Part-number accuracy
We check threads, bypass pressures and seating dimensions before quoting, so the part fits on the first attempt.
About us
Compressor parts from people who traded them first
Ningbo Keli-Parts has supplied air compressor spare parts since 2002 - first as a trading service, and since 2006 from our own manufacturing floor in Ningbo, China.
We are a specialized parts supplier for air compressor spare parts, pneumatic, hydraulic and transmission components, serving screw and piston air compressors as well as agricultural and industrial machinery. Our range covers more than 3000 standard parts, and for special working conditions we supply custom parts and sub-assemblies. Our mission is to become the preferred global supplier of ready-to-install, high-quality compressor components and spare parts with competitive pricing for OEMs, distributors and end users worldwide.
Our story
From trading desk to factory floor
Founded in 2002, invested in manufacturing in 2006.
Keli-Parts started in 2002 as a trading service provider, matching compressor users with the parts they needed. Four years of listening to fitting problems, wrong-reference deliveries and urgent downtime orders taught us where the parts trade fails. In 2006 we invested in our own manufacturing company, Ningbo Keli-parts Manufacture Co., Ltd. - today operating alongside Ningbo Keli International Trading Co., Ltd., to control the details that decide fit and life: dimensions, media, threads and tolerances. Today we combine the sourcing reach of a trader and the production control of a manufacturer. Today the same catalog runs from complete screw compressor units down to the consumables that keep them running.

How we work
The standards behind every quotation.
These principles keep the parts trade honest: verifiable specifications, honest fitment answers, and orders sized to your business.
02
Small orders, fast response
Trial orders and mixed batches are welcome. Consumable parts are built for repeat business, not one-off deals.
03
Quality you can verify
Specifications are stated as measurable numbers - oil carry-over in ppm, pressure differential in bar - not as adjectives.
04
Custom capability
Beyond the 3000+ standard parts, we make custom parts and sub-assemblies for special working conditions and applications.
