The FLD037 is a compact 4ml disposable vape hardware platform developed for OEM, ODM and private-label product programs.
It features a 4.0ml tank capacity, a 1.4Ω resistance and a constant output of 3.7V ± 0.1V. This configuration is designed to provide controlled heating performance when matched with a compatible oil formulation.
The device incorporates a 4 × 2.0mm oil-intake configuration to support stable oil flow and consistent heating-system saturation. Final compatibility should be verified through filling, soaking, leakage, clogging and vapor-performance testing before mass production.
Powered by a 350mAh battery, the FLD037 measures 82.5 × 38.5 × 16mm and weighs 31.5g. Its compact rectangular body provides a portable format suitable for customized 4ml disposable hardware programs.
Custom logo printing, device colors, surface finishes and retail packaging are available for OEM and ODM projects.
