Ryobi R18PPS130 Chain Questions

What size chain does a Ryobi R18PPS130 take?

3/8" LP pitch, .043" (1.1mm) gauge, 33 drive links on the 8" (203mm) bar.

Will this fit other Ryobi 8" models?

The same 33 drive link, 3/8" LP .043" chain is used across much of Ryobi's 8" range, including the R18PPSA20 pole pruner attachment. Confirm your own bar stamp before ordering, or use our Search by Chainsaw tool.

What file do I use on this chain?

A 4.0mm (5/32") round file suits this 3/8" LP chain.

Is this a genuine Ryobi chain?

No — it's an Alpine Chain Co. chain manufactured to the same specification, matching the Oregon 90PX / R33. Same pitch, gauge and drive link count, 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 Ryobi R18PPS130, 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.
