He mea noa, he mea nui hoki te ngongo waipēhi rapa i roto i te tini o ngā mīhini ahumahi me ngā mīhini nekeneke. Koia te pūnaha waipēhi e whakawhiti ana i te wai waipēhi i waenga i ngā tāke, ngā papu, ngā takirere, ngā rango me ētahi atu wāhanga mana-waipēhi. Hei tāpiri, he māmā noa te whakawhiti me te tāuta i te ngongo, ā, ka mimiti i te wiri me te whakaiti i te haruru. He tino māmā te hanga i ngā huihuinga ngongo—ngā ngongo me ngā hononga e piri ana ki ngā pito. Ā, ki te tika te whakaritenga, ā, kāore e whakamahia kinotia, ka taea e te ngongo te mahi me te kore raruraru mō ngā rau mano o ngā huringa pēhanga.

Kei roto i ngā ngongo waipēhi he ngongo o roto, he paparanga whakakaha kotahi, neke atu rānei, me te uhi o waho. Me whiriwhiri ia wāhanga me te whakaaro ki te whakamahinga e hiahiatia ana. Ko ngā tawhā whakahaere me te mahi noa ko te rahi, te pāmahana, te momo wai, te kaha pupuri pēhanga me te taiao, hei tauira noa iho.

Kei roto i te ngongo o roto te wai, ā, ka ārai i te turuturu ki waho. Ko te momo wai waipēhi te mea e whakatau ana i te rauemi o te ngongo. I te nuinga o te wā, he nitrile, he rapa hangai rānei mō te hinu waipēhi kei roto i te hinu. Engari ko ētahi atu momo pēnei i te Viton, i te Teflon rānei ka whakamahia me ngā wai hangai pēnei i te phosphate ester.

Ka tiakina te paparanga whakakaha e te taupoki. Ko tētahi whakaaro i te wā e whakatau ana i te rauemi taupoki ko te ātete ki ngā pānga mai i waho pērā i ngā matū, te wai tote, te mamaoa, te hihi UV me te ozone. Ko ngā rauemi taupoki noa ko te nitrile, te neoprene me te PVC, me ētahi atu.

He mea hanga ā mātou hua katoa i raro i tētahi pūnaha whakahaere kounga tino pakari e whai ana i ētahi paerewa o te ao. Nō reira, kua whakarōpūhia ā mātou ngongo waipēhi e ai ki ngā paerewa e whai ake nei:

Raupapa EN 853 me 856:Ka kitea ngā ngongo waipēhi o tēnei raupapa me ngā hanganga whakapakari rerekē e whakaatuhia ana i roto i ngā paparanga whiri rerekē, i ngā paparanga porowhita rānei.

Raupapa SAE 100:Kua arotakengia ngā ngongo o te raupapa SAE 100 i runga i te hoahoa, te hanganga, me te whakatauranga pēhanga..
