I roto i te umanga mīhini, me nui te tere o te tono o te rawhi, engari hei kaihoko, he maha atu ngā hua kei roto i te rawhi ina whiwhi pātai mai ngā kiritaki. I tēnei rā, ka whakaatu atu te ētita i ētahi atu āhuatanga pea o te rawhi ki a koe.

He mowhiti te mea e karapotia ana te rawhi, ā, ko te rauemi o te rawhi he rino kua whakakikoruatia, he kowiri tira (201/304/316). Tērā anō ngā kaihoko e kī ana i te mowhiti korokoro he rawhi. He kowiri tira te mea hanga o te mowhiti korokoro, ā, he rite te āhua ki te rawhi. Ko te nui o te rawhi o te ngongo te āhuatanga o te hononga me te piri. He mea whakamahi i te nuinga o te wā hei whakamau i ngā paipa taputapu miihini me ngā taputapu matū.

He maha ngā momo rawhi paipa, arā, he taumaha, he māmā, he āhua nohoanga ZR, he momo-O iri, he momo hononga-rua, he momo pūtu-toru, he momo-R, he momo-U, me ētahi atu. He pai ngā momo rawhi tuatahi e 6 mō ngā taputapu taumaha, ā, he matotoru hoki. Heoi, he rite ngā āhuatanga o ngā rawhi paipa momo-R me ngā rawhi paipa momo-U ki ngā rawhi, arā, ko ngā mea matua hei whakapiri ko ngā ngongo whakarewa, ngā paipa rapa, ka taea rānei te rawhi i ngā ngongo maha i te wā kotahi. Ko ngā momo matua ko: te rawhi paipa momo-R me te rīpene rapa, te rawhi paipa kirihou-tōngia momo-R, te rawhi paipa maha-paipa momo-R, te rawhi eke hoiho momo-U me te rīpene rapa, te rawhi paipa kirihou-tōngia momo-U, te rawhi paipa maha-paipa momo-U, te kōpaki rārangi tika. Ka taea te hanga i ēnei rawhi paipa ki te rino kua whakakikoruatia, ki te kowiri tira (201/304/316), ā, ka taea te whakarite i ngā whakatakotoranga hei tāpiri atu ki te paerewa ā-motu. Ko te rauemi o te rīpene he EPDM, he silica gel, me te rapa motuhake he mahi ārai mura. He pakari, he pakari hoki tēnei momo rawhi paipa whakarewa, he ātete pai ki te waikura, he ātete ki te wai, he ātete hinu, he ngāwari ki te wetewete me te whakamahi anō. He mea whakamahi whānuitia i roto i te hangarau hanga, i ngā taputapu mīhini, i ngā waka hiko hou, i ngā miihini ahumahi hiko, i ngā waka tereina hiko me ētahi atu mara.
