Product Description
Large Flat Rubber Washers are oversized sealing washers designed to cover large mounting areas and compensate for irregular or oversized holes. Their flat structure combined with elastic rubber material makes them ideal for preventing leakage, moisture ingress, and air gaps.
Thanks to their large outer diameter, these washers effectively seal uneven surfaces, bridge gaps, and provide reliable protection against water, dust, and oil penetration.
Large flat rubber washers seal oversized or misaligned holes where standard washers fail.
Functional Characteristics
- Large OD for wide sealing contact area
- Elastic compression fills surface irregularities
- Prevents water, dust, and oil leakage
- Acts as a spacer and sealing layer
- Suitable for static sealing applications
Material Selection
| Material | Sealing Properties | Recommended Environment |
|---|---|---|

| NBR | Oil sealing performance | Mechanical & automotive joints |
| Silicone | Soft compression, wide temp range | Electronics & thermal equipment |
| NR | Good elasticity | General sealing |
