Hipa 20" Chainsaw Chain 3-Pack for Echo CS-590 — 3/8" Pitch .050" Gauge, 70-DL Full-Chisel, Pre-Oiled

Hipa 3PCS 20" replacement chains are 3/8" pitch, .050" gauge, 70 drive-link full-chisel chains designed to fit Echo CS-590 and compatible saws.

These three pre-coated replacement chains deliver a ready-to-install option for timber work and heavy-duty cutting when you need a reliable spare or an immediate swap. The set includes chains engineered with perforated plates to improve heat dissipation and reduce wear, a factory-applied protective oil coating to resist rust, and rivets that are heat-treated for better durability. Dimensions and drive-link count match common Echo models and several Poulan saws, making this a practical fit-for-purpose choice.

Will these chains fit my Echo CS-590 or Poulan saw?

Yes — the chains are sized to match 20" guide bars with a 3/8" pitch and .050" gauge, and they include 70 drive links to align with the specified sprocket and bar length. You should confirm your saw’s pitch, gauge, and required drive-link count before installing.

• Fits Echo CS-590 TIMBER WOLF and CS-4400 models
• Compatible with Poulan PR5020 and similar 20" setups
• Replaces OEM part number 72LPX70CQ
• Check bar groove width and sprocket teeth to confirm compatibility

How does the perforated design affect chain performance?

The perforated drive and reverse plates create air channels that reduce heat buildup and friction at the pin-and-plate junctions. Reduced operating temperature slows material softening and wear, which helps maintain cutting consistency and extends service intervals.

• Improves airflow around pins and plates for cooler operation
• Decreases friction and slows plate wear under heavy loads
• Supports longer-lasting chain geometry and cutting sharpness
• Beneficial for prolonged cutting sessions or dry conditions

What protection and durability features are built into these chains?

Each chain is coated with a protective oil layer at the factory to guard against rust and surface corrosion during storage and initial use. Rivets receive heat treatment and quenching to increase strength and resistance to breakage, so the chains are ready to install straight from the package.

• Surface-coated protective oil reduces corrosion risk
• Heat-treated, quenched rivets for improved tensile reliability
• Full-chisel cutters for aggressive, efficient cutting action
• Prepared for immediate mounting without extra pre-treatment

How should I maintain these chains for best life and safety?

Routine sharpening, correct tensioning, and consistent lubrication will maximize life and preserve cutting performance. Inspect the chain frequently for pin wear, broken cutters, and proper fit, and replace the chain if damaged or stretched beyond safe limits.

• Keep chain tension within manufacturer’s recommended range
• Sharpen cutters or use a qualified sharpener when dull
• Use quality bar and chain oil during operation
• Replace chain if rivets loosen or cutting performance degrades

Who is this for: This 3-pack is aimed at professional arborists, landscapers, and serious homeowners who run 20" Echo or compatible chainsaws and want immediate spares or replacements that balance cutting power and durability. If you need full-chisel performance, reduced thermal wear, and ready-to-use chains with OEM-equivalent sizing, this set provides a cost-effective solution for busy workdays and longer cutting tasks.
