Ku bijyanye no gushyiraho imigozi mu turere aho ubushyuhe bw'itumba buhora bugabanuka munsi ya dogere selisiyusi - urwego rw'amajyaruguru ya Leta Zunze Ubumwe za Amerika, Kanada nyinshi, Scandinavie, Uburusiya, Mongoliya, n'ibikoresho biri mu butumburuke burenga metero 3.000 - ibikoresho bifite imigozi ya PUR (polyurethane) bigomba kugenwa nk'ibipimo ntarengwa, kandi ibikoresho byo gufunga bya silicone bigomba kugenwa aho ibikoresho bisanzwe bya NBR (nitrile). PUR igumana ubushobozi bwo guhangana n'ingaruka no kunanirwa kugeza kuri dogere selisiyusi -40, kandi ibikoresho bya silicone bigumana ubushobozi bwo gufunga no gufunga kugeza kuri dogere selisiyusi -50. Ibikoresho by'icyuma by'iyi konsulation bisaba kandi kwitabwaho mu gushyiraho ibikoresho bikonje: umuringa utwikiriwe na nikeli utanga uburinzi buhagije bwa slag n'imbaraga za mekanike ku bidukikije byinshi byo hanze, ariko mu duce dukonje cyane two ku nkombe - mu duce twa Noruveje, ku nkengero za Alaska, ku byambu bya Arctique y'Uburusiya - aho spray y'umunyu ihurira n'icyuma gikonje cyane, kitagira umushongi (AISI 316) hagomba kugaragazwa ibishishwa by'imashini kugira ngo hirindwe slag yihuta ibaho iyo umunyu utose kenshi bitewe n'ubushyuhe bukabije. Igiciro rusange cy'ikoti rya PUR, silikoni zifunga, n'ibishishwa by'icyuma kitagira umushongi kiri hagati ya 40-60% ugereranyije n'ibice bisanzwe bya M12 byo mu nzu, ariko iki giciro cyiza kirinda slag za PVC kuvunika, gutakaza slag ikandamijwe na gasket za NBR zikomeye, ndetse no kwangirika kw'ibishishwa by'umuringa bitera slag imburagihe mu bidukikije bikonje cyane.
