Types of tap fitting

A tap fitting is a device that connects the water supply pipe to the faucet, enabling water flow from the faucet. Tap fittings are commonly known as tapers and are available in various sizes, materials, and designs to suit different types of faucets and plumbing systems.

Tap fittings are essential for any plumbing system. They are designed to provide a secure and leak-proof connection between the water supply and the faucet. They come in different types and sizes to fit various plumbing systems and devices. Some of these tap fittings include:

• Compression Tap Fitting:

  Compression tap fitting is popular with DIY enthusiasts because it is easy to install. It is designed to create a leak-proof seal using a brass olive and a compression nut. The olive is fitted onto the pipe and secured using a compression nut. Compression tap fittings come in different sizes and designs to fit various pipes and applications.

• Sweat or Solder Tap Fitting:

  Sweat or solder tap fittings are commonly used in copper piping systems. They are designed to create a permanent joint that is water-tight and strong using soldering techniques. The fitting is inserted into the pipe, and a torch is used to heat the solder ring, melting the solder, which then flows into the joint and cools to form a strong, leak-proof joint.

• Push-On Tap Fitting:

  These tap fittings are straightforward to install since they do not require any tools. They are ideal for quick and easy plumbing connections. The pipes must be clean and square so that the fitting can be pushed onto the pipe. Once the fitting is installed, it creates a leak-proof seal due to the O-ring and the grab ring, which prevents the pipe from sliding out.

• Female / Male Threaded Tap Fitting:

  These tap fittings are commonly found on metal and PVC pipes. They are designed to create a secure connection using a threaded male or female fitting. The male threads are screwed into the female fitting to create a leak-proof connection. Tap fittings with metal threads create a stronger connection than those with plastic threads.

• Angle Tap Fitting:

  Angle tap fittings are designed to connect pipes that meet at a 90-degree angle. They are commonly used in tight spaces, and their compression design makes them easy to fit onto a water supply line. They are versatile and come in various materials, such as plastic or copper, to fit different types of plumbing systems.

Functions and features of tap fitting

When it comes to functions, tap fitting is essential for connecting pipes to fixtures, enabling water flow for various household tasks. Tap fittings have different features, which are as follows:

  These tap fittings come in different thread types, such as BSP (British Standard Pipe) and BSPT (British Standard Tapered). The BSP and BSPT threads are compatible with most plumbing applications. Other thread types are M (metric threads) and H1/2 (half-inch threads). The metric threads and H1/2 threads are commonly used in faucets and shower heads.

• Sizes

  Tap fittings are made in different sizes to accommodate various pipes and fixtures. Common sizes include 1/2 inch, 3/4 inch, and 1 inch. The half-inch size is commonly used in household water supply lines, while the 3/4-inch size is often used for outdoor faucets and washing machine connections.

• Connection types

  Various tap fitting connections are available, including compression connections, soldered connections, and threaded connections. The compression connection provides a watertight seal without the need for tools. Threaded connections are easy to install and provide a strong connection, while soldered connections are permanent and used in copper pipe systems.

• Finishes

  Tap fittings are made in different finishes to enhance their appearance and resist corrosion. Common finishes include chrome, nickel, and brushed stainless steel. The chrome finish offers a high-shine appearance and is easy to clean, while the nickel and brushed stainless steel finishes offer a warmer tone and are more resistant to fingerprints.

Scenarios of tap fitting

There are several applications for tap fitting, including:

• Water Supply: Tap fittings are installed on pipes to connect water taps or valves. The threads on the fitting allow easy attachment of taps, which can then be attached to sink counters using a locking nut. This application is common in homes, offices, schools, and any place with water taps.
• Hydraulic Systems: Hydraulic systems use tap fittings to connect pipes or hoses. One end of the fitting is screwed into the pipe, while the other end can be connected to the hose or another fitting. The two pipes or hoses are then connected for fluid transfer. This application is common in construction equipment and machinery.
• Air Conditioning: Tap fittings are used in air conditioning systems to connect refrigerant lines. The fittings create a secure connection so refrigerant can travel through the lines without leaking. This application is also popular in commercial and residential AC systems.
• Automobiles: In cars, tap fittings are used to connect metal brake lines to various components, like the master cylinder or brake calipers. The fittings ensure a secure connection so brake fluid can be transferred and the brakes can be activated. Additionally, power steering systems use tap fittings to connect hoses to steering racks or pumps.
• Fuel Delivery: Tap fittings connect fuel lines to the gas tank, fuel pumps, or carburetors in vehicles. They create a secure connection so fuel can be delivered to the engine without leaks. Additionally, tap fittings can connect oil lines to engines or other components, like the oil cooler or oil filter.
• Vacuum Systems: Tap fittings are used to connect hoses to various components in vacuum systems. They provide a secure connection so air can be removed from the hoses and a vacuum created. This application is common in industrial and commercial settings.
• Refrigerators: Tap fittings connect various components in refrigeration systems, such as evaporator coils or compressor units. They enable the transfer of refrigerants so cooling can be achieved. This application is popular in commercial and residential refrigerators.
• Industrial Applications: Generally, tap fittings connect pipes, valves, or other components in various industrial settings. They enable the transfer of liquids or gases and are widely used in manufacturing plants and refineries.

How to Choose Tap Fitting

Choosing the right tap fitting for a specific application involves taking several factors into consideration. Here are some of them:

• Application

  Consider the application for which the tap fitting will be used. Is it for plumbing, connecting hoses, compressed air systems, or something else? Different applications require different types of tap fittings. For example, hydraulic tap fittings are suitable for fluid power applications, while pneumatic fittings work well with compressed air.

• Material

  The material of the tap fitting is crucial for durability and performance. Common materials include brass, stainless steel, aluminum, and plastic. Brass and stainless steel are popular for their corrosion resistance and strength. Consider the environment where the fitting will be used to determine the best material, for example, coastal areas with high humidity require corrosion-resistant materials.

• Compatibility

  Ensure the tap fitting is compatible with the pipes or hoses it will be connected. Check the size, thread type, and connection method. Common thread types are NPT (National Pipe Tapered), BSP (British Standard Pipe), and metric threads. Compatibility prevents leaks and ensures a secure connection.
