Pneumatic Fittings Manufacturer in China — Ningbo Factory Since 2005

CNC-machined pneumatic fittings and manifolds from our Ningbo workshop: stainless, brass and steel, with OEM/ODM for overseas distributors and importers.

What We Make

About the Factory

A focused workshop, not a trading company

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. That 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.
