SUN PROJECT 4mm Connector Plug No. 2 SP-34-2 for Marui/Maruzen etc.

This external carbon dioxide (CO2) power system has a lower environmental impact than standard refrigerant gas. Its pressure changes little with temperature, maintaining stable power even in low-temperature environments or when the temperature drops due to rapid fire. It's also the most compact external-source system available. Due to its characteristics, it's a popular system in the speed shooting world, and with the increase in tatami room shooters due to the stay-at-home lifestyle, it's now experiencing a quiet boom.

This connector plug is specifically designed for use with 4mm hoses for Sun Project Green Gas Systems/external power sources. It minimizes flow reduction and ensures a more stable power supply.

If you have a 4mm coupler (socket), you can add it here.

Connector plug compatible: Tokyo Marui, Maruzen gas guns, etc.

Compatible with M4.5 pitch 0.5 screw diameter.

The air stop function is built in. When you remove the coupler from the plug (threaded part), the air flow stops.

A dedicated coupler (socket) is required for use. (Compatible couplers (sockets) are SP-33, SP-25-4, and SP-27-4.)

*Not compatible with SP-23, SP-25-6, and SP-27-6 couplers.
*Not compatible with SP-23 and SP-24 coupler/connector plugs.
