The pack contains 6 identical 28 mm black T-shape diffuser caps made of plastic. The T-shape widens outwards at the top, so a flat, round disc-like upper surface attaches to the bottle neck. The set is made for the 28 mm neck bottles of the RDBot-21..32 series.
What the 6-piece cap set is for
The caps are used to close the neck of the bottle and to provide a decorative finish. The T-shape gives a contrasting, modern effect: the black colour highlights the bottle glass, whether it is amber or clear. The pack of 6 is practical when a unified, black-capped diffuser set is wanted, or when caps on existing bottles need to be replaced.
Material and finish
The base material is durable, dimensionally stable black plastic with a slightly satin finish. The T-shape widening sits stably on the bottle neck and provides a comfortable grip when the cap is taken off and on regularly (for example, when changing reeds in a diffuser). The surface is easy to clean and does not rust.
Compatibility
- RDBot-21 .. RDBot-32 series diffuser bottles with a 28 mm neck
- Compatible models in the RDBot-11 .. RDBot-16 series
- Other bottles with a standard 28 mm outer neck diameter
Cleaning and care
The cap surface can be wiped with a soft, dry or slightly damp cloth. Avoid strong solvents (such as acetone) and abrasive cleaners, as these can scratch or matte the plastic surface. Putting the cap in a dishwasher is also not recommended, so that the black colour stays even over a long period.
Storage and durability
Store the caps in a dry, cool place, protected from direct sunlight. Long-term UV exposure can gradually fade the colour of the black plastic, so a closed box or drawer is the most suitable storage. With appropriate care, the cap retains its deep black appearance for a long time.
