What is a pipe hub?
As previously stated, the hub of the pipe is the female "bell" end of the pipe, which leaves the male end of the pipe the no-hub end. The no-hub connection option is probably the most used by nonprofessionals due to the ease of installation. All that is needed is a no-hub coupling to attach the drain to the pipe.Apr 20, 2020
What thread is a garden hose?
The US standard was defined by NFPA 1963, "Standard for Fire Hose Connections", then later by ANSI-ASME B1. 20.7, which specifies 11⁄16 inches (27 mm) diameter straight (non-tapered) thread with a pitch of 11.5 threads per inch (TPI).

Is FIP the same as IPS?
IPS in Other Forms When looking for threaded plumbing fittings, you often see the terms MIPS and FIPS. These are based on IPS and simply note that the fitting is a male fitting (MIPS) or a female fitting (FIPS). And some parts have both.Jan 20, 2022
What is a FIPT fitting?
Fipt: Fipt is the term for the female threaded side of the PVC fitting. Female threaded PVC fittings have threads on the inside of the fitting, and can be connected to any PVC item that has a male (Mipt) end. Mipt: Mipt is the term used for a male threaded side of a PVC fitting.
What is a spig in PVC fittings?
Spig: Spig is the term commonly used for spigot ended fittings.
What is a nipple?
Nipples. A length of pipe that is threaded on both ends. Snap. Snaps over pipe of the same size. The most common types are: Slip: The slip fitting is the most common fitting. It is a female fitting that is meant to slip over the end of the pipe you are connecting it to, and is held there with some cement glue.
Can you connect a spig fitting to a PVC pipe?
You cannot connect a spig fitting to a PVC pipe length without first using another fitting because both are the same size. Remember, for spig and slip fittings you always need to use glue otherwise the fittings won't hold. Other than that, you are now ready to go start your project.
What is a fitting in pipe?
Fitting – part of a pipe line used to fit together sections of pipe. Fittings can come in all shapes, sizes, and materials. FPT (FIPT) – aka Female (Iron) Pipe Thread. This is a type of threading that is found on the inside lip of a fitting, allowing connection to a MPT or male pipe threaded end.
What is a MPT pipe?
MPT – aka MIPT, Male (Iron) Pipe Thread – a type of threaded end found on PVC or CPVC fittings where the outside of the fitting is threaded to facilitate connection with a female pipe threaded end ( FPT). NPT – National Pipe Thread – the US standard for tapered threads.
What is a coupling in plumbing?
Coupling – a fitting that slips over the ends of two pieces of pipe to join them together. CPVC (Chlorinated Polyvinyl Chloride) – a material similar to PVC in its rigidity, corrosion resistance, and chemical resistance. CPVC, however, has a higher temperature tolerance than PVC.
What is saddle in plumbing?
Saddle – a fitting used to create an outlet in pipe without cutting or removing the pipe. Saddles generally clamp on to the outside of a pipe allowing a hole to then be drilled for the outlet. Sch – abbreviation for Schedule – the wall thickness of a piece of pipe.

Compression fittings have straight threads and are made of brass or plastic and are often used on soft copper pipe and small-diameter tubing. The angle stop under your sink is one example of compression threads.
What is a nipple and a tee?
They can be male to female and reduce size or change thread type. Nipples are straight fittings with threads on both ends. Couplers are female fittings with threads on both couplers. Tees are couplers that join three sections of pipe or tubing.
What does NPT mean on a pipe?
NPS stands for national pipe straight, and NPT stands for national pipe tapered. Tapered threads become narrower as they extend outward, while straight threads retain the same diameter. Straight fittings have no taper to the body and are sealed to another fitting with an O-ring or gasket.
What is pipe fitting?
Choosing what pipe fitting you need is like selecting the proper Lego when constructing a Lego set. Your project will determine the arrangement of your fittings. If you’re going around the back of a cabinet to get to the ice maker or trying to hide tubing, you'll want to avoid creating leak points. Where you need the water, fluid, or air to go—around a corner or up a pipe—determines what shape or style of pipe fitting to use.
Why is the outer diameter of a male thread smaller than a female thread?
The outer diameter is smaller on a male thread than a female thread because the male end compresses into the female end. 3.
What is NPT thread?
NPT - National Pipe Thread / NPT (Taper) is the American standard thread pattern for pipe connections and has been in use in the U.S. since the mid 1800's. NPT threads are cut at cut at an angle of about 60° along the length of the fitting, and the actual individual threads are cut at an angle of about 1° 47’ from the centerline of the fitting.
What is parallel thread?
Parallel Thread / Straight Thread (no Taper) - NPS - National Pipe Straight. To seal two fittings cut with parallel threads the fittings will rely on a gasket, O-ring, or on the mating of soft copper or brass flanged or tapered surfaces between the two fittings.
Why is tubing so thin?
That's because tubing is too thin (compared with iron or brass pipe) to form a threaded mechanical joint. Both of these threaded fitting types listed above are used in North America, including Canada, the U.S. and Mexico.
What does FIP mean in pipe fittings?
FPT stands for Female Pipe Threads and FIP stands for Female Iron Pipe which both indicate a female fitting with NPT threads. Remember not to confuse NPS (again nominal pipe size) with National Pipe Size - which is NOT a real designation.
What is the taper rate of NPT threads?
NPT threads have a 60° thread angle, the roots and crests are flat and the taper rate is 1 in 16 inch (which means the pipe size will drop 3/4-inch over 12-inches).
What is NPT pipe?
Let's begin by taking a look at a couple of NPT pipe fittings - NPT refers to as National Pipe Threads, which is a term defined by ANSI (American National Standards Institute).
