Dab domes
Domes is a category of DAB domes, covers, and component sets, including parts intended for configurations used with oils or waxes.
List of products
Components in this group are not one universal accessory type. They may act as a dome or cover, take the form of a cap, or belong to a set with a nail. They differ in construction and connection size, so their role depends on the specific version's design and the setup in which it will operate.
What role does a DAB dome serve?
A dome, also referred to as a chimney or cover, is a component used in certain DAB designs. Its role depends on the complete set: it may cover a connected component and form part of the path that directs air and the vapor produced. Not every DAB setup uses the same solution, however, so product names alone do not mean parts are interchangeable between different designs.
This group includes individual domes and caps as well as component sets. The current selection includes a DAB dome or chimney, a DAB component set, FOUR TWENTY Oil Bowl 18.8 mm, GRACE GLASS LIMITED Oil Cap 18.8 mm, FOUR TWENTY Dome with Nail 18.8 mm, and a Dome for Oil or Wax 14.5 mm, among other items.
Actual construction versions
An individual dome or cap is intended to complete an appropriate configuration, while a set with a nail supplies matching parts together. An oil bowl is another component version within the same group. These subtypes may look similar but differ in role and how they connect to other parts.
Connection diameter also matters. Product names in this category include 14.5 mm and 18.8 mm sizes. The measurement describes an important point of mechanical fit, but does not alone establish full compatibility: component type, joint geometry, and the construction of connected parts also count.

Matching and maintaining components
When combining parts, distinguish an individual cover from a set and maintain compatible connection sizes. A 14.5 mm component is not equivalent to an 18.8 mm version, and matching diameters do not replace structural compatibility. The most reliable basis is the subtype name and the way the part is intended to work with the rest of the set.
Regular removal of buildup helps keep the airflow clear and handling convenient. Allow the component to cool completely before cleaning, and use a method and cleaning agent suitable for its material. Handling connections gently reduces the risk of damage when taking the setup apart.

Frequently Asked Questions
Does a 14.5 mm dome fit an 18.8 mm connection?
No, these are different connection sizes. A proper fit requires a matching diameter and the correct type and geometry of connected parts.
How does a dome differ from a set with a nail?
A dome is a single cover, while a set with a nail includes at least two components intended for a shared configuration.
