Professional Applications & Engineering Value

This metal-bonded sealing washer is engineered to solve critical challenges in industrial sealing applications. The 304 stainless steel construction provides a strong, corrosion-resistant base that withstands harsh environments, while the integrally bonded EPDM rubber seal (Durometer 60A) ensures a flexible, impermeable barrier. This combination is vital for NEMA 4X rated enclosures and other demanding settings where protection against water, dust, oils, and mild chemicals is non-negotiable. By maintaining a reliable seal across a wide temperature range from -30°F to 200°F, it prevents equipment failure, reduces maintenance downtime, and extends the lifecycle of electrical cabinets, outdoor machinery, and processing equipment. Its precise dimensions for 1/4" screws ensure a perfect fit, simplifying installation and enhancing the overall integrity of the assembly.
