Metal Sealing Rings

DIN 7603 Type C Metal Sealing Ring

DIN 7603 Type C is a copper-jacketed sealing washer with an internal filler. Under tightening force, it conforms to minor surface irregularities and provides reliable static sealing.
 

It is suitable for threaded plugs and fittings in hydraulic, pneumatic, fuel, lubrication, and engine systems. Compared with solid metal washers, Type C can achieve effective sealing with lower tightening force while offering excellent pressure, temperature, and vibration resistance.
 

Key Features

• Metal-jacketed construction combining strength and flexibility
• Reliable sealing under high pressure and temperature
• Compensates for minor surface roughness and dimensional variation
• Compatible with oils, fuels, gases, and industrial fluids
• Available in customized sizes and material combinations

For optimum sealing reliability, replacement after disassembly is recommended.
