❓ FAQ

Q1: What’s the difference between the inner and outer gasket?
➡️ The 60318 is the outer gasket, while part 60317 is the inner gasket. Both are used together to properly seal the observation glass assembly.

Q2: Can I reuse my old gasket?
➡️ It’s not recommended—once compressed or heat-cycled, gasket material can lose its seal integrity. Always replace with new OEM-quality parts.
