About the Factory

Two decades on one craft

JIAJIE Pneumatic began in 2005 in Shitang Village, Gaoqiao Town, Haishu District, Ningbo, as a small workshop making pneumatic quick couplers. We are still a focused 15-person factory with in-house turning, assembly and inspection.

That focus lets us take trial runs and mixed orders that larger factories decline, answer enquiries the same day, and ship samples in days rather than weeks.
