D.O.T Air Brake Nylon Tubing Fitting Industry Knowledge Analysis - Focus on Legines Industrial Machinery Inc.
D.O.T Air Brake Nylon Tubing Fittings are connectors designed for vehicle air brake systems and are used to connect nylon brake tubings to various brake components. Its core task is to ensure the safe transmission of high-pressure air in the brake system to avoid leakage, breakage or loosening. Qualified D.O.T air brake fittings must comply with multiple North American and international industry standards, such as FMVSS 571.106, CMVSS 106, SAE J246, SAE J1131, SAE J1402, etc. These standards have strict requirements on the material, pressure resistance, sealing, seismic resistance and long-term stability of the fittings.
The air brake nylon tubing fittings produced by Legines have passed FMVSS571.106, CMVSS 106 and SAE J1402 certifications to ensure the reliable performance of the products in various harsh application environments.
Legines' connectors are mainly made of high-strength brass and stainless steel. CA360 is a high-performance brass alloy containing zinc. It is often used to manufacture connectors that require high precision and strength. It shows strong oxidation resistance and corrosion resistance in industrial environments such as moisture, oil, acid, alkali and salt spray, which greatly extends the service life of the connector. It is especially suitable for scenes such as automobile chassis and air brake systems that are exposed to rain and salt spray. Compared with brass, stainless steel has stronger corrosion resistance and is particularly suitable for high temperature, high humidity, high acid and alkali environments. 316 stainless steel contains molybdenum, which performs particularly well in chemical, marine and highly corrosive applications.
In air brake and pneumatic systems, tubings and connectors are often exposed to the outdoors or complex environments. Corrosion may cause the connectors to loosen, leak or even brake failure. The use of highly corrosion-resistant materials can significantly improve the long-term stability and safety of the system.
Legines has 45 fully automatic CNC machine tools and 35 semi-automatic CNC machining centers, with an annual output of over 2.5 million sets. It has strong processing capabilities and has great advantages in the production of D.O.T air brake nylon tubing fittings. High-precision thread, cone and sealing surface processing ensures that the fittings are burr-free and misaligned when connected to nylon tubings or metal tubings, improves air tightness, and effectively prevents gas leakage or pressure instability. The precision of all parts is controlled at the micron level to ensure that the size of each fitting is consistent in batch production. It performs more stably in automated assembly lines, reduces manual adjustments, and improves production efficiency. It can be adapted to various types of tubings to meet different international market standards.
The temperature adaptability of the D.O.T air brake nylon tubing fittings produced by Legines is from -40°F to +200°F (-40℃ to +93℃) and can operate reliably in extremely cold climates or high-temperature areas. The fitting material will not loosen or crack due to thermal expansion and contraction near the car engine or in high-temperature industrial equipment. The maximum working pressure can reach 150 psi, which meets the working requirements of most commercial vehicle air brake systems. Even in the case of pneumatic shock or pressure fluctuation, the joint can maintain structural stability and good sealing.
D.O.T air brake nylon tubing joints are widely used in the air brake systems of commercial vehicles such as heavy trucks, trailers, school buses, etc.; pneumatic systems of industrial vehicles such as forklifts, sweepers, and cranes; air control systems that require high air tightness and shock resistance, as well as its excellent shock resistance and stable sealing structure, ensure continuous work in high-intensity, high-load, and high-frequency operating environments.
Legines not only provides standard specifications of air brake joints, but also provides on-demand customization services. The size, structure, thread type (NPT, BSP, METRIC, etc.), special materials (such as stainless steel 304/316), etc. can be customized according to the technical parameters or drawings provided by the customer to meet the differentiated needs of different markets around the world.
