Brass is an excellent metallic alloy. It contains copper and zinc, thus combining the effect of the two. It’s a favorite metal in plumbing pipe fittings. Different types of brass pipe fittings are available with a lot of specs.

Brass Pipe Fittings:

Brass pipe fittings are the joints that connect two parts of the fittings. Brass pipe fittings are of different shapes and sizes. Every plumbing system needs a joint or some fitting. They perform their enhanced functions and help to lead a smooth flow.

Brass is one of the favorite metals in the plumbing industry. It has a wide range of properties. Let’s check out the properties of brass in the pipe fittings.


Properties of Brass:

  1. Resistance: Brass fittings are resistant to corrosion. They can survive well under harsh conditions. Brass can avoid rusting for a very long period. The fact is that brass is also resistant to high mechanical stress. It means it can perform under mechanical pressure.
  2. Durable Nature: Brass fittings can easily undergo heavy-duty work. It makes brass equally effective for homes and industries. It stays for years without cracking the surface of the product. Brass can easily withstand hot water in pipelines.
  3. Versatility: Brass pipe fittings are versatile. You can find a single brass fitting in a considerable variety. Industries produce brass products on a vast scale. It is because of its widespread use. Different types of brass pipe fittings are available in many shapes.
  4. Temperature Range: We know that brass is an excellent product for hot water treatments. It shows brass fittings can bear high temperatures without getting damaged. It has good conductivity and can withstand more Temperature than other metals.
  5. Malleable: We often need to mild the shapes of fittings to adjust them. Brass has the quality of malleability. It means brass pipes can easily mold into different shapes. It can be adjusted in tight spots by heating and molding.

Different Types Of Brass Pipe Fittings.

Brass pipe fittings come in different shapes as per their use. The most well-known and common types of brass pipe fittings are the following.

Brass Elbow Fittings

  • Brass elbow fittings are curved. They change the flow direction of liquid across a pipeline. Elbow fittings are present in different sizes and materials. Yet, brass elbows are the most trusted ones. Elbows are widely used and are required in practically every plumbing system. Two types of elbows are used: 45° bend and 90° bend.

45° Bend brass elbow connects the pipe to change direction at 45 degrees. At the same time, we use the 90° elbow to connect pipes at 90 degrees.


Product: Forged 45° Brass Elbow.

Material: Brass.

Size: 1/4×1/8

Thread: 1/8 NPT.

Working Temperature: High Temperature.

Applications: Air Drill, Air Line, Gas, and fuel system.

  • Brass Couplings: When we need to connect the two pipes of the same width, we install coupling fittings. The coupling serves as a bridge to connect two identical pipelines or to replace leakage. When a piece of pipe is broken, the coupling can be used at that point by cutting off the broken or damaged part and installing the coupling.

Coupling comes in two types as per their structure. Slip coupling has an easier setup. It contains two pipes tuck into each other. One of them can be slid to fix the damaged pipe. Compression coupling prevents leakage between two pipes. It has seals on both sides that stop leakage immediately.


Straight Brass Coupling.

Material: Brass or DZR

Size: 20×20

Pressure: 1.6 Mpa

Working Temperature: -10°C to 80°C.

Applications:  Water, gas, and oil pipelines.

  • Brass Adapters: Brass Adapters modify the threaded shape of a pipe’s plane ends. Materials with bendable qualities can be used to make threads. There are two ends to brass adapters. One is threaded, while the other is unthreaded.

Threads of adapters are of two types. Male threads are present outside, and female threads appear inside. Bolt is an example of a male adapter but an example of f female adapter.

  • Brass Reducers: A brass reducer is a type of fitting that reduces the diameter of a giant pipe. It’s got a decreasing structure to it. One side of the fitting is quite significant to connect with a larger tube. The second opening, on the other hand, is smaller and divides larger areas into smaller ones.

Brass Reducers come in two types: eccentric and concentric. There is a slight distinction between them. Because of their cone-shaped construction, concentric reducers may have an air batch. On the other hand, the eccentric reducer has a parallel edge to the connecting pipe that prevents air from getting stuck.


Plain Brass Hex Reducer.

Material: Brass, DZR.

Size: 3/8-4.

Thread: ISO7(BS21), ISO228-1(BS2779).

Max Pressure: 1.6MPa.

Max Temperature: 200°C.

Applications: Hydraulic System. Natural Gas and Refrigeration.

  • Brass Unions: A brass union and coupling in function. The pipe is held in place by a nut in the center of the union. Union has a detachable structure. A coupler is not detachable when it is fixed. A union has male and female threads present in it.


Brass Straight fitting type union.

Material: Lead-free regular brass.

Size: 1/4F to 3/4F.

Pressure: 1000Psi (Barstock), 125Psi (Casting).

Thread: Male, NPT.

Working Temperature: -40°F to 250°F.

Applications: Oil, gas, and plumbing purposes. Also usable for steam.

  • Brass Plugs:  Brass plugs seal the end of pipelines. The seal may be temporary or permanent. Usually, we use a plug when we need to repair a specific portion of the pipe. During inspection or repair, the plug stops the flow from the supply line. A plug has male threads. We connect female threads of pupe to male threads of plug.
