High-Pressure ED Ring Seals for BSPP, Metric, and UNF Threads

Our high-performance ED Ring Seals are engineered for exceptional reliability in static sealing applications, particularly in hydraulic and pneumatic systems. Each ED Ring consists of a durable elastomeric O-ring paired with a rigid support ring to prevent extrusion under high pressure. These seals are perfectly suited for threaded fittings—such as BSPP, Metric, and UNF standards—providing a secure, leak-free connection even in demanding environments.

Available in a variety of standard sizes (e.g., G1/4, M14x1.5, 9/16-18), ED Rings are widely used in industries such as construction machinery, industrial automation, oil and gas, and agricultural equipment. With superior resistance to pressure, temperature, and hydraulic fluids, these seals are an essential component for any system requiring dependable static sealing.
