Description:Metal O-ring is unique gasket made of metal tube which is formed and buttwelded into a round shape or other shapes.
APPLICATION:The gasket is equipped with various advantages and it can be sealed with low tightening force, can be formed into various shapes according to the shapes of mating face and can be used for high temperature, high pressure and ultra-vacuum services. It is the most suitable gasket for sealing such machinery and equipments that space factor and compactness are accounted much of for their designs. Special surface coating is available according to necessity.DESCRIPTION:| Type | Basic type Metal O-Ring | Balanced type Metal O-Ring |
| Pressure | It is suitable for medium pressure service ranging from 10 -12 torr vacuum to 70kg/cm 2 [6.8 MPa], It is necessary to use with a retainer ring when used on raised or flat face flange. | The holes at the inside against internal pressure or at the outside external pressure.
