Professional Applications & Engineering Value

This metal bonded washer solves critical sealing challenges in industrial environments where temperature fluctuations and high-pressure conditions compromise standard washers. The 304 stainless steel base provides structural integrity and corrosion resistance, while the fluorocarbon rubber seal maintains flexibility across the full temperature range from 0°F to 390°F. Engineering teams specify these washers for hydraulic systems, pneumatic equipment, and processing machinery where fluid sealing at 3400 psi is required. The permanent bonding between metal and rubber eliminates separation issues common in assembled seals, ensuring consistent performance in vibration-prone applications. The precise 0.364" ID guarantees proper fitment on 3/8" screw size fasteners, preventing misalignment that could compromise the seal interface.
