Professional Applications & Engineering Value

This metal bonded washer integrates an 18-8 stainless steel washer with a silicone rubber seal to address critical sealing challenges in industrial applications exposed to thermal cycling and pressure variations. The bonded design eliminates separate gasket handling, streamlining assembly while providing a uniform seal that resists compression set. Engineers benefit from its ability to maintain sealing efficiency in extreme temperatures from -100°F to 400°F, making it ideal for HVAC systems, automotive components, and processing equipment where thermal expansion and chemical exposure are concerns. The green silicone seal material ensures compatibility with oils and mild chemicals, reducing downtime due to seal degradation.
