Meckorn 18" Chainsaw Chain 4-Pack .325" Pitch .050" Gauge 72DL — Semi-Chisel X-Cut SP33G for Husqvarna/Echo/Stihl

Meckorn's 4-pack of 18-inch .325" pitch, .050" gauge chains with 72 drive links are replacement semi-chisel chains designed to fit Husqvarna, Echo, Stihl-compatible bars and many Oregon models.

These chains are sold as a set of four identical X-Cut SP33G 18-inch chains, sized .325" pitch, .050" gauge with 72 drive links. Built to replace common OEM numbers from Oregon, Husqvarna and Stihl, the pack is intended for homeowners and pros who need multiple spare chains for tasks like firewood cutting, property maintenance and jobsite backups. They use a semi-chisel tooth profile for balanced cutting speed and easier maintenance than full-chisel alternatives.

Will this chain fit my chainsaw and bar?

Compatibility depends on three measurements: bar length, pitch and gauge, plus the number of drive links. If your saw requires an 18" bar with .325" pitch and .050" gauge and the bar takes 72 drive links, these chains will fit.

• Confirm your bar length equals 18 inches (measure tip-to-mount).
• Verify pitch is .325" and gauge is .050" on your bar or existing chain.
• Check the drive link count is 72; if unsure, count links on your chain.

How do these chains compare to original equipment (OEM)?

These Meckorn chains are engineered to match common OEM specifications so they can replace Oregon H72 / M72 / Q72 and several Husqvarna and Stihl references. They use a semi-chisel tooth design for reliable cutting with less frequent sharpening than a full-chisel tooth.

• Meets .325" pitch and .050" gauge OEM tolerances for a direct replacement.
• Identified as X-Cut SP33G 72DL to match listed part numbers.
• Semi-chisel cutters balance cutting speed with durability and easier sharpening.

• Can substitute for Oregon H72-type chains and some Stihl 23RM3/23RS3 72-link references when specs match.

What should I know about installation and maintenance?

Installing a chainsaw chain requires basic tools and safety steps: bar nuts loosened, proper tension applied, and routine lubrication. Regularly check tension, keep the chain sharp and maintain the bar and sprocket for longest life.

• Fit the chain on the bar with the cutter teeth facing forward at the top of the bar.
• Tension the chain so it snaps back into place but still turns freely by hand.
• Use bar oil during operation and sharpen cutters as needed to preserve cutting efficiency.

Who is this for? This Meckorn 4-pack is suited to homeowners, land managers and small contractors who want multiple ready-to-install replacement chains for 18" bars. It’s practical for anyone who runs compatible Husqvarna, Echo or Stihl-style saws and needs a cost-effective supply of semi-chisel chains for routine cutting, seasonal pruning and on-site spare parts. If you're unsure about fit, measure your bar pitch, gauge and drive link count or contact after-sales support for help matching your saw specifications.
