About this product
Blue Sea Systems replacement cap for panel-mount AGC/MDL fuse holder PN 5021. Component part, not a complete holder. Manufacturer PN 5022.
This is the replacement cap for Blue Sea Systems' panel-mount AGC/MDL fuse holder (PN 5021) — a single small component, not a complete fuse holder. If a fuse holder's cap has cracked, gone missing, or lost its watertight seal, this part lets you replace just the cap rather than the entire holder.
Key details
- Replaces the cap on Blue Sea PN 5021 fuse holders
- Ships already included with every new 5021 holder — order this separately only when replacing a worn or lost cap
- No other published specifications beyond weight
Double-check your part before ordering: if what actually needs replacing is the whole waterproof fuse holder body, order PN 5021 instead — this listing is the cap component only, and won't function as a standalone fuse holder.
