Ready to Ship
Ready to ShipA hex bushing is a fitting which has different threads on opposite ends, where one end is referred to as a male thread and the other end as a female thread. Hex bushings are mainly used to reduce or change the thread of a pipe. Hexagonal bushings come in various materials including brass.
In addition, hexagonal bushings come in various types, including:
Straight Brass Hexagonal Bushings
Straight brass bushings are cylindrical sleeves with the same inner diameter on both sides. They are mainly used to connect two identical sized shafts and transmit power from one to the other. This type of bushing is preferred because of its ease of installation and ability to reduce wear by acting as a buffer between rotating parts.
Offset Brass Hexagonal Bushings
Offset brass bushings have their sleeves in an off-set position from each other. This type of bushing is used to make the connection slightly off center so that even though the shafts are aligned, the two are offset from each other. This type of bushing is people’s favorite when they want to shift the load distribution to a different area or compensate for a misalignment.
Brass Hexagonal Bushings with Set Screws
Brass hex bushings with set screws are small screws used to fix a bushing or sleeve in place. These set screws tighten against the shaft to avoid any movement. Set screw bushings are used where extra hold is needed. This could be on a vertical shaft or where there is a heavy load in one direction.
Brass Hexagonal Sleeves
Hexagonal brass sleeves are used to connect two shafts, either the same or of different diameters, to drive together. They are used for coupling purposes only. Hexagonal sleeves do not have any internal threads like bushings. They also do not have any practical fit like bushings. Their only use is to couple two shafts together. Hexagonal sleeves are made of brass, which is a durable, corrosion resistant material that provides a good grip on the shafts.
Brass Hexagonal Bushings
Brass hex bushings are internal pipe thread to external machine screw or metric screw. They are primarily used to adapt a threaded pipe to a male fitting. Hex bushings provide a means of reducing the size of a pipe or changing its direction while absorbing shocks, vibrations, and misalignment.
Copper Zinc Alloy
Brass is primarily an alloy of copper and zinc. The proportion of each metal depends on the brass variety. For instance, red brass contains a higher ratio of copper for strength, while yellow brass has a higher ratio of zinc for easier machining.
The two metals offer complementary benefits to the resulting alloy. Copper provides corrosion resistance, machinability, and antimicrobial properties, while zinc improves the metals’ strength and hardness.
Copper Tin Antimicrobial Brass
Copper tin antimicrobial brass contains a small percentage of nickel and lead. This variety has approximately 90% copper, 5% tin, 3% nickel, and 2% zinc. It is primarily used for plumbing fixtures, doorknobs, and handles, which capitalize on the 90% copper content for its antimicrobial properties.
The combination of copper, tin, and other metals offers the alloy superior strength, corrosion resistance, and antimicrobial properties.
Copper Zinc Lead
Copper zinc lead brass has about 86% copper, 3% zinc, 7% lead, and 4% nickel. The addition of lead enhances machinability, allowing the creation of more complex and precise components.
This variety is also highly corrosion resistant. It is often used for components that require high wear resistance such as the manufacture of marine fittings and fasteners, which are exposed to harsh environments.
Copper Zinc Silicon
Copper zinc silicon brass contains about 80% copper, 4% silicon, 15% zinc, and 1% iron. Silicon improves zinc’s corrosion resistance properties while copper and zinc enhance the alloy’s strength and workability.
Silicon bronze, a variety of this brass, substitutes nickel and lead for small amounts of iron. Iron helps the alloy maintain its shape and improve magnetic properties, making it ideal for electrical and electronic applications.
Copper Zinc Iron
Copper zinc iron has 79% copper, 21% zinc, and a varying proportion of iron. The addition of iron enhances the strength and hardness of the alloy. It makes it more suitable for precision components in mechanical systems.
Like the previous varieties, this one also enhances corrosion resistance. The increased iron content reduces copper’s magnetic shielding, making it unsuitable for anti-magnetic applications.
Natural Corrosion Resistance
Brass is primarily an alloy of copper. Copper has natural corrosion resistance that is highly valued in marine and plumbing applications. What does a hexagonal bushing do? The corrosion resistance allows brass hex bushings to withstand harsh environments. These include moisture, salt air, and chemical exposure. This makes them ideal for outdoor use and marine industries.
Durability and Strength
Brass is durable and strong. It allows hex bushings to resist frequent mechanical stresses such as friction, wear, and fatigue. This durability ensures the long-term performance of brass hex bushings in various applications.
Thermal and Electric Conductor
Copper, an essential component of brass, provides excellent thermal and electrical conductivity. Brass hex bushings can be used in electrical applications such as connectors, where efficient heat dissipation and electrical conduction are required.
Automotive and Machinery
Brass hex bushings are popularly used in the automotive industry. -Because of their durability, corrosion resistance, and excellent thermal and electrical conductivity. They are installed in machines, including coupling components in motors and gear systems.
Brass hex bushings are also used in precision mechanical parts such as gears and shafts. The bushings reduce wear and tear by acting as a buffer between the two interacting materials. They ensure the machines have a longer lifespan.
Hydraulic and Pneumatic Systems
Brass hex bushings are widely applied in hydraulic and pneumatic systems to connect pipes and components. By virtue of their corrosion resistance and ability to withstand pressure, they are ideal for such systems. They ensure long-term reliability in the transfer of fluids and gases.
Construction and Marine Industries
Brass hexagonal bushing uses are common in the construction and marine industries. Common examples include marine hardware, shipbuilding, and offshore structures. In these applications, the bushings offer protection against moisture and salt, which can cause other materials to corrode. This makes them ideal for nautical and coastal environments.
Plumbing Systems
Brass bushings for plumbing are common in plumbing systems due to their ability to resist corrosion and chemical reactions with water. Therefore, brass hex bushings serve as reliable adapters between pipes. This ensures effective and leak-free connections.
Electrical and Electronic Applications
Brass hexagonal bushings are also used as insulation in electronic devices. Since brass is a good conductor, the bushings can also be used in connectors and terminals for efficient electrical transmission. Their resistance to corrosion also helps maintain long-term electrical connections.
Industrial and Commercial Equipment
Brass hex bushings are commonly applied in pumps, valves, and other industrial machinery in the commercial sector. The durability of these bushing, as well as their ability to resist wear and corrosion, ensures reliability and longevity for various equipment.
When choosing a brass hex bushing, several key factor come into play. These factors ensure compatibility and functionality according to the intended application. Here are the most notable considerations:
Sustainability
As mentioned earlier, sustainability is a key consideration for any product in today’s market. In today’s environmentally-conscious world, it is recommended to source brass from responsible manufacturers who minimize their carbon emissions and have effective waste management practices.
