Izigxivizo ze-Flange zinikeza umsebenzi wokuvalwa kwe-front-face static ngaphakathi koxhumano lwe-flange. Kunezimiso ezimbili zokuklama ezinkulu ezitholakalayo, kungaba ngengcindezi yangaphakathi noma yangaphandle. Imiklamo ehlukahlukene ohlwini olubanzi lwenhlanganisela inikeza izici ngazinye. Izigxivizo ze-Parker flange zinikeza ukusebenza okuthuthukisiwe kokuvala kusuka ku-free-free kuya kwezimo zokucindezela okuphezulu. Imiklamo ingathuthukiswa ukuze ingazweli eziqongweni zengcindezi, ibonise ukumelana ne-extrusion ephezulu noma ukumelana nabezindaba.
