Umbhobho wotywino odibeneyo odibeneyo ophantsi wenziwa ngentsimbi ecwecwe kwaye udibanisa umoya woxinzelelo oluphezulu kunye nombhobho womphunga kumdibaniso othungelwe yiNPT oyindoda. Inomphetho ohlabayo wokudala itywina eliqinileyo kumbhobho xa isetyenziswa nge hose clamp okanye crimp sleeve okanye ferrule (engabandakanyi) kunye ne female National Pipe Taper (NPT) imisonto kwelinye ukudibanisa kuqhagamshelo lwentambo yeNPT yamadoda. Oku kufakwa kwenziwa ngentsimbi ecwecweyo yokuqina, ukuguquguquka, i-ductility, kunye nokumelana nokubola, kwaye inesihlalo sepolymer sokumelana neekhemikhali. Le Boss idityanisiwe ifaka ithumbu elipheleleyo lokutywina liyacetyiswa kwinkonzo yomphunga ukuya kuthi ga kwi-450 degrees F.
