I-PEX copper fittings iyizinsiza zensimbi zensimbi ezisetshenziselwa ukuhlanganisa amapuleti e-PEX (amapuleti e-polyethylene axhunywe). Ngokuvamile zifaka ama-elbows, ama-tees, kanye nezixhumi, zifeza ukuhlanganiswa okuvalekile phakathi kwe-PEX pipe kanye ne-copper fitting ngezindlela ezifana nokucindezela, ukwandisa, noma ukuhlanganiswa okunezintambo. Zisetshenziswa kabanzi ekwakheni ukuhlinzekwa kwamanzi, izinhlelo zokushisa, kanye nokushisa ngaphansi komhlaba.

Isici esiyinhloko se-PEX copper fittings sitholakala ekuhlanganiseni izinzuzo ze-PEX pipes kanye ne-copper fittings: I-PEX pipes inikeza ukumelana nokugqwala, ukumelana nokuhudula, kanye nezinsuku zokusebenza ezinde (ngaphezulu kweminyaka engu-50), kanti i-copper fittings inikeza amandla aphezulu omshini, ukumelana nezinga lokushisa eliphezulu (ububanzi bezinga lokushisa obuvamile obusebenza -70℃ kuya ku-110℃), kanye nokumelana okuhle nokuhudula, kuqinisekisa ukuxhumana okuthembekile. Le nhlanganisela ikakhulukazi ifanele izinhlelo ezinezimfuneko eziphezulu zokuphepha nokuhlala, njengeziteshi zamanzi ashisayo nezibandayo ezikhaleni zangaphakathi kanye nezishisa phansi. Ngokwezigaba nezindinganiso, i-PEX copper pipe fittings kumele ihambisane nohlobo lwe-PEX pipe (isb. PEX-a, PEX-b, noma PEX-c). Izindlela ezahlukene zokuxhumanisa zithinta ukumelana nokushisa kanye nokumelana nokuphuka kwezinto zeph pipe; ngakho-ke, kubalulekile ukuqinisekisa ukuthi i-pipe fittings kanye ne-PEX pipes zisezingeni elifanayo futhi zenziwe ngezinto ezifanayo lapho kukhethwa amafitting. Imikhiqizo kumele ihambisane nezindinganiso ezihlobene, ezifana ne-GB/T 18992 mayelana nezilinganiso zengcindezi nezimvume zendawo, kanye ne-CJ/T205-2000 ne-CJJ/T98-2003 mayelana nokumelana nezinga lokushisa, izinga lokuxhumanisa (ngokuvamile 70%-89%), kanye nokumelana nokuhudula. Amafitting ngokwawo kumele adlule ku-95℃/1.5MPa ukuhlolwa kwe-hydrostatic futhi ahlangabezane nezidingo zamandla okudonsa.
