ftg = fitting. With copper fittings, it indicates that an end is the same diameter as the copper tube so it will slide into another fitting designed for copper tube. The ftg end slides into the C end.

The NIBCO® lead-free* wrot copper solder pressure fitting reducer is used in residential and commercial systems such as potable water, air conditioning and refrigeration. The fitting reducer features a male solder end and solder cup. The fitting provides a means for reducing the size of a line.

Type K Copper Pipe: Type K copper pipe has the thickest wall of all the common types. It is used for water distribution, fire protection, oil, HVAC, and many other applications in the construction industry. Type K pipe is available in a rigid and flexible form and can be used with flared and compression fittings.

Wrought (wrot) copper alloy fittings used for drainage, waste, and vent applications with solder joints are manufactured to the requirements of ANSI/ASME B16. 29 – Wrought copper And Wrought Copper Alloy Solder Joint Drainage Fittings – DWV. All 90 degree fittings shall be pitched so that a slope of 0.25 in./ft.

Copper pipe is almost pure copper manufactured to the requirements of ASTM B 42 – Standard Specification for Seamless Copper Pipe, Standard Sizes. Joints in seamless copper pipe can be threaded, flanged or brazed to fittings of the appropriate joint configuration.

Different types of plumbing fittings come in the same material as their pipe counterparts, whether CPVC, brass or galvanized. In general, use PVC fittings for PVC pipe, copper fittings for copper pipe and so on.

All you have to do is clean your copper item with a mixture of table salt and vinegar and then observe the color change to find out if your object is made of copper. If the color that comes out after cleaning shinning reddish-brown, then it is indeed copper in a considerably pure form.

Blister copper is the purest form of copper after electrically refined copper (100% pure) which is obtained in this process.

Copper is actually diamagnetic, which means magnets repel it rather than attract it. So, no, your copper item won’t stick to the refrigerator. If you put a magnet on your metallic item and it sticks, then it’s most likely iron, steel, or some other ferromagnetic material.

“Strike your copper item against something and listen to the sound,” says Martin. Real copper is a soft metal and should deliver a deep and mellow sound, as opposed to alloys that are more likely to produce a clear, ringing bell-like sound.” Other materials will produce different sounds.

In our everyday experience aluminum doesn’t stick to magnets (neither does copper). Most matter will exhibit some magnetic attraction when under high enough magnetic fields. But under normal circumstances aluminum isn’t visibly magnetic. This is easily tested by putting a very strong neodymium magnet near aluminum can.

Bare bright copper wire is defined as clean, bare, uncoated, unalloyed copper wire, not smaller than No. 1 copper consists of clean, untinned, uncoated, unalloyed copper wire and cable, not smaller than No. 16 gauge. No. 1 copper also can consist of clean, unsoldered copper tubing and clean copper solids/punching.
