Professional Applications & Engineering Value

This metal bonded washer combines the structural strength of 18-8 stainless steel with the sealing reliability of black neoprene rubber to solve critical industrial challenges. The permanent bond between metal and rubber eliminates the need for separate gaskets while providing consistent sealing performance in applications exposed to moisture, dust, and mild chemicals. Engineered for No. 10 screws, this washer prevents fluid ingress and particulate contamination in electrical enclosures, machinery housings, and outdoor equipment. The temperature resistance from -40°F to 250°F makes it ideal for automotive, HVAC, and industrial machinery applications where thermal cycling occurs. The inch system dimensions ensure compatibility with standard North American equipment specifications.

Specification Summary & Compliance

This metal bonded washer features precise dimensions of 0.5" OD × 0.2" ID with thickness ranging from 0.084" to 0.114". Manufactured from 18-8 stainless steel with a permanently bonded neoprene rubber seal rated at Durometer 65A hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide. Designed specifically for use with No. 10 screws in inch measurement system applications.
