Will this chain fit other Husqvarna saws?

Possibly, but please use our Search by Chainsaw tool to find your specific saw chain with no doubt.

Is this a genuine Husqvarna chain?

No — it's an Alpine Chain Co. chain manufactured to fit the Husqvarna 525PT5S, replacing the Husqvarna H00 and Oregon 25AP. Same pitch, gauge and drive link options, with a semi-chisel profile chosen for Australian hardwood. Every fit is backed by our Guaranteed Fit system.

How to Verify Your Chain Size

If you are unsure if this is the correct chain for your Husqvarna 525PT5S, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
