Compatibility comes first
Similar-looking threads and locking mechanisms are not proof of fit. An incompatible accessory can leak, damage the closure or detach during use. Compare the exact manufacturer article numbers.
Flexible and rigid designs
| Design | Potential advantage | Point to check |
|---|---|---|
| Flexible | reaches recessed filler openings | kinking, support and controlled positioning |
| Rigid | predictable shape | angle, length and clearance |
| Integrated | stored with the can | seal and contamination protection |
Venting and flow
Air must enter as liquid leaves. Depending on the design, venting is integrated or controlled through the closure system. Do not add holes or modify the can. Follow the manufacturer instructions and stop if the flow becomes uncontrolled.
Before buying
- Exact can and spout article numbers match.
- Seal and cap arrangement are included or clearly specified.
- Length and angle fit the receiving opening.
- The accessory is intended for the actual fuel.
- Replacement seals and caps are available.
- The spout can be stored cleanly and protected from damage.
Frequently asked questions
Is every spout compatible with every can?
No. Threads, locking systems, seals and venting differ. Use the manufacturer-specified accessory for the exact can.
Is a flexible spout always better?
Not always. It may improve access, while a rigid design can provide different control. Fit, flow, venting and the receiving opening matter.
Can a damaged spout be repaired with tape?
An improvised repair is not an appropriate substitute for a compatible undamaged fuel accessory. Replace the affected part according to the manufacturer instructions.
