OPIS
Zaptivni set P21 je zaptivka dvosmernog dejstva za zaptivanje klipa cilindra za uslove srednjeg opterećenja i kućište prema ISO 7425-1. Sastoji se od Polyurethane profilnog prstena i O-prstena kao elementa za prednaprezanje.
Karakteristike ove zaptivke su veoma visok statički i dinamički efekat zaptivanja, visoka otpornost na abraziju i nisko trenje bez pojave podrhtavanja kod klizanja.
