Key Features & Benefits at a Glance
- Superior sealing performance with bonded neoprene rubber that prevents fluid and gas leakage in demanding environments
- Excellent corrosion resistance provided by 18-8 stainless steel construction, ideal for harsh or outdoor applications
- Wide temperature tolerance from -40°F to 250°F, ensuring reliable performance in extreme thermal conditions
- Optimized for No. 10 screws with precise 0.25" ID, delivering perfect fit and consistent compression
- Durable bonded design where metal and rubber remain securely attached, preventing separation during installation or vibration
- Consistent seal hardness (Durometer 65A) offers ideal flexibility for effective sealing without over-compression
- Black neoprene seal provides additional UV and ozone resistance, extending service life in exposed applications
Professional Applications & Engineering Value
This metal bonded washer combines the structural integrity of 18-8 stainless steel with the elastic sealing properties of neoprene rubber, solving critical challenges in industrial assembly. The bonded construction eliminates gasket misalignment and separation under vibration, a common failure point in machinery and automotive systems. Its temperature resistance from -40°F to 250°F makes it suitable for outdoor equipment, HVAC systems, and automotive components exposed to seasonal extremes. The black neoprene seal with Durometer 65A hardness provides optimal compression recovery, maintaining seal integrity against oils, water, and weather elements while the stainless steel body resists corrosion in chemical environments. Engineers specify this washer for No. 10 screws when reliable sealing and corrosion protection are paramount in electrical enclosures, plumbing fixtures, and industrial machinery.
Specification Summary & Compliance
This metal bonded washer features precise dimensional specifications with 0.25" ID (for No. 10 screws), 0.562" OD, and thickness range of 0.096-0.135". Manufactured from 18-8 stainless steel with a permanently bonded neoprene rubber seal (Durometer 65A). The product meets industry standards for bonded sealing washers and is suitable for applications requiring temperature resistance from -40°F to 250°F. Materials comply with RoHS and REACH environmental directives.
