An Overview
(< >Combined Sealing Washer
>By The rubber ring and the metal ring are integrally bonded and vulcanized. It is a sealing ring used to seal threads and flange connections. The ring includes a metal ring and a rubber seal.
>The metal ring is anti-rust treated and the rubber The ring is generally made of oil-resistant nitrile rubber or fluorine rubber.
>Combined gaskets are available in metric and imperial sizes, and there are standards
B
>that stipulate the combination of metal pads and rubber for composite gaskets.
>Combined washers are used for sealing threaded pipe joints and screw plugs. They are generally used together with ferrule-type pipe joints to block oil ports. They are mainly used for end-face static sealing of the threaded joints of hydraulic valve pipe joints. They are suitable for End-face static seals at joints with British and American standard inch threads and French and German standard metric threads.
>Combined washers can be divided into

B
>types according to their structural forms. The difference of rubber coating can be divided into full coating and half coating.
>Second purpose description
>Suitable for welded pipe joints and ferrule pipes in pipeline systems where oil is the medium. Joints, flared pipe joints, hydraulic valve pipe joint plugs, screw plugs and pressure system seals of mechanical devices to prevent leakage of oil, fuel, water and medicines. Due to its simple structure, efficient sealing and low price, it is used in The machinery manufacturing industry is widely used.
