Overview
This D-Shape Metal Retaining Washer is engineered for critical, high-pressure sealing applications in industrial piping and vessel systems. It is specifically designed to create a secure, leak-proof seal between flanged connections, capable of withstanding pressures up to 63 bar (approximately 914 PSI). The unique D-shaped profile, combined with a dual-material construction, ensures reliable performance under thermal cycling and mechanical stress, preventing gasket blow-out and maintaining system integrity in demanding environments.
Key Features
Dual-material construction for balanced performance and cost-efficiency
Integrated inner and outer retaining rings to prevent gasket collapse or extrusion D-shaped profile for secure positioning and alignment during installation Suitable for high-pressure applications up to approximately 914 PSI
Designed for use with standard metric flange connections
