D.O.T TRANSMISSION FITTINGS Manufacturers

D.O.T Transmission Fittings are high-performance connection accessories designed for pneumatic transmission systems. They are widely used in shift control modules for heavy trucks, buses, construction machinery and other vehicles. These connectors are usually made of CA360 brass or 304/316 stainless steel, with excellent corrosion resistance and pressure resistance, and can maintain reliable connections under high pressure, high vibration and extreme climate conditions. Its structure includes standard American thread (NPT), quick-connect connection, compression locking system and other types. It is compatible with nylon tubes and copper tubes for quick installation and maintenance. The product is certified by North American regulations such as FMVSS 571.106, CMVSS 106 and SAE J1402 to ensure compliance with safety specifications for vehicle air brake and pneumatic systems. Its operating temperature range is -40°F to +200°F, and the maximum working pressure is 150 psi, which can adapt to various harsh industrial environments. With high sealing, high stability and long life, D.O.T Transmission Fittings are essential key components for achieving pneumatic shifting with sensitive response and precise control.

Legines has full CNC processing to ensure high precision and complete precision manufacturing equipment. Each transmission joint has high consistency and precision, effectively avoiding safety hazards such as air leakage and loosening, and is particularly suitable for the application of automated assembly lines and high-demand systems. Legines uses industrial-grade raw materials such as CA360 high-strength brass and 304/316 stainless steel. The D.O.T Transmission Fittings produced by Legines have strong corrosion resistance and can cope with harsh working conditions such as high humidity and salt spray. They are suitable for coastal and cold regions in North America; they have high strength and impact resistance to adapt to the strong vibration conditions of commercial vehicles under rugged road conditions; they have a wide temperature range of -40°F to +200°F and can withstand extreme cold or high temperature environments. Legines is equipped with three complete sets of testing equipment. Each batch of D.O.T Transmission Fittings produced has undergone air tightness testing, burst testing, thread accuracy and sealing testing to ensure that the product can operate without failure in actual working conditions for a long time.

D.O.T Transmission Fittings can be used in commercial truck and bus transmission systems, and used in automatic pneumatic shift modules to achieve smooth shifting and quick response, effectively improving fuel efficiency and driving experience; used in engineering machinery pneumatic control such as pneumatic shift systems of bulldozers and excavators, maintaining stable connections under high load and dusty environments; used in pneumatic auxiliary systems with air dryers, brake systems, and air conditioning systems to achieve multi-channel air source control and improve system integration.
