Tombo manhole gasket

TOMBO™ No. 1374/13781420-ST/-S/-TH/1400-NA9094 

MANHOLE GASKET 

An endless gasket in which woven fabric is coated in a rubber compound and sewn together into various manhole shapes. This gasket has insufficient airtightness, so use it only for parts where some slight leakage is permitted.
It is best suited for applications in which the flange diameter is large, there is distortion, or a high clamping surface pressure will not occur.
