Flare fitting threads have a 37-degree cone shape that creates a tight seal when the flared end of a tube is inserted and tightened, making them ideal for high-pressure applications. In contrast, compression fitting threads use a straight thread and rely on a compression ring (ferrule) to create a seal as the nut is tightened, allowing for easier installation and disassembly. While both types of fittings are used in Plumbing and HVAC systems, flare fittings are generally preferred for gas lines, whereas compression fittings are often used in water and air lines.
Plumbing pipe threads are squared and conduit pipe threads are tapered.
screw thread are single threads which means they are not double
The threads
the difference between the min and max effective of your two threads will tell you if there going to clash on assembly
Thread angle is different (55° vs 60°).NPT threads are flattened at the peaks and valleys, while BSPT threads are rounded.Threads per inch (TPI) is different for two (except for a couple of cases).
MIP ==> Male Iron Pipe thread (i.e. threads on outside of fitting) FIP ==> Female Iron Pipe thread (i.e. threads on inside of fitting)
Compression uses a ferrule or brass ring around the pipe that is compressed by the nut into the pipe and against the fitting. There is no such thing as Female Pipe Threads. There are Male and Female fittings, the pipe is the Male side and the fitting is Female. The Male goes inside of the Female. They both have pipe threads. Pipe thread, Compression, and Flare all have different thread pattern so that they cannot be mixed. They all do different jobs.
It is spread on the threads of pipe before being screwed into a fitting so that the threads will make a seal. Since pipe threads are not machined to fit together perfectly the paste makes up the difference and is compressed between the grooves on the two halves.
Plumbing pipe threads are squared and conduit pipe threads are tapered.
Water pipe threads are tapered, electrical pipe is not tapered.
screw thread are single threads which means they are not double
C = cupped end - the type you would slide over another pipe to make a sweat connection FTG = fitting end - the type that slides inside a cupped end, also called a "street" fitting M = male pipe threads FE (sometimes listed as just F, not correct)= female pipe threads The "X" is "by", so C X C is "cupped by cupped", a fitting with two ends such as a coupling or elbow, both cupped for sweating onto a pipe or fitting end. C X C X C would be a fitting with three ends such as a tee, all cupped. C X FTG could be a street elbow or a reducing bushing, one part slides over a pipe, the other inside another cupped fitting. C is indeed a cupped fitting. CMP is compression, but there is no such thing as a copper fitting with a compression connection. There are brass and plastic compression fittings that will fit copper pipe, but not copper compression fittings.
The threads
NPT = pipe Briggs standard = Pipe NFT and NFC and ASAE = bolt
You have a new one installed!ANS 2 - Usually very easy to fit a new faucet, even directly to a pipe. -Many faucets now come with a compression fitting.
A cagoule is more puffy and has threads usually hanging out
A pipe fitting that has both external and internal threads is called a "coupling." Couplings are used to connect two lengths of pipe, with one end having female threads (internal) to receive a male threaded pipe and the other end having male threads (external) to connect to another fitting or pipe. This design allows for versatile connections in plumbing and piping systems.
