Product Details

Hünersdorff Poly Tank Custom Vent Cap
Cap only for sale.

*This is the product shown in the second image.

This solves the problem of fuel dispensing from outdoor containers where the lack of an air vent causes it to sputter out (glug... glug... WHOOSH!).

Use an 8mm drill bit for the installation hole (7.5mm is too tight).
Thread kite string through as shown in the photo to install (wire can also be used).

This is an air vent cap for customizing fuel cans and poly tanks such as Hünersdorff. It does not come with the plastic tether to prevent loss. (This is not an authentic Hünersdorff product.)

I am selling this because I intended to buy only one, but it came in a multi-pack.

As this is a used item, please refrain from purchasing if you are sensitive about condition.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
