Button Battery Gaskets 304/316 Stainless Steel Circular Gaskets - Sealing & Insulation for Coin Batteries

Our circular button battery gaskets are precision-engineered components designed exclusively for button (coin) battery manufacturing and assembly. Crafted from high-grade 304 or 316 stainless steel, these gaskets serve as critical sealing and insulation elements, preventing electrolyte leakage, enhancing structural stability, and extending battery service life. With strict dimensional accuracy and smooth surface finish, they ensure seamless compatibility with standard button battery sizes, making them a trusted choice for electronics manufacturers, repair shops, and DIY enthusiasts worldwide.

• Dual Material Options: 304 stainless steel offers cost-effective corrosion resistance for standard applications; 316 stainless steel provides superior resistance to aggressive electrolytes and harsh environments, ideal for high-reliability devices.
• Precision Circular Design: Exact dimensional control ensures a tight, consistent fit with button battery casings, eliminating gaps that cause leakage or performance issues.
• Multi-Functional Performance: Acts as both a seal (preventing electrolyte leakage) and insulator (protecting internal components), boosting battery safety and reliability.
• Durable & Long-Lasting: Stainless steel construction resists oxidation, wear, and chemical corrosion, maintaining performance even in long-term use.
• Easy Integration: Compatible with automated assembly lines and manual installation, streamlining production processes and reducing labor costs.
