Hoʻohana nui ʻia nā O-rings i nā ʻoihana like ʻole no ko lākou hiki ke hana i kahi sila ma waena o nā ʻaoʻao ʻelua.ʻO ke koho ʻana i nā mea O-rings e pili ana i ka noi a me ke kaiapuni e hoʻohana ʻia ai. Eia kekahi mau mea maʻamau i hoʻohana ʻia no nā apo-O:
Nitrile (NBR): He mea kaulana kēia no nā O-rings ma muli o kona kūpaʻa maikaʻi i ka ʻaila, wahie, a me ka wai.Hiki iā ia ke pale i nā mahana a hiki i 100 ° C.
ʻO Viton (FKM): ʻO Viton kahi fluorocarbon elastomer i loaʻa i ke kūpaʻa kemika maikaʻi loa, ʻoi aku ka nui o nā wela kiʻekiʻe a me nā kemika paʻakikī.Hiki iā ia ke pale i nā mahana a hiki i 200 ° C.
Silicone (VMQ): Ua ʻike ʻia ʻo Silicone O-rings no ko lākou maʻalahi a me ke kūʻē ʻana i nā wela wela, kiʻekiʻe a haʻahaʻa.Hiki iā lākou ke pale i nā mahana mai -60°C a i 200°C.
ʻO ka EPDM kahi lāʻau synthetic i kū maikaʻi loa i ka wā, ka ozone, a me nā kukui UV.Hoʻohana maʻamau ia i nā noi waho a hiki ke kū i nā mahana a hiki i 150 ° C.
Neoprene: Ua ʻike ʻia nā neoprene O-rings no ko lākou kūpaʻa maikaʻi ʻana i ka aila, ka wā, a me ka ozone.Hiki iā lākou ke pale i nā mahana a hiki i 100 ° C.
