Types of faucet pipes and accessories

The height and length of the water outlet can be adjusted by replacing the existing faucet pipe. It is also possible to improve functionality such as saving water and preventing water from splashing. The right type and size of faucet pipe can be selected to meet different purposes.  This article describes the different types and sizes of faucet pipes.

Types of faucet pipes and tip components for different purposes

There are different types of faucet pipes and parts that are attached to the end of the faucet pipe to meet various needs and concerns in the water area.

To raise the height of the sink to make it wider / installing a water purifier

Upward-facing pipe

This pipe allows you to raise the position of the water outlet. This makes it easier to wash large pots and pans at the sink, or to fill a bucket with water. It is also possible to install a water purifier that could not be installed due to the narrow space between the faucet and the sink.

Swan Pipe

As the name suggests, this pipe is curved in an S-shape like a swan's neck. The position of the water outlet is higher, allowing for wider use of the sink. Both downward and upward-facing types are available.

To extend a pipe

Telescopic pipe

This type of pipe can be adjusted by stretching or shrinking the length of the pipe in a parallel direction. Since the pipe can be temporarily lengthened, it is useful for cleaning sinks and fetching water. The tip of the pipe can be rotated 360 degrees.

To change the direction freely

Flexible pipe

This type of pipe can be bent at any angle. The flexible pipe can be bent at any angle, allowing water to reach every corner of the sink. There are various types, such as upward, downward, and swan types.

Types of tip components by application

To save water

Kitchen shower

Attached to the end of a pipe, it sprays water in the form of a shower. Even a small amount of water is sprayed out with great force, thus saving water. Suitable for washing dishes, etc.

To reduce water splashing

Foam cap

By attaching a bubble fittings, bubbles (air) are mixed with the water. This foam cap softens the water flow and prevents water from splashing. It also saves water at the same time.

Faucet pipe size

There are two standard faucet sizes defined by JIS. Before purchasing a new faucet pipe, check the size of the part you wish to install.

When the faucet pipe is removed from the existing body, it is divided into the faucet body, pipe packing (U-packing), pipe ring, and faucet pipe (with bag nut).

When looking at the size of the faucet pipe, check the ‘outer thread outer diameter’, which is the threaded part of the faucet body, and the ’pipe outer diameter’, which is the threaded part of the faucet pipe. At the same time, please check in advance whether it is an internal or external thread, as it varies from product to product.

Nominal 13 (1/2)

  • Mounting screw size...W26, 20 threads
  • External thread outer diameter...approx. 26mm
  • Pipe outer diameter...16mm

This is a common size used for water supply in homes, etc.

Nominal 20 (3/4)

  • Mounting screw size...W30, 20 threads
  • Outer thread outer diameter...approx. 30mm
  • Pipe outer diameter...19mm

This is a large diameter size used for commercial and other applications.

Even faucets with a large pipe outer diameter of 19mm can be fitted with a 16mm faucet pipe by using a threaded adapter (pipe adapter). 16mm has a wider variety of pipes than 19mm, so you can change to a more convenient pipe that better suits your preference. In addition, please check each time as the size may differ from the specified size depending on the faucet type (mixer faucet, special faucet, etc.) or manufacturer.

Incidentally, while size is important, it is also important to check the pipe length in advance. Especially for curved faucet pipes, the length from the attachment point to the front of the pipe will differ depending on the degree of bend. To prevent the pipe from sticking out of the sink, take this into consideration when making your selection. Other selection points include whether the bent pipe will not hit the faucet handle and where the water will fall in the sink.
