ʻEkolu ʻano kalaponahili kilaʻili o ka sila, ʻo ia hoʻi:
1, ka ʻili o ka tenon sealing: kūpono no ka mea hiki ke ahi, pahū, mea ʻawaʻawa a me nā manawa kiʻekiʻe.
2, ili hoʻopaʻa mokulele: kūpono no ke kaomi ʻaʻole kiʻekiʻe, ʻaʻohe mea ʻawaʻawa.
3, concave a convex sealing surface: kūpono no nā manawa kiʻekiʻe iki.

Kalaponahili kilaʻO ka gasket kahi ʻano apo e hiki ke hana i ka deformation plastic a loaʻa kekahi ikaika. ʻO ka hapa nui o nā gaskets i ʻoki ʻia mai nā ʻāpana non-metallic, a i ʻole i hana ʻia e nā ʻoihana ʻoihana e like me ke ʻano maʻamau, ʻo ka ʻikepili nā ʻāpana asbestos rubber, asbestos sheets, polyethylene sheets, etc.; Pono pū kekahi metala metala lahilahi (pepa hao, kila kuhiliʻole) asbestos a me nā mea metala ʻole ʻē aʻe i wahī ʻia me ka pahu metala; Aia kekahi ʻano puʻupuʻu puni i hana ʻia me ke kāʻei kila lahilahi a me ke kāʻei asbestos pū kekahi. He kūpono ke kīpē maʻamau no ka manawa o ka mahana ma lalo o 120 ℃; He mea kūpono ke kinoea asbestos no ka wela o ka wai ma lalo o 450 ℃, ʻoi aku ka mahana o ka aila ma lalo o 350 ℃, ʻoi aku ke kaomi ma mua o 5MPa mau manawa, e pili ana i ke ʻano corrosive maʻamau, hoʻohana maʻamau i ka pā asbestos kūpaʻa. I nā mea hana kiʻekiʻe a me ka pipeline, ke koho o ke keleawe, aluminika, ʻaʻole. 10 kila, kila kuhiliʻole i hana ʻia me ke ʻano lens a i ʻole ke ʻano ʻē aʻe o nā pahu metala. ʻO ka laula paʻi o ke kīʻaha kiʻekiʻe a me ka ili hoʻopaʻa he haiki loa (line touch), a kiʻekiʻe ka hoʻopau ʻana o ka hoʻopaʻa ʻana o ka ili a me ka gasket.
Kalaponahili kilai mea e pale aku ai i ke ano o ka rust, mawae, a pela aku, e like me ke ano o ka carbonhili kilaka uhi ʻana (zinka melemele, zinc keʻokeʻo, a me nā mea ʻē aʻe), a i ʻole ka ʻaila anti-rust a me ka pipi ʻana i ka hana pena anti-rust.
