Ko te pereki kauhanga karepe he mea tirohanga pūnaha hoki, e tika ana i waenganui i ngā puipui rua rānei, i ngā mīhini. E whakamana ana tēnei tika ki te whakaiti i ngā weheawehe me te whakatika i te mahi. Ka wehe mai hoki i te pereki kauhanga karepe keeke. Ka puta ai ngā weheawehe hei whakaora whanonga me te waewae noa.
He nui ngā whiwhinga o ngā pūtango kauwera i roto i ngā tāhuhu wai. E hanga ana ngā pūtango i runga i te mea hei tautoko i ngā wehewehe, i te paoroa me te mōhihi ki ngā rūma, e kitea nei i te kaupeka matua. Ko tēnā e hiaia ana kia whakamahi i aua i waenganui i te hunga tuhono katoa kihai i te tahutahu.
Ki te takawaenga i ngā tae me te whakapai i te mahi o te whenua, porohita Rama e anga whaihua nui ana. Kia whakatupu i te kawe pai i waenganui i ngā tāhuhu me ngā pūnaha, taea ai te whakarite i te paoroa me te pūnaha. Ko tēnei he mea nui rawa kia noho pai katoa me te whakahoki i ngā take.
Ka hanga ngā pūtango kauwera i runga i ētahi momo kaupeka katoa, ko ia ka noho ngā āhuatanga kē. Ko ngā rerekētu e mohio ana he neoprene, EPDM me te kaupeka silicone. Ko te neoprene kei tana uara ki te kai me ngā rūma, ko te EPDM kei tana uara ki waho atu nā runga i tana uara ki te rā, ā, ko te kaupeka silicone he taumata whakanui i te ara hotu nei nā runga i tana uara ki te uru.
He wā ka whakaaro nui ki ngā tohutohu e whai ake nei mō te kī tōpūtanga me te whakatūwhera i ngā pereki kauhere: Tuatahitia, ko te tīmatanga e hiahia ana koe ki te whiriwhiria i te mea tika hei pereki mō ōu pīpihua rānei, mō ōu mīhini rānei. Ka piipihia te pereki i waenganui i ngā rua mata ki te hanga i tētahi kuhu matua.

Ko mātou ki te Whare Kura o Boman Mechanical Technology e mohiotia ana he nui ngā take o ngā pereki kauhere mō ngā mahi ā-motu. He maha ngā pereki e taea ana kia whai mana i roto i te kauhere paiheihei hei tika mō ōu hiahia. E hanga ana ō mātou pereki hei whakamahere i tētahi kuhu matua, hei whakawehe i ngā weheanga, me te whakaae i te mahi pai.
