In fluid power systems, power is transmitted and controlled
through a pressurized fluids. Connections
are made through the threaded ports on fluid conductor
fittings to tubes and pipes or to hose fittings and hoses.
These ports, which are an integral part of fluid power
components require a secondary seal to prevent metal-to-metal contact
that potentially can cause leakage.
ED Seals, also known as Captive Seals, ED Ring Seals, Fluid Connector seal, Elastomeric seal,
are specialized elastomeric seals conforming to the industrial standard DIN 3869 (as well as ISO 11926, ISO 9974, and ISO 1179)
Designed primarily for axial static sealing in threaded ports, stud ends, pipe connections, hydraulic plugs, and adapters within pneumatic and hydraulic systems, these shaped ED seals offer superior performance compared to standard o-rings, particularly under high pressure.
ED seals are essential components in high-pressure applications found in construction machinery, hydraulic presses, injection molding machines, fittings, valves, and general industrial equipment.
Advantages
• No relative movements during pressure cycles
• Cross-section remains virtually constant even
under high pressure
• Minimal mechanical deformation of the cross-section
• No twisting in the groove
• Wide operating temperature range
• Good compatibility with lubricants
• Meets ISO 1179 and ISO 9974 specifications
