Markill Adapter for all puncture-style gas cartridges

This adapter for self-sealing screw top lets you transform a cheaper puncture-style gas cartridge into a valve cartridge. This allows you to use the less expensive puncture-style gas cartridges with gas appliances that are meant only to fit screw top valve cartridges. Three arms secured with a rubber band hold the adapter in place on the cartridge.

Fits with all puncture-style gas cartridges. Screw top fits with Trangia, Markill and Primus stoves and also most other brand stoves.
