OPIS
Set zaptivki P20 je zaptivka dvosmernog dejstva za zaptivanje klipa cilindra. Primenjuje se za srednja opterećenja i ugradjuje u kućišta prema ISO 7425-1. Sastoji se od PTFE profilnog prstena i O-prstena kao elementa za prednaprezanje.
Karakteristike ove zaptivke su veoma visok statički i dinamički efekat zaptivanja, visoka otpornost na pritisak, ekstruziju, abraziju i nisko trenje bez pojave podrhtavanja kod klizanja.
PRIMENA
