Description
Overview:
This tank cap holder is a genuine Husqvarna OEM retainer for securing the fuel tank cap to the machine. Made from a tough, flexible polymer in black, it keeps the cap attached to the body so it cannot be misplaced during refuelling or maintenance. The holder helps maintain fuel system integrity by ensuring the cap is always available to be tightened correctly after filling. It is designed for Husqvarna petrol and battery equipment across chainsaws and power cutters, with direct fitment on popular models such as the K760 and 135. Built for regular site use, it offers a straightforward replacement for worn or broken retainers and supports safe, efficient operation.
Key Features:
- Genuine Husqvarna OEM part for correct fit and performance
- Securely retains the fuel tank cap to prevent loss on site
- Durable, flexible polymer resists fuel, oil, vibration and weather
- Maintains fuel system integrity by keeping the original cap with the machine
- Simple, tool-light installation on compatible Husqvarna models
- Black, low-profile design avoids snagging and keeps controls clear
- Suitable for heavy-duty use on saws and cutters in tough conditions
- Helps reduce downtime and replacement cap costs
Typical Applications:
Used on chainsaws and cut-off saws in construction, landscaping, forestry and emergency services. Ideal where frequent refuelling occurs and there is a risk of caps being dropped or lost, such as demolition sites, roadside work, arborist tasks, and yard operations. Helps keep equipment ready for use and reduces interruptions during cutting, trimming, and rescue cutting.
Also known as:
Fuel cap tether, cap strap, cap keeper, cap lanyard, tank lid tether. These common terms refer to the same retaining device that secures a machine's fuel cap to the tank or body to avoid misplacement.
