S-94709A121 0.12" ID x 0.25" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior sealing performance with permanently bonded neoprene rubber that prevents fluid and gas leakage in demanding environments
• Exceptional temperature resistance maintains seal integrity across a wide operating range from -40°F to 250°F
• Corrosion-resistant construction using 18-8 stainless steel ensures long-term durability in harsh industrial conditions
• Optimized vibration resistance through the metal-to-rubber bond design that prevents loosening under dynamic loads
• Precision dimensional fit with 0.12" ID and 0.25" OD ensures perfect compatibility with No. 4 screws
• Consistent sealing pressure from the Durometer 65A neoprene material provides reliable environmental protection
• Regulatory compliance assurance meeting both RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These metal bonded washers deliver critical sealing performance where standard washers fail. The 18-8 stainless steel base provides structural integrity while the permanently bonded neoprene rubber seal (Durometer 65A) creates an impermeable barrier against moisture, dust, and chemicals. Engineered for industrial applications requiring reliable vibration resistance, these washers solve common issues of seal degradation and fastener loosening in equipment exposed to thermal cycling from -40°F to 250°F. The black neoprene seal offers excellent UV and ozone resistance, making these inch system washers ideal for outdoor enclosures, electrical cabinets, automotive assemblies, and machinery where environmental protection is paramount.

Specification Summary & Compliance

Precision manufactured to exact inch system dimensions: 0.12" ID x 0.25" OD with thickness range of 0.105-0.140". Designed specifically for No. 4 screw size applications. The metal bonded construction combines 18-8 stainless steel with neoprene rubber seal (Durometer 65A) for optimal performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global industrial markets.
