Asked about the Z-RAM 0.2 L air bottle's thread and its height without a regulator, Z-RAM specified 5/8-18 UNF and 18 cm. Those figures are the product-specific support answer for the bottle being discussed—not the height of a complete bottle-and-regulator unit or a universal specification for every 0.2 L tank.
“Without the regulator” changes what is being measured
The original question expressly separated the bare bottle from its regulator. That qualifier matters: the bottle body and the complete regulated unit are different objects. A bare-bottle height cannot simply be used as the overall size of a system with a regulator attached.
The current bottle-only offer makes the component boundary clear. It lists one 0.2 L HPA bottle and says that the regulator is not included. Its description does not publish an overall height for a complete regulated assembly. Keep the support answer's 18 cm within its stated bare-bottle scope.
The thread answer also belongs to an exact component
The 5/8-18 UNF answer followed the question about the bottle itself. It should not be reassigned to an air-line port, an external adapter or a marker-side connection merely because those parts appear in the same air system.
Nor does a volume or pressure label establish a universal thread standard. “0.2 L” identifies volume; it does not specify every outside dimension or connection. Use the exact bottle and matching component specifications when checking an interface, rather than inferring it from a familiar capacity or pressure number.
Compare the bare bottle with the complete offer
The separately listed 0.2 L system with an 800 PSI preset regulator includes both the bottle and the regulator. It is a useful comparison because it changes the boundary of the item being described. The current listing does not provide an overall length that would justify calling that complete unit 18 cm tall.
The two cards below identify these different delivery scopes; they are not an instruction to combine or modify pressure components. Z-RAM's earlier figures refer to the bottle without a regulator; the separate regulated offer includes both components. For a purchase that depends on precise clearance or connection dimensions, confirm the exact current bottle version rather than extending that earlier answer to every similar-looking tank.
Bare bottle versus complete regulated unit

0.2 LITER HP Bottle ASA Air Tank 200 BAR / 3000 PSI
The current bottle-only 0.2 L HPA offer; no regulator is included. Z-RAM's earlier 18 cm height figure refers to the bottle without a regulator, not the complete regulated unit.

0.2 LITER HP Bottle ASA Air Tank 200 BAR / 3000 PSI with 800 PSI Regulator
A 0.2 L bottle supplied with an 800 PSI preset regulator. This is a complete regulated product, so the bare-bottle height is not its stated overall dimension.
