PRODUCTS
Sight glass gaskets are placed between the gauge glass and the main body of sight glasses to seal the sight glass and prevent media from leakage. Meanwhile, it also mitigates the action of impact force and prevent glass breakage arising from fast moving fluids.
Sight glass gaskets are generally used in tubular sight glasses and double window sight glasses.
According to the working environments of these instruments, sight glass gaskets are divided into non asbestos gaskets, graphite gaskets and PTFE gaskets.
Sight glass gasket
Category
Non asbestos gasket
It is a kind of general-purpose flat gasket made of reinforced high-grade non-asbestos fibers and bonded with heat-resistant nitrile rubber. It has excellent anti-sticking properties on both sides.
It is suitable for hot water, weak acids, weak bases, inert gases, etc.
Features
Graphite gasket
It is a traditional material used for sealing sight glasses. It is made of pure graphite sheet or metal reinforced graphite sheet after cutting or stamping.
It is suitable for hot water, weak acids, weak bases, inert gases, etc.
Features
PTFE gasket
It is constructed of 100% pure PTFE material. It has excellent resistant to temperature up to 260 °C and the pressure to 15 MPa under strong acid and base environments.
It is suitable for water, strong acids, strong bases, food grade media, oils, inert gases, etc.
