How to measure NPT fittings and pipe sizes?
Measure the Outside Diameter (OD) of your pipe or pipe fitting:
- Wrap a string around the pipe
- Mark the point where the string touches together
- Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
- Divide the circumference by 3.14159
What are standard copper pipe sizes?
What are standard copper pipe sizes? In the plumbing trade the size of copper tubing is measured by its outside diameter in millimetres. Common sizes are 15 mm and 22 mm.

What is the standard size pipe for plumbing?
The most common pipe diameter for water mains is 6 to 16 inches, with 8, 10, and 12 inches also being used. Branch lines providing service to individual homes, offices, buildings, and businesses vary in size from as small as half an inch in diameter up to 6 inches.
Can you mix plastic and copper plumbing?
Interestingly you can join copper and plastic with a lot of the same fittings; a lot of people don't realise you can join a bit of plastic pipe with a compression fitting.
Can you use a 22mm compression on 3/4 pipe?
3/4 and 22mm are not compatible.
What is the most common type of copper for water lines?
Solder-connected rigid copper is the most popular choice for water supply lines in modern buildings. In situations where many connections must be made at once (such as plumbing of a new building), solder offers much quicker and much less expensive joinery than compression or flare fittings.
What is a type Z pipe?
Type Z is a thinner walled pipe, also used for above-ground service, including drinking water supply, hot and cold water systems, sanitation, central heating and other general purpose applications. In the plumbing trade, the size of copper tubing is measured by its outside diameter in millimeters.
What is soft copper tubing?
Soft copper tubing in a close quarters tubing cutter. Copper tubing is most often used for heating systems and as a refrigerant line in HVAC systems. Copper tubing is slowly being replaced by PEX tubing in hot and cold water applications. There are two basic types of copper tubing, soft copper and rigid copper.
What type of copper is used for refrigerant lines?
It can be joined by any of the three methods used for rigid copper, and it is the only type of copper tubing suitable for flare connections. Soft copper is the most popular choice for refrigerant lines in split-system air conditioners and heat pumps .
What type of tubing is used for underground burial?
Type K has the thickest wall section of the three types of pressure rated tubing and is commonly used for deep underground burial, such as under sidewalks and streets, with a suitable corrosion protection coating or continuous polyethylene sleeve as required by the plumbing code.
Why is copper water pitted?
Copper water tubes are susceptible to cold water pitting caused by contamination of the pipe interior, typically with soldering flux; erosion corrosion caused by high speed or turbulent flow; and stray current corrosion caused by poor electrical wiring technique , such as improper grounding and bonding.
What is 8 mm tubing called?
Tubing in 8 mm and 10 mm outside diameters is called a "micro bore" and is easier to install, although there is a slightly increased risk of blockage from scale or debris. It is sometimes used for central heating systems, and 15 mm adapters are used to connect it to radiator valves.
