What Are Reinforced Silicone Rubber Washers?
Reinforced silicone rubber washers are flat rings of material with Outer Diameter (OD) and Inner Diameter (ID) measurements. They are designed to:
- Reduce friction
- Stabilise surfaces
- Provide a level surface for nuts, bolts, or fixings.
- Serve as water-tight or air-tight seals.
Unlike standard silicone, reinforced silicone incorporates a glass fabric layer at the core, producing superior durability, tear resistance, and non-stretch characteristics. This makes them ideal for high-demand industrial, food, beverage, medical, aerospace, and automotive applications.
Washers can be cut as solid rings or with bolt holes along the flange to accommodate fixings.
Why Use Reinforced Silicone Rubber Washers?
Reinforced silicone rubber washers combine the flexibility and resilience of standard silicone with enhanced strength and durability. They are particularly effective in applications where non-stretch, tear-resistant seals are required. Key features include:
- High durability and tear resistance thanks to glass fabric reinforcement
- Odourless, tasteless, and non-toxic, making them suitable for food, beverage, and medical applications
- Wide operating temperature range: -62°C to +260°C
- Excellent resistance to UV, ozone, weathering, and moisture
- Maintains physical properties in extreme conditions
- Suitable for high-strength seals and spacers in demanding environments
Different Grades of Silicone Available
At Advanced Seals & Gaskets, we work with a vast network of suppliers to offer custom silicone washer solutions. Popular grades include:
- High-Temperature Silicone – for extreme heat applications
