Description 4uantum Airtight Magazine Sealant – High Viscosity Airtight Sealant is a precision-engineered silicone compound designed to restore and maintain airsoft magazine sealing performance. Offered by Defcon Airsoft, the UK’s leading airsoft online store, this formulation targets gas loss at the source, therefore improving consistency and reliability during use. This high viscosity airtight sealant is developed for GBB magazines, valve assemblies, O-rings and rubber gaskets where micro-gaps and surface wear cause pressure loss. Its dense silicone structure flows into uneven surfaces, thus forming a durable airtight barrier that supports full gas retention over longer periods. Key Performance Features High viscosity formulation: Creates strong adhesion on metal and rubber interfaces, which leads to improved seal stability under pressure. Silicone-rich compound: Conditions rubber O-rings and gaskets, thereby slowing drying, cracking and premature failure. Leak prevention and repair: Penetrates valve seats and sealing faces, as a result reducing gradual gas loss in GBB magazines. Pressurised application suitability: Performs effectively in high-pressure magazine environments, consequently extending service intervals. When applied to failing seals, 4uantum Airtight Magazine Sealant reinforces existing components rather than masking faults, which results in sustained pressure integrity. This makes it a practical maintenance solution for airsoft magazines where performance depends on consistent gas efficiency and dependable valve sealing.
