Pneumatic fittings are mostly used to connect pneumatic air brake circuits for industrial and commercial vehicles. Pneumatic fittings are characterized by low pressure requirements and tight ness, light weight and compact, easy installation and cost-effectiveness.

Standards are aimed at the defects and deficiencies of the prior art, and provide a pneumatic quick coupling with convenient and quick operation and low gas pressure loss.

The pneumatic quick coupling is a special connecting device that can quickly connect or disconnect the gas pipeline and realize quick disassembly and assembly of the pipeline.

Standards has in cooperation with leading commercial vehicle manufacturers, developed and produced an air coupling system based on composite material and brass.
