Pneumatic component equivalents — Chinese alternatives to SMC, Festo & Parker.

Cylinders, valves, and air preparation, cross-referenced to verified Chinese equivalents (AirTAC, SNS, STNC) — with the exact spec differences and a verdict: drop-in, needs changes, or depends on your application.

The problem this solves

The hard part isn’t finding an alternative. It’s knowing where it doesn’t fit.

If you run SMC, Festo, or Parker pneumatics and want a lower-cost Chinese equivalent, the risk is never the catalog — it’s the unstated differences. Many pneumatic parts share ISO interface dimensions, so the body and mounting often match exactly. The differences that matter are usually the port thread (G vs NPT), the seal compound for your medium, and the pressure or cycle-life rating. We show those deltas and cite the source for every spec. When we can’t verify a match, we say so.

Common questions

Pneumatic equivalents — FAQ

Is there a Chinese equivalent to SMC pneumatic cylinders?

Yes — AirTAC, SNS, and STNC make cylinders that share ISO 15552/6432 interface dimensions with many SMC series. The lookup shows the exact spec deltas for your part.

Are AirTAC cylinders a direct drop-in for SMC?

Often on dimensions — but check the port thread (G vs NPT), the seal for your medium, and the pressure rating. Each match is classified as a drop-in or an equivalent-with-changes.

How do I find the equivalent for my part number?

Enter it in the lookup above. While the automated tool is in build, we run the cross-reference by hand against the same verification standard and reply by email.
