Replacement cover cap for the Echo Speed-Feed 375 trimmer head — fits Echo SRM-225 and SRM-230 string trimmers running the older Speed-Feed 375 head
Part Details
- Material: PETG — chosen for its impact resistance and thermal stability over standard PLA
- Quantity: 1 cap (single printed piece)
- Fit: Trimmer head cover cap for the Echo Speed-Feed 375 bump-feed head — replaces the cap only, not the spool or line
- Brand: Unbranded aftermarket replacement
Why This Cap Breaks
The Speed-Feed 375 is a bump-feed head — tapping it on the ground to advance line is exactly what cracks or snaps this cap over time, and years outdoors in UV and heat make the plastic brittle on top of that. Echo kept the SRM-225/SRM-230 model number the same while quietly switching to a new head design, so the exact-fit cap for this older Speed-Feed 375 head is genuinely hard to source — Echo doesn't sell it as a standalone part, and most aftermarket listings bundle it into 3-10 packs sized for bulk buyers rather than a single broken cap.
Compatible Models
Fits: Echo Speed-Feed 375 trimmer head, as used on Echo SRM-225 and SRM-230 string trimmers.
Note: Echo changed the Speed-Feed head design partway through the SRM-225/SRM-230 production run while keeping the same model number, so matching model number alone doesn't guarantee matching head. Please verify fit against your original cap/head before ordering, or message us if you're not sure which head you have.
