The Smart Gas blend contains a high quantity of silicone oil, which lubricates and protects the seals and internal mechanisms during every firing cycle, without requiring additional maintenance at each refill.\u003c\/p\u003e\u003cp\u003eThe canister pressure is calibrated to avoid stressing the valves of airsoft magazines, including those with more delicate seals. The plastic nozzle reduces the risk of damaging the fill pin during top-up: a detail that makes a difference on frequently used GBB magazines, where metal nozzles can scratch or deform the pins over time.\u003c\/p\u003e\u003cp\u003eThe Smart Gas formula maintains acceptable performance even at low temperatures, lubricating the internal mechanisms even when the gas would otherwise lose pressure. This is a practical advantage for outdoor sessions in cold weather, where a standard gas can leave the airsoft gun inconsistent even at moderate temperatures. The canister is not refillable: once empty, it must be disposed of in accordance with local regulations for pressurised containers.\u003c\/p\u003e\u003ch2\u003eKey Points\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe high silicone oil content in the blend lubricates the seals with every refill, reducing wear over time without separate maintenance.\u003c\/li\u003e\n\u003cli\u003eThe plastic nozzle protects GBB magazine fill pins from scratches and deformation caused by repeated contact with metal nozzles.\u003c\/li\u003e\n\u003cli\u003eThe optimised pressure is compatible with free-flow gas airsoft guns without risk of over-pressurising the valves.\u003c\/li\u003e\n\u003cli\u003eThe formula maintains operational performance even at low temperatures, useful for outdoor sessions in cold conditions.\u003c\/li\u003e\n\u003cli\u003eThe \u003cstrong\u003e202 mm\u003c\/strong\u003e metal canister is compact and easy to carry in the field.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIn the Box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 ProTech Smart Gas canister 400 ml with plastic nozzle\u003c\/li\u003e\u003c\/ul\u003e","brand":"ProTech Guns","offers":[{"title":"Default Title","offer_id":63798963274058,"sku":"PTECH-400-520","price":5.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0026\/3920\/0291\/files\/30015.jpg?v=1791148540","url":"https:\/\/www.vipertactical.fr\/en\/products\/green-gas-protech-guns-smart-gas-750-ml-black-1","provider":"Viper Tactical ","version":"1.0","type":"link"}
