Import Air Hose Connect Plastic Coupler — Buy in wholesale FOB from Supplier in China

This air hose connect plastic coupler is a quick-connect pneumatic fitting manufactured by Chaoran Plastic Co., Ltd. in Shandong Province, China. The body is injection-moulded from two specified thermoplastics, nylon (PA) and polyurethane (PU), with a round head code and equal shape configuration. Thread options cover NPT, BSPT, PT and BSPP standards across sizes from 1/8 inch to 1/2 inch, and the coupler is rated for working pressures of 1-10 bar and temperatures from -20°C to +60°C.

Nylon PA66 and PU are standard choices in pneumatic quick-coupling manufacture because they combine chemical resistance with sufficient elasticity for repeated connect-disconnect cycles. The injection-moulding process ensures consistent wall thickness and thread accuracy, which is critical for leak-free operation in compressed air systems. Typical industry practice for this class of coupler includes black colour coding to denote general-purpose air service, and the straight union form allows inline hose-to-hose connection without flow-direction change.

Buyers are typically industrial distributors, automotive repair equipment suppliers, and OEMs of pneumatic tools or compressed-air systems. The coupler is suitable for water, gas and oil media within the stated pressure-temperature envelope. For volume procurement from Chaoran Plastic Co., Ltd., confirm thread specification, material grade (PA or PU), and whether the supplier holds batch test records for burst pressure and thread dimensional tolerance.

Chaoran Plastic Co., Ltd. is located at No. 7 Building, Guoda International Trading Center, Dingtao Town, Shandong Province, China, postal code 274100.
