectic cast-irons can be forge welded. Some aluminum alloys can also be forge welded. Metals such as copper, bronze and brass do not forge weld readily. Copper and its alloys are usually better joined with cold welding, explosion welding, or other pressure-welding techniques.

Can you mix copper and galvanized?

Galvanized pipes should not be connected directly to copper pipes, period. The only time one can successfully replace a section of galvanized pipe with a section of copper is to make use of a dielectric union to ensure the metals do not have direct contact. Brass is an alloy of copper and nickel.

Can copper be bent?


Copper plumbing pipe can be bent properly either with a bending spring or a proprietary plumber's pipe bender which reduces the number of fittings that need to be used. Copper plumbing pipe can be bent properly in two ways. If you attempt to bend copper pipe without either of these tools it will kink.

What is brass made of?

Brass is a metal alloy that is always made with a combination of copper and zinc. By varying the amount of copper and zinc, brass can be made harder or softer. Other metals—such as aluminum, lead, and arsenic—may be used as alloying agents to improve machinability and corrosion resistance.

How do I stop my brass from leaking?

Steps to follow when using Teflon Tape
  1. Tightly wrap the tape around the male pipe, 3-5 times over and clockwise in the threads' direction.
  2. Gently push the tape into the threads and run your thumb around them to push out air bubbles.
  3. Then tightly screw the fittings back together.
