How to confirm the fit
- Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g.
3/8" LP .050". - Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
- Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ
What size chain does a Echo PPT-2620H take?
The Echo PPT-2620H runs a 3/8" Low Profile™ pitch, .043" / .050" gauge chain. Available bar lengths: 10", 12", 14". Match the drive-link count to your bar (see the table above).
How do I know which gauge my PPT-2620H chain is?
Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the PPT-2620H are .043" / .050".
Can I put a longer bar on my Echo PPT-2620H?
Oregon lists 10", 12", 14" bars for the PPT-2620H. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
