Battery Case Seal

A battery case seal is a precision-engineered gasket designed to provide airtight, waterproof, and dustproof protection for battery enclosures in automotive, industrial, and energy storage applications. Made from durable elastomers, it ensures safe operation by preventing environmental contamination and electrolyte leakage.
Key Features & Benefits
✔ Chemical Resistance – Withstands battery acids, alkalis, and solvents (compatible with lead-acid, Li-ion, and NiMH batteries).
✔ Temperature Resilience – Stable performance from -40°C to 120°C (-40°F to 248°F).
✔ Compression Recovery – Maintains seal integrity under vibration/shock (ideal for EVs and heavy machinery).
✔ UV & Ozone Resistant – Long-term outdoor durability.
✔ Custom Profiles – Available as O-rings, flat gaskets, or extruded strips to fit battery case grooves.
Material Options
Material Best For Limitations
EPDM Weather/aging resistance Weak against oils
Nitrile (NBR) Oil/fuel exposure Limited high-temp use
Silicone Wide temp range, non-toxic Lower tear strength
Fluorocarbon Harsh chemicals (e.g., Li-ion) Higher cost
Applications
Electric Vehicle (EV) Battery Packs
Solar Energy Storage Systems
Industrial UPS/Backup Batteries
Marine/Military Battery Housings
Installation Notes
Surface Prep: Clean mating surfaces to remove debris.
Compression: Apply even pressure (avoid over-tightening).
Inspection: Check for cracks/swelling during maintenance.
