CH153 is a two piece single acting low pressure chevron seal which consists of one special formulated reinforced cotton fabric with nitrile rubber sealing element and one thermoplastic header ring. Due to the special formulated reinforced cotton fabric with nitrile rubber, the service life is much longer than the normal cotton fabric seals.
