Feistis píopaí eitritheCuir dhá mhórchatagóir táirge san áireamh:
I measc na bhfeistis a fheidhmíonn mar rónta nasctha tá cúpláin dochta, cúpláin sholúbtha, teanna meicniúla, agus flanges eitrithe.
I measc na bhfeistis a fheidhmíonn mar naisc trasdula tá uillinneacha, tees, crosa, laghdaitheoirí, flanges dall, agus daoine eile.
Is éard atá sna feistis eitrithe a fheidhmíonn mar rónta nasctha go príomha ná trí chomhpháirt: gasket rubair ina saothraítear rónta, tithíocht cúplála, agus bolt glasála. Cuirtear an gasket rubair, atá suite taobh istigh, ar an taobh amuigh den phíobán le bheith ceangailte agus ailíniú leis an bpíopa réamh-ghreamaitheach. Déantar an tithíocht cúplála a dhaingniú ansin thart ar chuid sheachtrach an gasket rubair, agus ar deireadh thiar ceangailte le dhá bholg. Mar gheall ar dhearadh uathúil an gasket rubair agus an chúplála, tá airíonna rónta den scoth ag feistis eitrithe. De réir mar a mhéadaíonn an brú sreabhach laistigh den phíobán, cuirtear feabhas dá réir ar chumas séalaithe an naisc eitrithe.
Is féidir úsáid a bhaint as nasc píopaí, mar mhodh nasctha píblíne ard, in iarratais nochta agus folaithe araon, agus áirítear leis na hailt dochta agus solúbtha araon. Dá bhrí sin, tá réimse leathan feidhmchlár aige:
De réir Aicmiú an Chórais: Is féidir é a úsáid i gcórais uisce dóiteáin, córais uisce te agus fuar aerchóirithe, córais soláthair uisce, córais phíblíne peitriceimiceach, cumhacht teirmeach agus córais phíblíne mhíleata, córais phíblíne cóireála séarachais, etc.
De réir Aicmiú Ábhar Píobáin: Is féidir é a úsáid chun píopaí cruach, píopaí copair, píopaí cruach dhosmálta, píopaí cruach plaisteacha, píopaí iarainn insínte, píopaí plaisteacha tiubhaithe a cheangal, chomh maith le píobáin agus feistis comhla le joints píopa cruach agus le píopaí plaisteacha tiubha, chomh maith le píobáin agus feistis comhla le joints píopa cruach agus le píopaí cruach agus Ailt flange.
