Professional Applications & Engineering Value

These metal bonded washers solve critical sealing challenges in industrial environments where temperature extremes and pressure fluctuations compromise standard washers. The 18-8 stainless steel base provides structural integrity and corrosion resistance, while the permanently bonded silicone rubber seal creates a reliable barrier against fluid and gas leakage. Engineered for 3/8" fastener systems, these washers deliver exceptional performance in HVAC, automotive, and processing equipment where thermal cycling from -100°F to 400°F would degrade conventional seals. The metal-to-rubber bonding technology ensures the seal remains intact during vibration and thermal expansion, making them ideal for pumps, compressors, and industrial machinery requiring dependable sealing under 100 psi pressure conditions.

Specification Summary & Compliance

Precision manufactured to inch system dimensions with 0.385" ID and 1.5" OD for consistent 3/8" screw compatibility. The 18-8 stainless steel construction meets industrial hardness standards at Rockwell B80, while the silicone rubber seal maintains Durometer 50A hardness for optimal compression. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards for global industrial applications. Temperature rating certified from -100°F to 400°F with maximum pressure handling of 100 psi for both fluids and gases.
