4uantum

4uantum Airtight Magazine Sealant is a high viscosity airtight sealant formulated to restore and maintain gas retention in airsoft GBB magazines. Its silicone-rich compound bonds to valves, O-rings and rubber gaskets, thus sealing micro-gaps that lead to pressure loss.

Designed for pressurised magazine systems, this sealant penetrates worn sealing surfaces, consequently improving charge retention and consistency. Rubber components remain supple as a result, which supports longer service life and reliable magazine performance.
