Ahakoa i roto i te hanga kaipuke, i te hangarau ratonga hanga, i te umanga hinu kohuke, i roto rānei i te hanga mīhini, tipu me ngā teihana hiko - ko ngā hua elastomer i hangaia e tā mātou kamupene e arotahi ana ki te whakaiti i te kukū, te wehe i te haruru me ngā wiri, te mimiti i te whānui wera, te totohu rānei o te whare, me te whakatika i ngā hapa i te wā tāutanga. Ka whakawhanakehia e mātou ngā hua mō te whānuitanga o ngā tono rerekē.

Ko ngā hononga whānui rapa he hononga ngāwari i hangaia mai i ngā elastomers taiao, hangai rānei, me ngā papanga me ngā whakakaha konganuku i hangaia hei whakaora i te ahotea i roto i ngā pūnaha paipa nā ngā huringa pāmahana.
Ki te kore e taea te hoahoa i te ngāwari mō tēnei nekehanga ki roto i te pūnaha paipa, ko te hononga whānui te otinga pai. Ka whakatikatikahia e ngā hononga whānui rapa ngā nekehanga taha, takahuri me te koki, ka ārai i te kino me te wā kore mahi o te tipu.

Kei waenga i te ND32 ki te ND600. He tinana porowhita kotahi te EPDM/NBR, ka taea e mātou te hanga i te rahi e hiahiatia ana e te kiritaki.
He nairona whakapakari ā-roto me ngā mowhiti maitai.
I hangaia hei mimiti i ngā nekehanga whakawhānui, ngā wiri i roto i ngā paipa kawe wai.
Hanganga ngaru kotahi me te ngaronga kawenga iti.
Ka mimiti i te oro, ka wehe i ngā wiri mai i ngā taha katoa. Kāore e hiahiatia he hononga huihuinga.

Ka taea e te hanganga motuhake o ngā hononga rapa te whakaoti rapanga pēnei i
Wiri, Haruru, Ru, Waikura, Pakū.
Ngā ahotea, te ahotea o te kawenga, te nekehanga o ngā taputapu.
Te Wiri, te Pēhanga me te Nekehanga i roto i tētahi Pūnaha Paipa.

Tono
