Pneumatic component equivalents — China-manufactured alternatives to SMC, Festo & Parker.

Cylinders, valves, and air preparation, cross-referenced to China-manufactured 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 China-manufactured 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 and duty rating. We show those differences 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's SAI series shares ISO 15552 interface dimensions with SMC's C96 profile cylinders, verified against both catalogs. SNS and STNC equivalents are in production. Each match shows the exact spec differences 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.
