S-94610A309 0.812" ID x 2" OD Ultra-High-Temperature Ceramic Washers

Key Features & Benefits at a Glance

• Extreme temperature resistance - withstands continuous operation up to 3000°F without compromising structural integrity
• Superior chemical stability - maintains performance in corrosive industrial environments where metal washers would degrade
• Precise dimensional fit - 0.812" inner diameter ensures perfect alignment with 3/4" screws for secure fastening
• Optimal load distribution - 2" outer diameter provides excellent surface coverage to prevent component damage
• Consistent thickness control - 0.090-0.112" thickness range ensures reliable performance under compression loads
• Regulatory compliance assurance - meets RoHS 3 and REACH standards for safe use in regulated industries
• Non-conductive properties - ceramic construction eliminates electrical conductivity risks in high-temperature applications

Professional Applications & Engineering Value

These ceramic flat washers deliver exceptional value in extreme thermal environments where conventional metal washers fail. The off-white ceramic material provides outstanding thermal stability and resistance to oxidation at temperatures reaching 3000°F maximum temperature, making them ideal for furnace systems, high-temperature processing equipment, and thermal barrier applications. Unlike metallic alternatives that warp or corrode under intense heat, these high temperature washers maintain dimensional stability and prevent galling or seizing in critical joints. Their chemical inertness ensures reliable performance in aggressive industrial atmospheres, while the precise 0.812" ID and 2" OD dimensions provide optimal load distribution for 3/4" screw size applications in demanding thermal cycling conditions.
