Product Description
Metal ring anti-rust treatment, rubber ring is generally used oil-resistant nitrile rubber or fluorine rubber. The combination pad has two sizes: metric and imperial, and the standard JB982-77 specifies the combination of metal pads plus rubber. The combined gasket is used for the sealing of threaded pipe joints and screw plugs. It is generally used together with the bayonet pipe joints to block the oil mouth. It is mainly used for the static sealing of the end surface at the threaded connection of hydraulic valve pipe joints. It is suitable for the end surface static seal of the British and American standard British thread Hefaguo and the German standard metric thread connection. The combined washer can be divided into A type and B type according to the structure form;
According to the different parts of the package, it can be divided into a whole package and a half pack.
Combination pads are widely used in pipeline systems with oil as the medium for welding, clamping, expansion of pipe joints, screw plugs, and mechanical pressure systems.
