Echo Coupler Assembly C510000350 | PAS-225 DPAS-2100 Attachment OEM
Is your attachment slipping, or has the locking wing-nut finally stripped out? The coupler is the heart of the Echo PAS system. This Genuine OEM Echo Coupler Assembly (C510000350) is the factory-original replacement designed to ensure a rock-solid, vibration-free connection between your power head and your attachments.
Don't settle for "universal" clamps that don't align with the Echo Posi-loc™ system. This Authentic Echo part is engineered to maintain perfect driveshaft alignment, preventing the premature wear and stripping of the flexible driveshaft ends that occurs with low-quality aftermarket couplers.
Posi-loc™ Precision: Features the factory-spec spring-loaded locking pin for a secure "click-and-lock" fit every time you swap tools.
Heavy-Duty Clamping Force: Reinforced wing-nut and bolt assembly provide the high-torque grip needed to keep blowers, edgers, and hedge trimmers from rotating during use.
Perfect Internal Alignment: Machined to exact tolerances to ensure the power head driveshaft meets the attachment shaft with zero "play."
Industrial Grade Casting: Built from a high-strength alloy that resists cracking and stripping, even after years of daily attachment changes.
Direct Bolt-On Fit: Includes the housing and all necessary hardware to replace your worn or broken coupler in under 5 minutes.

🛠️ PAS Pro-Tip: A loose coupler ruins driveshafts! Diagnostic Tip: If you notice "metal shavings" inside your coupler or attachment end, your shafts are not fully engaging—replace the coupler before you strip the expensive main driveshaft. Maintenance Tip: Keep the internal coupler clean of grit and old grease. A tiny amount of Echo PowerBlend Grease on the locking pin once a season keeps the "click" smooth. Installation Tip: When installing the C510000350, ensure the alignment hole in the outer pipe is clear. Tighten the mounting bolt first before securing the wing-nut. Pro-Check: Once installed, insert an attachment and give it a firm "twist" test. There should be zero rotation.
This is a Brand New, Genuine OEM ECHO factory part. It is the factory-authorized component required to maintain the professional-grade versatility and safety of your Echo PAS system.
