Ko ngā hononga NPT, arā, ko ngā hononga National Pipe Taper, he momo hononga miro e whakamahia ana i roto i ngā pūnaha paipa me ngā pūnaha paipa. He miro whakarara ēnei hononga e hanga ana i te hiri ina whakakīia. He mea noa te whakamahi i ngā hononga NPT i roto i ngā tono e tika ana kia āraihia ngā turuturu, pērā i roto i ngā pūnaha wai, hau, hau rānei. E wātea ana ēnei i roto i ngā rauemi rerekē pērā i te parahi, te maitai kore waikura, me te kirihou, ā, he whānuitia ngā rahi hei whakauru i ngā diameter paipa me ngā kohao miro rerekē. He whānuitia te whakamahi i ngā hononga NPT i Amerika Te Raki me ētahi atu rohe, engari he mea tika kia mōhio kāore e hototahi ki ngā miro whakarara pērā i ngā mea e kitea ana i roto i ngā hononga British Standard Pipe (BSP).
Haunga ngā hononga whakapūmau paipa ā-Motu (NPT) e whakamahia whānuitia ana i Amerika Te Raki, he maha atu anō ngā hononga whakapūmau paipa paerewa ā-motu e whakamahia ana i ngā rohe rerekē o te ao. Ko ētahi o ēnei ko:
BSPP (British Standard Pipe Parallel): Ka whakamahia hoki i te UK me ētahi atu whenua e piri ana ki ngā paerewa o Ingarangi. He rerekē ki te BSPT, he miro parallel ngā hononga BSPP. I ētahi wā ka kiia ko ngā miro G.
BSPT (British Standard Pipe Taper): E whakamahia whānuitia ana i te United Kingdom me ētahi atu whenua e whai ana i ngā paerewa o Ingarangi. Ko te koki taper o ngā hononga BSPT he 55 nekehanga, ā, e kiia ana he miro R, Rp rānei.
JIS (Paerewa Ahumahi Hapanihi): E whakamahia ana i Hapani me ētahi atu whenua Āhia, he 30 nekehanga te koki whakarara o ngā hononga JIS, ā, he rite te hoahoa ki ngā hononga BSPT.

He torutoru noa iho ēnei tauira o ngā hononga paipa whakarara paerewa ā-motu, he rerekē ngā whakaritenga me ngā tikanga whakamahi o ia hononga. He mea nui kia whakamahia ngā hononga e tika ana mō tō tono motuhake kia pai ai te hototahi me te mahi.
