About Us

Two decades making pneumatic couplings and fittings in Ningbo, China.

Our Story

A focused workshop in Ningbo since 2005

Established on 1 March 2005 in Shitang Village, Gaoqiao Town, Haishu District, Ningbo, JIAJIE Pneumatic began as a small workshop making pneumatic quick couplers. More than twenty years on, we still concentrate on that same craft: the machined parts that keep compressed-air systems connected and running.

We are a focused 15-person factory with in-house turning, assembly and inspection — not a trading company and not a giant plant. That is deliberate. It lets us take on trial runs and mixed orders that larger factories decline, answer enquiries the same day, and ship samples in days rather than weeks. Being roughly 40 km from the Port of Ningbo keeps export shipping fast and economical.
