The GeekVape Z Subohm Tank 5 utilizes a push-to-fill top cap and a specialized press-fit coil system to maintain its legendary leak-proof status. This tank is designed with a top-to-bottom airflow path that requires the notched “Z Series” coil structure to align perfectly with the internal chimney for optimal vapor production. While the GeekVape Z Subohm Tank 5 is compatible with the entire Z-coil line, it is most effective when used with the upgraded XM “Boost” versions, which feature a denser mesh weave to handle the increased 5.5ml juice capacity with up to double the lifespan of standard coils.

What Other Coils Work
-
Z Fli & Z SE Tanks: The Z Subohm Tank 5 shares its entire coil ecosystem with the Z Fli and Z SE series, making all Z-branded mesh coils fully interchangeable across these platforms.
-
L200 (Aegis Legend 2) & Aegis Solo 3 Kits: If you are using the tank included in these kits, it utilizes the same Z-coil architecture found in the standalone Tank 5.
-
Z Max Tank: These are incompatible; the Z Max uses “M Series” coils which are significantly larger and will not fit the Z Subohm Tank 5.
Z Subohm Tank 5: Don’t Buy These Coils
⚠️”Supermesh” or “B Series” coils are not compatible. While they are also made by GeekVape, they are significantly smaller and will not seal in the Z-series housing.
